Virus

of course its possible, you can view a website because your browser translate a script in a webpage to be displayed in your browser. Sometimes this script contains a dangerous script that can be harmful for your computer, like installing unwanted application, downloading malware or something like that. We can't see what actually hiding behind a webpage(its script). Usually i am using a NoScript addons to block all scripts in a webpage that i don't trust. It even better than antivirus because its directly stop all script to running.

well . .while using websites..there is constant exchange of data goingon. .and hackers post their malware of spyware roaming around..and its unlucky..u get one and ur computer getting infected..

There are many ways in which a website can download malware (that is, trojans, viruses, spyware and such things) to your PC without you realising until it is too late. The ONLY safe solution is to install a good Antivirus software and to keep both it and Windows up to date with automatic updates. There is only one way of making sure that your computer is 100% safe and that is by not switching it on at all! However, a good antivirus software will protect you against practically all of the malware you are likely to encounter.

a lot of ways that virus can infect your computer from a website.. by viewing picture, by opening unsecured site, downloading picture, music.
