How do you know if something your downloading has a virus?

Question

from anywhere from the internet or limewire, a free pogram ( that doesint take much space ) that will tell me if something im about to download has a virus.

also, how do you make sure your computer is safe and protected agait spyware and your privacy cannot be viewed by anyone.

please answer this question. infact if you give me a really good answer, not only will you get 10 points, but i will ask a ramdom question ( i will tell you ) and might give you another 10 points on that question on purpose.

thank you.

Answer 1

well anything you donwload from p2p programs has threats mostly .exe files you should scan wth an updated version of your antivirus before installing you will also need anti spyware running all times like Ad aware 2008 and Spybot S&D

Firewall is also a must like Comodo or Zonealarm
