Answer . They do different things. The most recent "viruses" are really technically called "worms". These programs are usually loaded as attachments in emails, and then silently send out emails to everyone in your contact list. Other viruses attach part of their code to your device drivers, or… commonly used programs, so that whenever you run that program it runs as well. Some will delete or rename important files, some will broadcast your information out to other computers, and some will attempt to perform operations that could damage your hard drive, etc.. (MORE)

Firstly, it should be 'What are computer viruses?', or 'What is a computer virus?'. But to answer the question, a virus is a a harmful or malicious script or code which may harm your computer. These should not be confused with Trojans or Worms. Trojans Trojans horses are just like in the story of …troy: They are something bad wrapped up in something good. You may be downloading a video from the internet and get the video, but with it will come a device that will attempt to hack your computer or get you to buy some piece of software for a very high price. A Trojan horse is a file that appears harmless until executed. A good example is WinAntiVirus, a Trojan that comes bundled with a download that you, yourself wanted to download. It convinces you that there are hundreds of viruses on your computer, that this "new and efficient" program can detect. It will try and make you buy the full WinAntiVirus for hundreds of dollars or pounds, and when you buy it the whole thing clears off of your system, leaving you confused with empty pockets. Something even more shocking is that the person who owns WinAntiVirus makes nearly 6 million dollars (3 and a half million pounds) every year. Bear in mind that YOU MUST DOWNLOAD THE TROJAN FOR IT TO GET ONTO YOUR SYSTEM. Most good antivirus systems will get rid of these trojans. Viruses A computer virus is a script that can copy itself and infect a computer without permission or knowledge of the user. However, the term "virus" is commonly used, albeit erroneously, to refer to many different types of malware programs. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus. 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 the Internet, or by carrying it on a removable medium such as a floppy disk, CD, or USB drive. 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. In easier language, viruses can copy themselves, and those copies can copy themselves, but all copies can do the same thing-usually destroy files (which could be critical files) or hack the system (attempting to obtain personal details). Worms Finally, a worm is the most independent. A worm can spread itself to other computers without the user actually doing anything. A good example is an email worm. An email worm comes in an email, and as soon as the user opens it the worm duplicates the email, sending it to all contacts on the users list. When those users open it the same thing happens, so the link can go on forever. Sometimes they are harmless, but it is more common that they delete files-causing a nuisance to the user. In some cases the worm may permanently shut down your computer. Worms usually come in the form of Spam. (MORE)
Bad People create viruses to assess your computer or use it, and for how the get them, the virus self-installs or waits for you to run an innocent-looking program. top 10: 10: ILOVEYOU 9:cih
Viruses are programs that attach themselves to a computer or a file and then circulate themselves to other files and to other computers on a network. They usually affect the data on a computer, either by altering or deleting it. Worms, unlike viruses don not need the host to attach themselves to.

viruses go into your computer when you go on websites you've never heard of or they have inappropriate things on them.beware of these websites and if you accidentally end up on those websites quickly get off.
Thousands of viruses are made everyday. **** Clarification **** Thousands of variants of viruses are made daily, mainly by "Script Kiddies" who get some viral code, modify it a little bit, and re-distribute it. --Greg
A computer virus can be introduced in a variety of different ways. These include email/USB Thumb Drive (in fact any removable media)/ and simply visiting websites which download malicious cookies onto your computer (most websites automatically download data when you visit them).

There are no active viruses attacking Mac OS X. If you are running Windows on the Mac then it can become infected with the many viruses that attack Windows.
Nobody keeps tracks of "new" computer viruses, as almost all are offshoots of existing ones. However, according to a Symantec (anti-virus manufacturer) report found on the CERT (USA Government office; Department of Homeland Security) website (refer to the link, below), "nearly 7,000 new worms and v…iruses . . . in the first half of 2006; this is the highest number ever recorded for a 6-month period." Given that figure, one may derive that over 1,166 worms and viruses are created per month.. As an aside, according to the Computerworld link, below, the total number of viruses created as of the end of 2008 reached the one million mark, with over 25% of them having been created in the latter half of 2008, alone. Given that the numbers have been tracked since 1988, that would average to over 4,166 viruses per month. (MORE)

you get viruses in your computer by multiple ways, if your computer is connected to internet then you may get viruses from email, IM and also from some websites! Also if you are into warez and download lots of pirated stuff then there is a high risk of getting infected from viruses! also virus… can come from CD's and USB's memory sticks! (which is mostly in the form of autorun)! Its important that you keep your softwares updated and use a good antivirus software! also it's important that if you have an antivirus installed and if it detects a virus then it is highly recommended that you should not delete the infected file instead you should just click quarantine! In the past i always delete all the infected files but it makes my PC unstable.. one day i read an article about deleting a virus VS Quarantining a virus! Quarentine is way better and safer than deleting a virus! source: [ http://www.worsttech.com/security/disinfect-computer-virus-spywares-trojan-1101817.html ] (MORE)

