Subject: what anti-virus are you using ?

I used Norton till 3 years ago when I swapped to Bullguard mainly because Norton killed PC speed as you say :)

indeed.. bullguard hasnt been mentioned much here although iv read good things online also.
i dont see an issue with eset though so wont be switching from it anytime soon.
its good theres competition in the av market atm. theyre all gone fairly cheap and do offers every so often where they are 10 euro for the year

Indeed, competition (for paid and free) is very good.

I have been using Alwil software for about 10 years and I think I won't change it for anything else in near future. I am currently running on avast! Internet Security suite on my computer whereas I am using avast! Free Mobile Security on my Android. Though when I had some experience with free versions of avast! antivirus, I had some kind of bad feeling - I found it less powerful. But it might have been just my impression or it might have been already changed ;)
