Welcome to the forum. :slight_smile:

  1. What version of Avast did you have installed?
  2. What other security software do you currently have or did you have in the past on this machine including:
  • Antivirus (AV)
  • Firewall (FW)
  • Trial versions of AV, FW and other security programs
  • Other security software
  • If they were in the past, how did you remove them (the vendor’s uninstaller’s tool or another way)?
  1. Are your MS/Windows Updates (current)? Does your Vista have SP2 or SP1? If it only has SP1, please upgrade to SP2 first. Reboot.

Save a copy of Avast and save it to your HDD:

Did you uninstall Avast via the Uninstaller Tool before installing MSE? If not, please uninstall Avast using the tool:

  • Download the Avast Uninstall Utility http://files.avast.com/files/eng/aswclear6.exe and save it to your HDD.
  • Disconnect from the Internet at this time.
  • Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
  • If Step 4 fails, boot into Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool. Uninstall ALL versions/products of Avast on this machine one at time and reboot in between each uninstall.
  • Reboot.

Then you can uninstall MSE http://support.microsoft.com/kb/2435760/ and reboot your machine.

Install the newest version of Avast and reboot.
