yes your ideas are right.@Van2r
If you read EULA of all AVs (only ClamAV is the exception), you will notice that all AVs have "privacy issues". If you play games online you will send a lot of info about you the moment you log or update the game (it's the same story as with AVs).
Also, what @jackuars said is true
it is more questionable than that to decide ! anyway i don't think websites and internet related thing are not from world of trust.
its all about money i just decided to stick with things that have less price and payments for me both in cash funds and my time...
for enjoying a game or music the time which mostly ruined by viruses and antiviruses although i never seriously felt to an infection still i spent too much time on many security programs... nothing can make me satisfy at this point.
before i write this post i had free version of avira, for no good reason it's service host processes started to jump up and down in both ram and cpu usage which negatively affected my gaming experience in an offline game...and now its gone i'm glad it wasn't an online game !
