Best Free/Paid AV.

I used bitdefender 2010 paid, but it sucks. Now im using avast and I dont like the adverts. Anything else besides these?
Im open to free and paid software. What do you guys use?
Also, anyone here use Linux instead of windows. I love Ubuntu, but Windows has all the mainsteam software. -_-
Ubuntu = Customizable interface, no viruses, no firewall, low resources, open source, bottom line better.
Windows = Viruses, spyware, hackers, all that bad shit, mainsteam software, cleaner more developed look

 

Personally, Microsoft Security Essentials which is free and really good. If your willing to pay for it, I'd recommend Kaspersky or Avira.

 

I recommend Kaspersky as well its a really good anti virus program.

 

I have a year of paid Norton lying around here somewhere, but haven't been bothered to install it yet. I heard it's good.

 

Norton sucks. It uses up all your ram and will attack any false positives.
