Unable to install avast

General Topics
1

I’ve been using avast since i bough my laptop (almost 3 years ago). Since then, I’ve had no problem using it. But 4 days ago, I saw a message telling that my laptop didn’t have any antivirus. I deinstalled avast and downloaded the latest version. When I double click on the .exe for installing avast, there is a message asking if I allow the program to make changes in my computer. I agree and, after that my laptop acts as if nothing had happened and doesn´t do any action to proceed to install avast. After a while I do the same and, again, nothing happens. I also have to say that since the antivirus “deactivated itself”, my computer has been running significantly slower.
I appreciate any help to solve this problem

Sounds like you are experiencing the bug in the Windows security center, I suggest you follow these steps:

  1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition.
    Here are the installer links. Note: You need to be ONLINE during this install.

Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

  1. Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #4]
  2. Uninstall in Safe Mode using Avastclear.

    If there is anything related to Avast with a yellow triangle then uninstall it (highlight, right click) and reboot.
  5. Install the version you downloaded.
  6. Reboot.
