Avast Free Antivirus / Premium Security

I have the latest version of Avast; and the latest version of Windows 7. Avast is causing crash on my pc.

On Sat 7/12/2014 1:32:09 AM GMT your computer crashed crash dump file: C:\Windows\memory.dmp This was probably caused by the following module: aswsp.sys (aswSP+0x664A9) Bugcheck code: 0x3B (0xC0000005, 0xFFFFF80002E88AC5, 0xFFFFF8800BB60400, 0x0) Error: SYSTEM_SERVICE_EXCEPTION file path: C:\Windows\system32\drivers\aswsp.sys product: avast! Antivirus company: AVAST Software description: avast! self protection module Bug check description: This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: aswsp.sys (avast! self protection module, AVAST Software). Google query: AVAST Software SYSTEM_SERVICE_EXCEPTION

It is CRITICAL you look in your system to see and make sure you have uninstalled/cleaned out any old A/Vs that may have been previously installed…even if they are gone you need to check. The nature of new A/Vs is that they are very intrusive in system and can be seen, or see others (even renmants), as conflicts.
Here is Avast FAQ on the subject: http://www.avast.com/faq.php?article=AVKB11#artTitle

After the above is complete I’d do a clean un & re-install of Avast…
Avast Clean Un- & Re-Install

  1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition.
    Avastclear : http://files.avast.com/iavs9x/avastclear.exe
    Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

Here are the Avast installer links. Note: You need to be ONLINE during this install.

…Now…
2. Uninstall Avast by Control Panel>Programs [If you don’t have Avast in control Panel go to #4]
3. Run Avastclear in Normal Mode and allow it to Reboot PC into Safe Mode to complete the removal process.
4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn’t) - reboot.
5. Be Sure To Check PC’s Device Manager…Control Panel>System Once Uninstall is Complete.
Make sure to show any hidden devices by selecting pull-down menu Device Manager>View>Show Hidden Devices
If there is anything related to Avast with a yellow triangle then uninstall it (highlight, right click) and reboot.
If you get an error just right-click & delete.
6. Install the Avast version you downloaded.
7. Reboot.

3. Boot to Safe Mode and Run Avastclear.

Simply run avastclear in regular mode and allow it to reboot into safe mode to complete the removal process. :slight_smile:
