Hi guys,
Thanks for the input.
I tried several products on several PCs I had through the years.
I'm now with Avast! home edition v4.8, which seems to do the trick for the most part.
I also have been using for a while now an addition that's called 'threatfire v4.5'
This, as far as I know is the newer approach to AVs. It tries to not count on an extensive DB of known malware, but rather monitors the behavior of different codes and tries to decide if it a good-code or mal-code. If it determines that it is mal-code, it will stop it and popup a window for you to decide what to do (remember/ not - an option).
So far it seem to have been of use with few false positives.
-The approach is now developed to overcome two main problems: (1) Taxing the RAM, (2) Zero alert infection.
-Now I'm more afraid from rootkit malware. Don't really know if there's a good way to prevent infection on that level.
Let me know what you think,