Viruses can intrude into your PC by different means. The leadingcause and source of most of viruses, spywares, trojan horses isinternet, especially downloads and E-Mail attachments. Othersources may include Flash Drive (USB), CD or any other device youconnect with your computer.
Viruses can get on a computer a few different ways. The most common one is through network sharing such as the Internet. Viruses are just programs that other people made to break/inhibit the computers that they infect. These programs get on your computer by being downloaded. After getting on a compu…ter, the program only needs to run for it to start doing what it was designed to do. Another way that a virus can get onto a computer is by means of a portable storage device such as a flash drive. However, unlike downloading from the Internet, the portable storage device must be physically connected to the actual computer manually and then run to affect anything. A third way is for the virus to be created on the computer that it's infecting. Coding for viruses can often be short, and not require any third-party programs to make them. To do this though, the virus creator must have firsthand access to the computer to be able to write the code and save it so that it can be executed. ----------------------------------------------------------------------------------------------------------------------------------------------- Virus get on your computer through flash drives, but especially the internet. They infect your computer especially when you download files, or just by visiting websites that are infected. (MORE)
Hi, generally speaking, the attack process can be divided into 4 steps: 1 Scan. 2 Start attack by some special tools. 3 Invasionã 4 To release virus, and register itself into the system files.

If you have AntiVirus, just do a system scan to find and kill the virus. I recommend Avast, if you need a good AntiVirus.
It's about the same thing as a human virus (in other word's it infects the victim,and in this case it's the computer)
Because just like viruses in humans, they can pass from computer to computer, being "contagious" in a manner.Plus it ruins your computer like it ruins a body
There are many effects of computer viruses to a computer, but it all depends on the type of virus. There are many types, including worms, malware, viruses, among others. A worm is simply a quine (self-replicating program) that does damage to your computer in a certain way. Malware is similar, but in…stead of self replicating, it is just the broad category of software intended to damage or disable computers and computer systems. Viruses are another broad category, comprised of programs still capable of reproducing themselves and usually capable of causing great harm to files or other programs on the same computer. A true virus, however, cannot spread to another computer without human assistance. Each of these types of viruses can do damage in a myriad of ways, depending on the virus. Online, you can be attacked by phishing, or a fake website that attempts to get you to enter personal data. (ie a fake facebook login page to get your login, etc) If this happens, then the safety of your online data will be compromised, and the hacker/cracker/attacker will have access to your accounts. If you download a virus, or a Trojan for that matter (just a virus that looks like a legit program) onto your computer, it can do just about whatever it wants, depending on the strength of the virus. A weak virus will probably not do much more than slow down your computer, disable programs, or attempt to lock you out of your own data. Usually, however, anti virus software is easily able to nab these programs and nip them in the bud; well before any lasting damage is done. (Some good Anti-Virus software is Norton, Symantec, or Siemens) A more powerful virus, however, can do a lot more damage. Many strong viruses will disable your anti-viral as soon as they hit your computer, and then place itself deep in your hard drive. Here, it can corrupt data, shut down ports, internet connection, regulate input and output from the computer, disable all executable programs, limit access to files and data, among others. Another scary component of viruses is the ability to avoid deletion. Strong viruses usually will know when the delete command has been executed on itself, and just before the command is completed, it will move itself, rename itself, and then send fake data to the computer, telling it that the virus had been deleted. When it moves, it doesn't just move around 'My Documents' either; it moves deep within the computer registry, hopping through files that you will probably never see. Once I got a strong virus that shut down all outgoing ports except one, which it then controlled to download 2532 different viruses onto my computer, just to make the situation worse. It then disabled all executable programs (exe's, bat's, msi's, etc) and disabled access to my data. It corrupted all restore points, and every time I found it, it moved itself. I had to wipe my drive and reinstall!! Good luck avoiding viruses in the future!! (MORE)
Viruses are quite easy to pick up when surfing the internet - some will get to you without you even knowing! Viruses can enter your PC when you download something, or when you accept an email from someone - essentially, when you knowingly accept a connection between your computer and another comp…uter (especially if you don't trust the person/connection), there is a potential for a virus transfer to occur.

It's impossible to answer this question. Over 50 websites are being created every second. 20% of websites have viruses.
The number of viruses that Microsoft computers get can not be counted, because once you are on the internet without a protection you are vulnerable to virus infections.
Download an antivirus program, such as Malwarebytes or Spybot if you want free versions, or Kaspersky, or McAfee if you're willing to pay. Don't use Norton. It's as good as a virus. Oh, and don't download porn. Prevention is the first step.
there are thousands of computer viruses, some more harmful than others. theres no way to tell because theres that many been made and some are been made useless
Viruses are specially designed computer programs (software's) to disturb the normal working / flow of the target computer system. Some viruses might have instructions to remove data from one/s computer and some might have the code to duplicate it for an infinite time. Also some might contain the log…ic for affecting system hardware. In each case, they interrupt the normal flow of computer working and might lead to low system performance or sometimes failure as well. (MORE)
