guys, my friend said that, i can use 2 antivirus in my desktop to be sure that i am secure from viruses. at first, i guess he got a point there but i am not sure if his advice is recommended or not?

more advice pls

tnxThat's a bad idea.
Many AV programs are not COMPATIBLE with each other and this can lead to system instability or at worst leave Windows unbootable.
It is a much better idea to just have one good AV program installed. You can then use the online scanners many AV companies PROVIDE to get a second opinion once in a while.
Another great tool is VirusTotal. You can use this WEBSITE to scan any suspicious file you might receive. The file will then be scanned by 20+ AV engines.dude, thanks for your advice. now i know the risk of using 2 AV. is there a site that can rate all antivirus software with stability and performance in HEALING the virus?

anyways, thanks a lotHere's a couple of sites.

This will give you a well rounded protection arsenal provided you update and scan regularly.
