avast slows my computer down

Hello I have a Dell all in one with windows 7. I installed avast on my system and now it runs slow. IT hangs up like its thinking. I thought there may be a lot of programs running in the background so I checked and disabled some start up programs. As it still ran slow I suspected the avast so I uninstalled avast. As soon as I uninstalled and restarted my computer the computer is no longer hanging up. Whats the deal? Thanks

Maybe your computer doesn't have enough resources to run extra programs.

What are you CPU and RAM specs?

It would have to be real dead dog of a computer to noticeably slow down because of a modern AV. I have an 462, 3200 Barton system digging thru internet all the time and can't tell difference when Avast free is running and when suspended.
Either that or it's not optimized at all and in disastrous shape OS wise. Most people do not need full, corporate versions of AV, they just have too much gong on that do nothing for a home PC. Free versions are quite enough. People think if something is labeled "professional" is much better.

Maybe Avast's active scanner would be the cause of a slow down. Did you find any viruses or malware, while avast was installed?

On my rig, Avast is only using 2.8 mb of ram, and no cpu usage, unless I run a scan. Your system specs, would help as 901-Memphis asked. msconfig is your friend.
