Some other softwares such as hacking tools,  AOL4FREE.exe also contains virus. Just think twice before downloading from any unpopular torrent sites. Also some web designers intentionally make websites which contains virus. If you open those sites they will start their novel work and you will start banging your head. So use anti- virus having internet security option which will block the virus from that site.

WHAT IS WORM?

 

A worm is a sub-categorization of a virus. A worm contains a small computer program that can replicate itself. Like a real worm it shakes its way back and forth through a computer system or network until it finds its way onto the internet. Many worms have closed corporate America for some days. As these worms had generated large volume of incoming and outgoing e-mails, the e-mail systems of Microsoft, IBM and other large businesses had literally collapsed. Once the user connects to the internet the worm starts its action e-mailing itself to the user's family, friends, colleagues and any other e-mail address it came across on the user's system or network and the most important thing is that the user is unaware of this thing. Now can you imagine how dangerous it is for the computers???
