I have AVG Pro installed on my three computers it seems to use so much memory that my computers slow down, the fans run constantly, and the laptop has become useless for anything other than running AVG.  They all run Windows 7.
I have tried shutting down processes through the task menu, but they do not seem to be using all that much memory.
I have also tried shutting down uneeded programs, registry cleaners, pc tuneups etc.
Any suggestions other than new computers?
