AVAST! v.4.7 Home slows down computer

[utah2004]

Hello,

A friend installed this software, then found that other programs seemed to be running more slowly.  If she right-clicks on the "a" icon on the Taskbar, then "stops on-access protection" will this stop Avast from running thus giving more CPU cycles to other programs?  Or will some part of Avast still be running?  If still running, is there a way to stop it entirely?  Of course I would only recommend she do this while not connected to Internet.

Thanks for any help.

Hello Clark

Yes "stops on-access protection" stops Avast.
But only do this when you are not on the net and only execute games or files that you know are safe.
Always check files that you have downloaded with avast before execution.
To reactivate click on "start on-access protection" this will appear in the same spot that "stops on-access protection" was.

Also which FireWall are you using because I found that Zone alarm can also slow some programs.

We need more information on your friends system because avast is relatively light on system resources when compared to other AVs.

What is the CPU, RAM, OS of his system ?
What other security based software does he have that might have an effect, e.g. Spybot S&D (TeaTimer), AdAware (AdWatch), SpySweeper, Spyware Doctor (StartUpGuard or OnGuard), PrevX, WinPatrol, ProcessGuard, etc. ?

Have (or did) he another AV installed in this system, if so what was it and how did you get rid of it ?

What is the sensitivity of Standard Shield, Normal is the default and usually provides a good balance between performance and protection ?

But only do this when you are not on the net.

I won't suggest this... you're connected, download an infected file, go off-line, then execute and run the virus...

To run avast faster but secure, set the Standard Shield to Normal level (instead of High) or disable/close other programs, not the antivirus. If you go off-line, you can shutdown the firewall safely.
