...organic chemistry confused me in the same way: everything has a rule, and every rule has an exception.
wrt oa av conflicts, i understood that one should NEVER have 2 oa antiviruses simultaneously operative because it will cause system lockups...
This is correct! But what I want to say is that resident protection of an antivirus and resident protection of an antispyware
are not exactly the same thing.
So is not convenient running two resident antivirus, like is not convenient running two resident antispyware!
But if you want (your choice of course) you can run
one resident antivirus and
one resident antispyware.
Like Rafel, I use too Avast and SpywareTerminator. Without any problem! They work very good together, on my system. And slowing down of system is minimal (very difficult to note it and my pc is not so new), SpywareTerminator is light on memory (only 15mb).
I use SpywareT above all, because it provide basic function H.I.P.S. and resident protection antispy, a good combination in my opinion, talking about a
free program.
