F-Prot version 3.16f – 85.14%
In another review Norton is stated one of the worst applications that slow down your computer. And I agree, it IS free antivirus slow. I`ve seen some other results where at norton antivirus free top is Dr.Web. Of course the test is not precise, as it is always sponsored by some company (this one really looks like AOL and Kaspersky sponsored one, it`s too optimistic 99.62%).Kaspersky has created a large community around the world to support it. For now at work I have Norton Internet protection suite 2006 (I`m without admin privilegies) and on my laptop I have deactivated Dr.Web and activated AntiVir, because one nasty virus Dr.Web couldnt catch and Antivir just detects it, but still cannot cure.
