@Admin,
Well let me mention my usage in internet :
Email checking, surfing in forums, blogging, browsing, chatting, downloading loads of stuff through P2P. Now P2P is the max usage from my internet. Now I am not sure which one to go for. Avira or Avast or AVG..!
However, I am considering to go for Avast + Malwarebytes. Any comments ?
from your usage, i would definitely suggest switching to ubuntu full time.
you won't have to worry about any form of malware. and you can still do what you do with the tools available on linux.
