There's also a scanner on Microsoft's website that will scan for viruses and help remove them. \n\nI figure it's the least they could do for allowing so many problems. :)

Viruses come in all shapes and danger levels.  There is everything from trojans to everday viruses.  Most of these either alter data on your computer or they gather data from your computer for a certain person or company.  Either way they are dangerous.  There are some major ones taht alter boot data and cause your computer to no longer be able to start up properly.  Many of them some from websites without you knowing or from downloads (which you never download from someone that you do not know).  Get good antivirus software and keep it up to date and you should have no problems with it.\n\nOh, and most boot-up viruses do nto go away by reformatting your hard drive as they will "hide" in your RAM chips.  There are some sneaky ones out there, so make sure that you keep a good antivirus program on your computer, keep it active, and keep it up to date.

Another part of virus protection (and maybe the most important one) is the so-called resident protection (also known as on-access protection). Simply said, it is a program that continuously monitors the entire computer (the operating system and all running programs) and watches for suspicious activities (e.g. execution of a virus), thus avoiding/preventing a virus from damaging files on your computer.\n\n \n\nFrom the very definition of the resident protection, it is clear that most of the time it doesn't require any special care from your side. You don't have to execute it (it activates automatically when you start your computer) and if everything is OK, you won't even notice it is running. Its presence in the system is indicated by a small icon with the avast! symbol (lowercase 'a' in a ball) in the notification area (next to the clock). The second avast! icon, related to VRDB functions (see the help for more information), is also displayed here - as a lowercase 'i' in a ball. These two icons can be co-joined into one should the user feel the need to do so.\n\n \n\nSometimes, it may be practical to either pause the resident task, or maybe change its sensitivity. To do this, you can use the tiny resident control in the avast! simple user interface, by clicking the icon with the resident protection symbol - lowercase 'a'.\n\n \n\nMore detailed settings can be accessed by double-clicking the avast! taskbar icon.

free scans and removal tools are b.s. in my opinion.\nthey are limited in their capabilities.\nif you have internet service you shouldnt surf the web without an anti virus program running. \nits worth it to put the money out in advance because your system can get really screwed up without virus protection.

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. Some programs that w

A dangerous computer program with the characteristic feature of being able to generate copies of itself, and thereby spreading. Additionally most computer viruses have a destructive payload that is activated under certain conditions.\n\nA computer virus is a self-replicating program containing code that explicitly copies itself and can "infect" other programs by modifying them or their environment such that a call to an infected program implies a call to a (possibly evolved) copy of the virus

It isn't cleaned or removed because it isn't a virus. It's a system file, an index of the files in that folder, like a table of contents for the computer to read.

noting is safe from virus  you have to know how to use pc to keep safe \n\nuse \nKaspersky Anti-Virus 6.0\nscan pc in safe mode\n\nlets get that out of ur pc ur some antivirus will miss key keylogger and trojans . frist of all you need to download avg antispyware this is verry good in getting all kinda bad files . then you need to download Adaware\na-squared< is verry good in picking up traking software files that is on the pc and it will find them . then download antispyware blocker that will find any type of virus . trojans files with antispyware blocker when you run that at the top of the box ur see\nC:&#92; WINDOWS\nremove the word windows and just leave in\n\nC:&#92;\n\nthen hit scan it will search all of the pc every file for virus or trojans and this will not have any problem with ur antivirus you have i have this my self .\n\nthen download spyware doctor that will search the pc for even more spyware adaware . just having 1 or 2 antispyware dont cut any ice at all you neeed what i said to download . when you have them run ur pc in safemode and scan the pc with then 1 at a time . this way from safemode the trojan and keylogger cant hide them self coz there is not internet access on in safe mode all the software i said to download will get the trojans and keylogger\n\nif they say some are in the registry you watch what path there in and get in the registry and right hit on that folder and hit remove dont worry when the pc restart up win xp will creat a new clean folder for you

Of course it can. It's just a computer program, remember? It can do *anything* that is doable by a program - including stopping its spread and even removing itself from the infected machine. In fact, there are many viruses that spread only on certain dates or that stop spreading after certain dates.\n\nHowever, you can't rely on this. By far not all viruses are like this (in fact, only a disappearingly small subset of them are) and you can't know in advance whether the virus that has infected your machine is of this kind or not. Besides, even if the virus gives up and removes itself after a while, it can still do a lot of damage while it is still active.\n\nSo, you should run up-to-date anti-virus software and get rid of the virus, instead of waiting for it to "give up".

*claps* 3 people managed to say the exact same thing and STILL DIDN'T answer the question.\n\nYour asking how to remove a virus manualy from a computer, presumably you have already found it and the antivirus has said that it can not be removed.  This is probably because windows protects certian types of files from being accidently being deleted.  Your best bet is to reboot your computer into safe mode when it starts up, then run your virus scan again and it should be able to get rid of the virus.  To get into safe mode read this http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406?OpenDocument&src=sec_doc_nam\nIf that doesn't work, find the EXACT name of the virus and google it.  Usually Norton of Mcafee will have a information page about that particular virus and manual removal instructions which are usually quite longer than a reboot and try again.

If you think you can remove  virus by using system restore to the previous day before the infection, Forget it it doesn't work that way.\n You need to run your anti virus and see it the problem can be resolved,  If it doesn't you may have to download a better anti virus or go to a link that has specialty tools to help remove it.
