How do viruses attack your computer even when you're not surfing a dangerous website?

Lately, my internet security system has been telling me that critical, high risk attacks have been blocked. It happens about once a day. I thought that viruses only attacked your computer when you were surfing untrustworthy websites, but I haven't been on any sketchy sites recently. How do viruses attack your computer when you aren't going on any out-of-the-ordinary websites? How can I prevent viruses from targeting my computer from this point on? Thanks!|||You could have downloaded something which installed itself and then waited to do something. Some virus' are created like time bombs. They wait for a specific date and time and then attack the computer. There are also virus' called a "back door," which literally means that it installs itself quietly and unobtrusively and then opens a port thru the firewall (that is why it is called a back door) and then silently communicates with an external source who steals your private information without you knowing it. It is also possible that you installed something from a floppy disk, CD or DVD that had a virus on it.





So what you need to do is make sure that you have your firewall set properly. You also need to get into Safe Mode and run not only virus scans but also malware scans. A couple of good antimalware freebees are Antimalwarebytes and Superantispyware. It's best to install these programs, update their definition tables and then run them in Safe Mode.|||Computers have many "access ports" and your programs use separate ports to access the internet. Hackers know how to access these ports anytime your connected to the web. Like going to suggested websites for free help and upload things via activeX controls. Some of your programs may access the internet even if you don't want them to. Your best bet is to get a firewall to "hide" your open ports to hackers and disable activeX. Firefox also has a script blocker for their browser. Norton's anti-virus will ask you if you want a program to access the internet.|||Your AV is probably detecting tracking cookies, Good AV programs will block tracking cookies when they see them and most all sites have them now. They just want to see what sites people are going to. A cookie is not really a virus but AV programs identify them as shuch.





OH what's the other guy talking about? "Best place to get a job". I think he may just want people to go to that site and get a virus or traching cookies.





Have fun
