How do you remove the issas.exe computer virus?
(Same as How Do You Remove a Computer Virus) There are many different kinds of "computer virus'." Many people confuse the terms: malware, spyware, and adware, assuming they all are the same as a "Computer Virus." This is not so, though many of such kinds of malicious applications can be quite easily removed. Step 1: Download an Anti-Virus application. Good examples of this are: Spybot Search and Destroy Microsoft Windows Defender Norton 360 (not free) AVG Anti-Virus Avast! Trend Micro Etc. The list goes on, and on... You can see the corresponding links to each recommended anti-virus application in the "Related Links" below. (Note: There has been debate over the possible problems that may arise with having multiple anti-virus applications installed, yet this has not been widely confirmed and is mainly an individual problem with few computers.) Step 2: Download and Install updates for the installed anti-virus application and then run a "Full Scan" of your computer to attempt and detect any malicious activity. Step 3: Follow the instructions given by the individual anti-virus application to remove the malicious application(s). Step 4: Install security updates on your computer. Separate from updates for individual anti-virus applications, it is highly recommended you download and install updates for your operating system. A corrosponding link is given in the links below for Microsoft Windows updates. Step 5: Stay safe by downloading and installing proper security tools. These tools could include: CCleaner (Cookies and Registry Cleaner) McAfee Site Advisor (Idenitifies Malicious Websites) WOT (Identifies Malicious Websites) The corresponding links are given below under "Related Links" as well. Other s Well you can't just ask how to remove a computer virus. There are thousands of variations of viruses. Each one having different code and as such some are harder or easier to remove. To remove a virus software quarantines the file that is infected, delete the file, clean the infected file of the virus or deny the virus access. If you suspect or if you confirm that your computer is infected with a virus, obtain current antivirus software. For more information about antivirus software vendors, click the following article number to view the article in the Microsoft Knowledge Base. Antivirus software helps protect your computer against most viruses, worms, trojans, and other malicious programs. Many computers come with antivirus software installed. You can also purchase antivirus software, and you can install it yourself. In this scenario, you must also keep the antivirus software up to date. A firewall is software or hardware that creates a protective barrier between the computer and potentially damaging content on the Internet. A firewall helps guard the computer against malicious users and against many computer viruses and computer worms. Use a firewall only for network connections that you use to connect directly to the Internet. For example, use a firewall on a single computer that is connected to the Internet directly with a cable modem, with a DSL modem, or with a dial-up modem. You can use the same network connection to connect to the Internet and to a home network or to an office network. In this scenario, use a router or a firewall that prevents a computer that is connected to the Internet from connecting to the shared resources on the home computer or on the office computer. Do not use a firewall on network connections that you use to connect to your home network or to your office network unless the firewall can be configured to open ports only for your home network or for your office network. Updates help shield your computer from vulnerabilities, from viruses, from worms, and from other threats as they are discovered. Steps that you can take to update your computer include the following: Install updates for Windows and for Windows components such as Internet Explorer, Outlook Express, and Windows Media Player Install updates for Microsoft Office programs. Install updates for other third-party programs on your computer. For more information, contact the manufacturer of the third-party program. Additionally, install security updates for other Microsoft products that are on your computer, such as Internet Information Services (IIS), Microsoft SQL Server, Microsoft Exchange Server, and other products. If you are running a version of Microsoft Outlook that is earlier than version 2002, make sure that the Outlook e-mail security update is installed on the computer. For more information about the Outlook e-mail security update If you are running Outlook Express, use caution when you open e-mail attachments. Disable active scripting in Outlook and in Outlook Express. Steps to remove a virus: Visit the Protect Your PC site and install the latest updates. If you currently use antivirus software, visit the manufacturer's Web site, update it, and then perform a thorough scan of your system. If you don't currently use antivirus software, subscribe to a service and scan your system immediately. Download, install, and run the Malicious Software Removal Tool (for Microsoft Windows XP or Windows 2000 users). Note that this tool does not prevent viruses from infecting your system; it only helps to remove existing viruses
How do you connect a laptop to a PC?
