Aha....
But, Avira free is anti virus only. So you still have to find something else to run your anti-spyware and stuff.
AVG version 8 free has antivir and antispyware, in one package.
This will definitely explain why it's also a bit slower, it's heavier. Avira is light and nimble, like a TVR. AVG is more like a Corvette Z06.
Both are huge fun, but the TVR will get around a track quicker.
