Avast made my pc slow, please help

Avast Free Antivirus / Premium Security
21

The problem was caused by Avast, since my computer was working good before installing Avast, After installing Avast my computer started working so slow

22

Not precisely. You’ve installed two antivirus at a time. You’ve used McAfee and AVG, so maybe the problem is not on avast anymore as you’ve fully uninstalled it. Why don’t you find the solution of your problem on McAfee leftovers or even on AVG?
How can we help you right now if you’re not using avast?
Sorry for the inconvenience, but there is nothing we can help further…
Did you try AVG forum for help?

The problem is not Avast anymore, I know that because it has being installed. But Avast made that problem when I installed it, so whatever happened during this process I need to fix it. AVG and Mcafee should not have anything to do with this since I had both running at the same time before with no problems

An understandable, yet incorrect take on this issue. Avast didn't make the problem. You did by having more than one AV installed. The installation of Avast maybe brought it to a head, but something like this was always going to happen, sooner or later.
  • Save the full installer file of whatever AV you want to use on your hard drive.
  • Download the uninstall/removal tools mentioned earlier in the thread, for McAfee and AVG.
  • Go offline. Disconnect completely.
  • Uninstall both AV’s (one at a time) from the control panel.
  • Run each uninstaller in turn.
  • Reboot.
  • Run a new install of the AV of your choice, follow the various prompts.
  • Check the Windows (or any other) firewall is turned on.
  • Reconnect to the net.
  • Update your AV.
  • If AVG (I’m guessing that’s the one you’re going to install) refuses to update, go to the AVG forums, search for that problem (there will be literally thousands of search results) and apply one of the suggested fixes. The normal fix is to wait until the servers aren’t overloaded.
    I might be doing AVG a dis-service; up until recently, slow/ no updates was a common ssue, since the release of AVG 8. Maybe things have improved a bit, don’t really know.

[edited]= missing step included.

Sooner or later, conflicts…
avast installed and uninstalled lefts nothing behind to mess your computer.

Thank you! I’m going to try this. At this point I’m trying everything to get my computer back the way it was before, its very annoying not to watch videos and wait more than 1 minute to boot, etc lol

You will love Windows 7 when you get a system capable of running it and I have set to do a cold boot.

My old XP Pro system takes less than a minute to boot as well.

[size=10pt]Yay I fixed my laptop!!! and you will never believe what the problem was :slight_smile: it was a coincidence, the problem kick off when i installed Avast so I though Avast made the problem ;D[/size]

What was the problem?

31

Cooling fan, it was dead. I kinda tap it a little, blow on it and started to work again, I know I have to replace it now. But since then my pc is working fine!!

32

Laptops are notorious for sucking in dust causing fans to cease up.

33

Yep, well at least I know now that, another cause of laptop working slow and cpu at 100, may mean that your cooling fan is dead :slight_smile:
