Hi. I have a big problem with my computer. I am using two Hard drives of different sizes, 320 and 80 GB respectively. The fisrt one is installed Window 7 and the other Window XP. The hard drive which i use mostly is the 320 GB one, the other (80 GB) mostly for storing important files. I have installed AVG antivirus with the first Hard drive and the other hard drive I have not yet installed any antivirus, but I am thinking of installing Quick Heal antivirus, not so long. I just want some advices about how dangerous, or is it right to install two antivirus, in two different hard drives in the same computer. I would be glad if answer my post. Peter
