Is anyone having the same trouble as myself?
I noticed my pc keeps on running extreemly slowly and after trying lots of other things, i turned my avast off completely. The pc runs perfect without it… Does anyone have the same and if so, how do we resolve it? I have been happy with avast for a long time now and dont want to have to go back to my old one…I am also new today on here, so if i am in the wrong place etc… im sorry 
Hi, welcome to the forums.
What OS are you using? is it up to date?
What avast! version and VPS file (virus database) number, e.g. 0436-4 (see about avast!)
This forum will be fine for now as you/we haven’t established that it is a problem related to avast!
There can be many reasons why your computer runs slow and accumulation of program running in the background using system resources and adware/spyware slowing things down.
It would be best to use a program called hijackthis it lists everything that is running on your computer.
Download HijackThis.zip and check out the HiJackThis Tutorial, then post the contents of your log file here. If you need more help just ask.
Hi, thanks for that…
OS is xp home with service pack 2, all up to date… my avast is all up to date, the newest one…
i have ran the microsoft anti spyware thing, results nothing found… avast anti virus, nothing found…
it only seems to run slow when i turn avast back on…
here are the results of the scan i have just done with hijack this… maybe you can see what the problem is, i dont understand it all…
thanks, angie :o)

i have now fixed the ones you said, and i have done the repair on avast like the other person said… and everything seems to be fine now… so thanks a lot you two… much appreciated… angie
Yes, in fact that is why I came to this forum looking for solutions. I’m using a dell p4,512ddr and Windows XP, SP1. My default browser is FireFox except when I am forced to use IE. I have tried several different remedies but nothing has worked except to disable Avast. Every thing goes back to normal. This hanging up (slowingdown or crashing) started about a week or so ago after a large update from Avast. Help!!! ???
P.S. I have run a virus scan with avast and grisoft, adaware, spybot and have detected NO problems. I also use SpywareBlaster all the time and routinely dump the cache in FireFox and clean the disk once aweek all this is while using a dial up connection. :
Are you using AVG and avast at the same computer, at the same time (residents)?
negative, I use Avast while online. And when I check my computer I run Avast and AVG on seperate scans at seperate times.
So, you do not use the Standard Shield of avast! Only other providers while you’re online. Ok.
I’m using XP and Firefox without trouble :
Edit: cleared intentionally incorrect information.
Yes, this is exactly the same problem i had… Someone called xistenz on here gave me a tip… go to control panel, then add/remove programes, and then avast, and repair… it worked for me… its been running fine all night with avast all up and running fine too…
Try it and see…
Angie
Angie, thanks for the reply but I’m missing something. I go to control panel, add or remove programs and I have looked everywhere for something that says “repair”. All I can do is change it or remove it. what am I missing? Windows XP, SP 1
wllm55, look at my previous post here, then click on the Change/Remove button on “avast! Antivirus”.
Then scroll down the list until you find Repair:
Change → Uninstall → Update → Repair
Sorry… your not looking for ‘repair’… your actually looking in your list for Avast… click it, and then scroll down to repair, then click it… hope this solves it, as it did mine… Angie
Click the change/remove button, you will then be presented with another window, here you can select repair.

Gotcha, DavidR and Angie! I followed your instructions and repaired Avast. I will see how it goes, thanks for the help ;D
Yep! that worked. Everything is back to normal. Thanks for the help
