A guide on computer virus

This might be a difficult situation when you have loose your important data or your system remains in non working mode for a long time,restarts every time you start it or your email id sends thousands of emails per minute from your system without your knowledge.

This is simply the indication of presence of virus in your system.I am sure you want like the presence of a virus, trojan horse, malware, spyware in your system.So here is the guide that will help you in preventing the entry of virus in your system.Follow these basic steps they will help you in your fight against virus.


1.Install and run a good virus protection program. If the program is mainstream, it's good--McAffee, Kaspresky, AVG and Norton are pretty much the key players.

2.Since most viruses attack DOS, stay away from DOS. This means if you want a Microsoft operating system, run Windows NT (Win95 and Win98 are still DOS under the hood). UNIX and its variations (such as LINUX) are a bit more robust, but you may not find the programs you want.

3.Use freeware and shareware--especially games--with extreme caution. Many viruses and Trojans come bundled inside such programs. If you download such a program from someone's website, it's probably safe. If you get it attached as an e-mail or on a floppy that is making the rounds at the office, watch out

4.Set your CMOS so your computer does not seek a floppy at boot-up. This prevents you from getting the nastiest of the viruses/Trojans out there, because these have to load at boot time. Similarly, don't open e-mails with attachments you didn't ask for--these can load executables on your root drive and do similar damage.

5.Don't use pirated software. If someone will sell you pirated software, do you think that person has any qualms about passing along a virus?

6.Set up your word processor to ask you before enabling macros. If you always select "no," you become immune to macro viruses--you can always enable the macro after doing a virus scan.

7.Visual Basic scripting was really cool when it came out. Now, the virus writers use it for their nefarious purposes. You need to disable script execution in your browser settings or risk getting a VB virus.

These will definately help you.For more virus updates and types you can consultthe BBC guide to virus protection.
