Performance Test by Tune- Up Blog

not running any realtime antivirus but when i did, avast v6 was the lightest for me by a country mile from the 6 programs that i tested.

 

Where are the results of those? Do you mean doing it yourself?

 

Here a more reliable benchmarks test

but anyway some products are not as light as they claim when compared under limited resources.
Here the difference between products forced to be light and enginereed for performance quality.

 

Never knew about those, thanks.

Lol! This is what it said: "We’ve used a MacBook Air (2009, Core 2 Duo with 2 GB of RAM) for performing these tests."

 

They also label the last test as Avira when in fact all references in the review are for Avast!
