Welcome to the forum. :slight_smile:

You may want to try cleaning your machine with something like CCleaner, a free system optimization, privacy and cleaning tool. There is a Slim version available as well at http://www.piriform.com/ccleaner/builds – 4th option down. It removes unused files (cache, temporary Internet files, etc.) from your system, allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history.

Then reboot your machine.

If this does not fix the problem, then try an Avast Repair:

If this does not fix your problem, then you may need to provide us more information about your machine:

  1. What is your OS, 32 or 64-bit?
  2. What version of Avast did you install?
  3. What product of Avast did you install? Free, Pro, AIS?
  4. 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)?

And you may need to provide us with a mini-dump while you are having the problem:
Here is additional information on how to invoke a memory dump file: http://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=71.

Please, zip and upload the C:\Windows\Memory.dmp file to this anonymous ftp server and name it uniquely giving us the name of the file in this thread: ftp.avast.com/incoming. Avast will analyze it and respond back to you in this thread.

If you are having difficulty with dump file:

  • Using Internet Explorer, Connect to the link and drag the file into the Right pane and drop it, that starts the upload, you don’t have read access to this folder, so you won’t be able to see it once uploaded.
    Or

  • Upload it using the Run command-line in Windows: Windows Key + R (to get the run box), copy and paste this:
    Code: explorer ftp://ftp.avast.com/incoming

    and drag the file into the window, from another explorer window.

Let us know what fixes your problem and if you have any questions. Thank you.
