NO!!! u must not have two antivirus programs in your PC. Sometimes there will be software conflict. You must uninstall one of them. Don't delete them. you can get free antivirus from the internet I never buy.

All viruses are as bad. Perhaps the one damages hardware (not the crawling ants or flying moths, I mean the real computer virus) the BOOT SECTOR/PARTITION TABLE viruses\n\nThe most notorious network viruses are CodeRed, Nimda, SQLSlammer, and MSBlast.\n\nCodeRed spreads as a series of packets in system memory via network port 80 (http) by exploiting a vulnerability hole (MS01-033) in Microsoft IIS (Internet Information Service). \n\nNimda spreads via network port 80 (http) by exploiting a vulnerability hole (MS00-078) in Microsoft IIS (Internet Information Service). Nimda is considered a blended threat, since it also has the ability to spread itself across the network via shared drives and email attachments. \n\nSQLSlammer spreads as a series of packets in system memory via UDP network port 1434 (SQL) by exploiting a vulnerability hole in Microsoft SQL Server 2000 and Microsoft Desktop Engine 2000 (MSDE). \n\nMSBlast spreads via network port 135 (DCOM RPC) by exploiting a vulnerability in the Windows Distributed Component Object Model (DCOM) Remote Procedure Call (RPC) interface. It also uses several other network ports (UDP 69, TCP 4444) during its propagation.\n\n\nThere is a link with very good info on this subject\n\nhttp://www.robson.org/gary/writing/jcr-viruses.html\n\nIt talks about the notorious stealth viruses and polymorphic viruses\n\nE-mail is the worst source, am I right?

In computer security technology, a virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents. A computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells. Extending the analogy, the insertion of a virus into the program is termed as an infection, and the infected file (or executable code that is not part of a file) is called a host. Viruses are one of the several types of malicious software or malware. In a common parlance, the term virus is often extended to refer to worms, trojan horses and other sorts of malware, however, this can confuse computer users, since viruses in the narrow sense of the word are less common than they used to be, compared to other forms of malware. This confusion can have serious consequences, because it may lead to a focus on preventing one genre of malware over another, potentially leaving computers vulnerable to future damage. However, a basic rule is that computer viruses cannot directly damage hardware, but only software.\n\nWhile viruses can be intentionally destructive (for example, by destroying data), many other viruses are fairly benign or merely annoying. Some viruses have a delayed payload, which is sometimes called a bomb. For example, a virus might display a message on a specific day or wait until it has infected a certain number of hosts. A time bomb occurs during a particular date or time, and a logic bomb occurs when the user of a computer takes an action that triggers the bomb. However, the predominant negative effect of viruses is their uncontrolled self-reproduction, which wastes or overwhelms computer resources.\n\nToday (as of 2006), viruses are somewhat less common than network-borne worms, due to the popularity of the Internet. Anti-virus software, originally designed to protect computers from viruses, has in turn expanded to cover worms and other threats such as spyware.\n\nDefinition:\n===========\nA virus is a type of program that can replicate itself by making (possibly modified) copies of itself. The main criterion for classifying a piece of executable code as a virus is that it spreads itself by means of 'hosts'. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable medium. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with worms. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms.\n\nViruses can infect different types of hosts. The most common targets are executable files that contain application software or parts of the operating system. Viruses have also infected the executable boot sectors of floppy disks, script files of application programs, and documents that can contain macro scripts. Additionally, viruses can infect files in other ways than simply inserting a copy of their code into the code of the host program. For example, a virus can overwrite its host with the virus code, or it can use a trick to ensure that the virus program is executed when the user wants to execute the (unmodified) host program. Viruses have existed for many different operating systems, including MS-DOS, AmigaOS, Mac OS and even Linux; however, the vast majority of viruses affect Microsoft Windows.\n\nA legitimate application program that can copy itself as a side-effect of its normal function (e.g. backup software) is not considered a virus.

Hey pal,\n\nNowadays making a virus is not so difficult, every programmers who worked more than 1 year can do this.\n\nSo there are alot of virus to find out.\n\nCiao,

each virus is different, so you'd need to know which one it was...or know in-depth how your os works (and that is a book, not a post at yahoo answers)

In addition to Hybrid's answer:\n\nDepending on the severity/quantity of viruses, you may want to look into:\n\n1) If you have an anti-virus program, run a full scan on your system. Look for McAffee or Norton antivirus tools in "programs" for starters.\n\n2) If you have no antivirus program installed, try AVG free addition. It is easy to install and you'll receive regular updates to counter new virus attacks. You can also use tools to run full scans on your system. You can download it at: http://free.grisoft.com/doc/2/lng/us/tpl...\n\nOr, try the following link:\nhttp://housecall.trendmicro.com/...\n\n3) If a PC is plagued with viruses, your best bet is to clean the system BEFORE it boots. This can be done by using some free tools available. Check out:\n\nhttp://www.nu2.nu/pebuilder/intro/...\n\nYou use PE Builder to make a bootable CDROM that loads a windows-like interface in memory. Because none of your hard drive files are locked they can be cleaned of any viruses. BartPE provides free McAffee plugins that you can run to accomplish this. WARNING: you have to fairly computer savy to work with BartPE. You may want to recruit a friend to help. It's more work, but I've found this to be the most effective way to clean your system.\n\nHTH,\nD

In answering your question I will assume that you have a Windows XP computer.  It would also be very helpful if you could provide further technical information about your computer system and can describe the computer’s behaviour in more details, otherwise most people can only provide you with general information. For an example of what information you can provide, visit my web site resources below.\n\nDoes Windows need all those 40+ processes?  Some processes may be running more than once as they may be needed by more than one application dependng on what it is that you are running.  Other processess are mandatory for Windows to function reliably.  But you may also have malicious processes running and these are the ones that you want to delete permanently.  The only way that I know to find out about all those Windows processes is to search for more information about each one using a process library database. When you discover a malicious process, delete it and restart your computer to see if it comes up again.  If it does appear again, then you need to do a deeper and thorough scan of your computer to remove the root application.\n\nCheck out the resources below for additional tools and information to help you out.

Infected.  Only Microsoft suffers the "114,000 Microsoft Virus Definitions".  There are 811 Other OSes, that are virus free, and most are free and cost you nothing.\n\nYep, you would probably spend some time getting used to the new one you choose, but, it will be lots less time than you are spending right now, on Microsoft updates, upgrades, anti-malware, anti-Spybot, anti-virus, frustration!\n\nPlus, the other 811 OSes are all based upon Unix, which runs upto 50X faster than Microsoft XP.  \n\nMicrosoft runs Linux on 45,000 servers and computers at Redmond Campus, Hotmail.com, Microsoft.com, MSN.com, and all corporate routers, and firewalls. \n\nLinux saves Microsoft from the Internet!   \n\nI recommend that you try out http://pclinuxos.com (with 1900 FREE games, programs, applications!) .\n\nDownload, burn to CDrom, reboot so it runs in RAM disc, and you can install by clicking the Icon on the desktop.  Provides 20 desktops (right click on screen, "configure Desktop"). \n\nThousands of helpful friends are on the forums, 24/7/365!
