Oh my God...this was awful. I downloaded Avast, installed it, ran it on my computer, and in a matter of no time, my computer crashed. Avast ate into all my system and registry files, leaving me with no other option except to format the computer from scratch.

i have used so many antivirus,but i found avast 4 pro.is the best.

I have used Norton McAfee and PC Cillin
Avast is far superior to them

I think avast professional edition is the best and it protects your computer from virues a lot because i am also using avast professional edition and whenever i get any virus in my computer so it tells me that you have virus in your computer and it also tells me that which virus is that so i can easily remove that virus by using avast professional edition.

It's really good and it helps me a lot. I like it and it's better than norton antivirus that i think because whenever a virus come in your computer so avast professional antivirus will tell you that you have virus in your computer and it will also tell you which virus is in your computer so you can saftely delete the virus by using avast antivirus.
