The paid for Premium version on the main pc and the free Personal edition on the second.
The paid for version includes adware/sptware definitions and active email scanning whereas the free edition has neither of those.
Email is covered in the free version though as any nasty that tries to run will be picked up if it tries to run.
One of the main reasons I like AntiVir is it has very low overheads....low memory use and does not slow the pc down at all......that's with both Vista and XP.It also has much much better heuristic detection (picking up new viruses not covered by the definition database) than AVG and Avast.
When using any free antivirus a good active anti adware/spyware program is a good idea..Spyware Terminator is very good click here
I've personally never liked AVG and prefer Avast but neither match Antivir in my opinion.
Agree with tullie here. I use AVG free and have done for some time and its kept me virus free. I was just saying on another thread last week that I haven't even seen a virus for about 18 months on my PC.
I'll stick with AVG, perhaps Antivir is better, the trouble is different companies, magazines included, do tests in slightly different ways so in some one particular AV program appears to be better than another but in the same month another company can say that another program is better.