There are mainly three ways of connecting a Laptop to a PC 1)Through LAN 2)Through Bluetooth 3)Through Wireless Router The first one doesn't need any s/w(software), but a LAN card or NIC(network interface card) Ethernet Card , and a Twisted pair cable with RJ(register jack)45 crimped through cross over crimping on either sides of the wire. The second one needs to have a Blue tooth dongle either inbuilt or an external one connected to both the Laptop and a PC.You need to install Blue tooth drivers. The third one requires a Wireless Router that connects to your Internet Modem and broadcasts your signal wireless allowing computers to join your network. Once connected by network, have both computers join the homegroup and share files and folders. From each computer, depending on the shared folders, you can access the data on both the laptop and PC and therefore connecting them for easy transfer of data and anything else you might want to do. There are several ways to connect a laptop to a PC. If you have an Ethernet card installed on your laptop and on your PC you can directly connect them with a cross-over LAN cable (in case You don't have network hub). or a straight LAN cable (if you are using a network hub or network switch between the computers). An ad-hoc wireless network if your PC and Laptop both have wireless cards. You can also get a special USB cable that connects 2 computers and allows data to be transferred between them. They are quite cheap and you can definitely find one on Ebay. Option 1 generally no longer requires a special crossover cable. Most modern NICs (especially on laptops) will auto-sense which pairs they need to use for Tx/Rx.
How do you open .dll files to see what is written inside?
A DLL is a library file that contains functions for other programs to use. In order for these functions to be run their code must have been compiled. Compiling is the process of taking source code in a language like C++ or Visual Basic which can be read by humans, and converting it into machine code that can be read by a computer processor. As such it is very hard to 'read' DLL files as the actual functional code is machine code. In order to read the source code you would have to attempt to reverse-engineer the machine code. Reverse compilation is touchy legal area which is usually very hard as the machine code may have been written in any high-level language, you would have to find out which one it was written in to have good shot of decompiling it. It would also likely be encoded. You can use a program such as "DLL Export Viewer" (see Related link below) to 'view' DLL files.
How do you network two PCs together directly using a cat 5 cable?
Easy Setup: Connect 2 Computers Directly Using Crossover Cable http://www.home-network-help.com/crossover.HTML you will need a crossover cable to do this. pairs are switched allowing communication to occur without a hub or router TAKE THE CAT5E CABLE AND TWO JACKS.YOU WILL FIND 4 PAIRS OF WIRES. LIKE OW-O,BLUEW-BLUE,GREENW-GREEN,BROWNW-BROWN. IN THIS THERE ONLY FOUR WIRES ARE NEEDED. supoose you have crimped one side like this ow-o-gw-g-blw-bl-brw-br.then other end will be gw-bl-ow-bl-o-brw-br. ow-orange white o-orange blw-blue white bl-blue grw-green white gr-green brw-brown white br-brown COLUR CODE : 1----3 2----6 3----1 4----4 5----5 6----2 7----7 8----8 And Both computers need to have a NIC(Network Interface Card) installed. The computers need to have different IP addresses in the same IP subnet. This gets set in Network Properties - TCP/IP Properties. Easiest would be to set one at 10.0.0.1 and the other at 10.0.0.2, both with a netmask of 255.255.255.0 SOMTIMES A NIC will have the crossover setting in the device driver

Does every computer have a modem?
No. The IRS, for instance, processes your tax return on computers that - quite wisely - do not connect to the internet. When your return is submitted, it ends up on storage media which is hauled on carts across the hall to computers that calculate your refund or amount due. You can imagine how much a clever virus writer could make otherwise. A modem is a modulator/demodulator, which converts between electronic signals and the sounds transmitted by a POTS (Plain Old Telephone Signal) line. Those likes have a top speed of only about 53kbps - too slow for much of anything these days except FAX, which runs at 9600 bps. Broadband "modems" are not really modems.

Who invented the ball?
