Here's the most simple ways protect your computer against virus:
- Separate your hard drive (C) in two different partition (C and D). This should be done before installing your operating system. If not, some program like partition magic could do it without formatting your computer. This way, you can save all of your valuable content to the D drive and install the potentially dangerous program on the C drive. If anything happen, you can always format the C drive without losing your content. You might want to save the downloaded program on your D drive and install it on the C drive. This way, if you get a virus and have to format, you'll erase only the C drive. So not only you'll still have all you multimedia files but you'll be able to reinstall all your "healthy" program instantly.
- Never open a program without scanning with a good antivirus first. Every program that you execute on your computer as to be analyze to make 100% sure they don't contain any virus. Do not worry about picture, audio and video files. If the file you want to scan is smaller than 5mb, use virus total to scan it. This web site is completely free, very efficient but unfortunately cannot scan bigger files. For any file over 5mb, use Anti-Virus Elite. A user friendly, extremely efficient antivirus used by 47 million people, the best tool keep your computer clean at all time.
- Beware of peer to peer software like limewire, morpheus or shareaza. Not only do most of these type of software contain spyware in the program itself, but almost the majority of the files found using these software are infested with all the possible virus you can imagine. Take all the required precaution if you decide to use them.
Have Fun!
