What I mean is that MSE (Microsoft Security Essentials) is really good. I moved my systems to it despite the fact that I still have a valid Norton IS 3 systems license for the next 2 years. It is light, non-invasive and caught a trojan 30 minutes after installation when I was downloading something from the Broderbund site (which I think is a reputable site). The trojan must have been trailing my download - like the submarines did in WWII.
PS: richc46, thanks for interpreting me - sorry for the shorthand style post which is usually not my style.
I also draw your attention to this easy option: Safe surfing with Sandboxie - very, very easy
Avira works well with W7 also, I have it running on one of my systems at home and as far as I'm concerned it's on par with MSE's detection rate.
However, if you are referring only to Avira Antivir Personal (free version), then I would suggest MSE as the free version doesn't include spyware/malware protection.
You could use Avira (free) + MalwareBytes/SuperAntiSpyware/SpywareBlaster etc., but the real time scanning in MSE is probably still a better option.
just my 2c :)