If you mean for sport it is doubtful there is enough recorded evidence to exactly pinpoint any one person or culture. Regardless from watching several TLC documentaries. The ancient Aztecs played a form of basketball with a hoop placed on the side of a wall. They used a crude leather ball. Ancient Egypt was known to play an early form of soccer with a somewhat circular shaped object. The first official balls were manufactured by Charles Goodyear in 1836. Other than that read this. "Through out history, humans have enjoyed kicking a ball or something like a ball. South American Indians were known to use a light elasticized ball. However; rubber was not to be practically manufactured until a few thousand years later. According to historical references and legend, early balls ranged from human heads, stitched up cloth, animal and human skulls to pig or cow bladders. During the Ts'in and Han Dynasties (255 BC-220 AD), the Chinese played 'tsu chu', in which animal-skin balls were dribbled through gaps in a net stretched between two poles. Certain ancient Egyptian rites are said by historians to have similarities with football, and both the ancient Greeks and Romans also played a game that entailed carrying and kicking a ball. According to pre-medieval legend, an entire village would kick a skull along a path to a nearby village square. The opposing village would in turn attempt to kick the skull to the first village's square. Wow, that probably caused more riots than in modern soccer games. A Medieval custom was to take pig bladders used from live stock killed in preparation for winter sustenance and inflate them. They would play a game using their feet and hands to keep the "ball" in the air. Sounds like hacky sack to me. The animal bladder balls were eventually covered with leather for better shape retention."
What are the advantages of wireless modem?
1. A wireless modem is a machine that is able to receive and transmit a network signal, like the Internet, without the use of cable connections and transmitting it to other units. 2. A Wi-Fi network gives you the freedom to be online anywhere in your house that is in range of your modem's Wi-Fi signal. 3. Which will provide the fastest, most reliable, and least expensive service. 4. wireless modems allows for access to the Internet almost anywhere that connection speeds may be slower than they would be through a wired line or Wi-Fi. 5. Speed of wireless broadband connections are always improving, however, and some providers may be able to rival the speeds of standard cable Internet. networkrepairs.ca

What is NAND gate in semiconductor devices?
A NAND gate is digital logic device which will have 2 or more inputs which can be logic 1 or logic 0 (on or off, high or low) with all the inputs at logic 0 the output will be at logic 1, the only time the output will switch to a logic 0 is when ALL the inputs are at logic 1. here is a simple "truth table" To show the basic operation Input1 Input2 Output Off--------Off------- On Off--------On------- On On--------Off------- On On------- On------- Off NAND stand for not AND therefore a false will be present on the output only when both input are true ANSWER: NAND stands for NOT AND it simply negate the function. The only time that the output can be false if all inputs are true. In logic functions there is no ON-OFF it is either true or false "1" or "0"

What is a POP mail server?
Answer A Post Office Protocol (POP) mail server is a server that complies with the RFC standard 1939. Here is a basic run down. The Post Office Protocol - Version 3 (POP3) is intended to permit a workstation to dynamically access a maildrop on a server host in a useful fashion. Usually, this means that the POP3 protocol is used to allow a workstation to retrieve mail that the server is holding for it. POP3 is not intended to provide extensive manipulation operations of mail on the server; normally, mail is downloaded and then deleted. A more advanced (and complex) protocol, IMAP4, is discussed in [RFC1730]. Answer A POP mail server (or simply "POP server") is the most common form of incoming email server. Basically, the POP server is what receives the email and is almost always used with an SMTP server, which is the outgoing server. The best way to find out the address of your POP server is to ask the company who is providing your email service. You will need to know this information if you are planning to set up an email client such as Thunderbird, Outlook, or Eudora to access your email. Answer POP (Post Office Protocol) mail client programs (e.g., Eudora, Netscape Communicator, Microsoft Exchange, Microsoft Outlook) allow you to retrieve your e-mail from the central server to your local computer. When someone sends you an e-mail message, the message is received, processed and stored in your mail file on the central mail server (for most this is slate). You can access your e-mail: 1) locally by logging onto the mail server and using a mail client program (e.g., "pine" or "elm"); or 2) remotely by using a POP/IMAP client program. With a POP client your e-mail is copied/retrieved from the mail server to a local computer. With an IMAP client your e-mail is accessible remotely, but is stored and managed on the server. (A subset of POP e-mail client programs also function as IMAP clients. The advantages and disadvantages of POP vs IMAP are discussed in the "Electronic Mail Quick Reference" guide. IMAP configuration is discussed in the "IMAP Quick Reference" guide.)
How do you hook up a DSL connection to your computer?
the actual physical connection is simple, almost every DSL provider will sell/lease you a modem, and probably install it, either free or for a price. The DSL modem connects either to your phone line, a fiber optic line (if your in a large city) or most commonly a coaxal line, just like your tv. That modem, also connected to the power outlet, is then connected to your computer via a jumper Ethernet line, commonly Cat5e. You could also connect a router to the modem instead, and then connect your computer to the router via another Cat5e line, or Wifi. This is only required when you are connecting many computers to the same internet connection, or when you really need Wifi for a laptop or remote computer.

What is advice on building your own computer?
Brand-name computers are good quality but building your own can save you money and get you exactly what you want. Brand-name is good quality, but they often bundle there PC's with lots of accessories and junk software that you probably will never use, and they jack up the price for it. I have recently built my first PC, it was surprisingly easy and fun. The first thing you should have in mind is what you want it to do, I built mine for games, so having upgradeable hardware is key...I wanted to be able to upgrade my graphics later on.. So you need to keep things in mind like this, do you want on-board video or not? I started with the motherboard and built around that. You need to fully understand that certain parts only work with certain parts e.g. you CANNOT stick a AGP video card into a PCI-E slot and expect it to work if you get my drift. Same goes for CPU/Mobo/RAM ect. So if you're building going from the ground up you need to remember this stuff, you CANNOT stick a 775 socket CPU in a 774 socket Motherboard. You will end up damaging both the CPU and the MOBO. So keep that in mind, when you buy a Motherboard you should get a list of all the compatible hardware/software...Also there are lots of different Case types like : ASUS, Abit, MSI, DFI, ATX which all have different screw holes for the Motherboard and power supply...So advice would be to start with the motherboard and build up from that using the recommended hardware for the motherboard. Find a case that fits, make sure you have a Operating system disk handy, and make sure that OS is supported by all of your hardware. You may also want to install the CPU yourself to save a lil money or you could opt for a Mobo w/pre-installed CPU and make things MUCH easier. I installed my CPU by myself was worried about it at first hearing a lot or horror stories of things going wrong, but personally I found it easy and had no problems installing the CPU whatsoever. Make sure you do the research first before attempting to install a CPU because you could easily destroy a CPU if you don't know what your doing. Don't be afraid to use a walk-through! It's a great feeling once you get her up and running and installing your new operating system :) _______________________ I'm 17, and have been building my own PCs for just over 5 years now. It's not as hard as they say... You have to decide what you want the PC for, gaming, work, server management etc. After that, you need to decide what the best hardware is for your specific purpose (speak to a local PC dealer or two). E.g: For gaming, you want a dual core CPU at minimum (quad core or higher preferred). So make sure the motherboard can handle a good CPU as well as lots of ram (+- 8 gb) and pci-e slot. If you can get a SLI compatible board then go for it (can connect to graphics cards of the same type to double memory). Also aim for a gigabit on-board network card and 5.1 channel sound card. A good hard drive is essential (250gb should do at first). Make sure your mother board can handle SATA (Serial-ATA) drives as they transfer data at a much quicker rate than the old IDE... I would suggest going for a Gigabyte mother board if it is your first build. They are easy to manage and very reliable.

What is the use of logic gates in fm transmitters?
They can be used for error checking. If the transmitter is off frequency, the logic gates can be used to inhibit the transmitter, to stop interference. Early forms of PLL (Phase Locked Loop) control may also use logic gates to act as dividers. This is normally taken care of by a single dedicated chip, these days.
