Help with Avast! service being turned off

[Ziggurat Vertigo]

Hello, I've downloaded Avast and after I turned off my computer for the night and came back today, the screen for the status tab says that I'm unprotected; below that it says that the Avast Service is off. I click resolve all and after about a minute this window pops up (I attached it to this post as it tells the tell better than I could). Regardless of which I click, nothing happens. I'd appreciate it if someone could help me get this working. The only other anti virus software I have installed is MSE. Thank you!

First thing is "uninstall" MSE. Having two resident a/v's is a really bad idea. See http://www.bleepingcomputer.com/forums/t/260844/two-anti-virus/#entry1441638

To uninstall MSE you will find instructions here http://support.microsoft.com/kb/2435760
By uninstalling MSE using these instructions you will also uninstall the MSE drivers.

Then do a clean install of avast using this http://files.avast.com/iavs9x/avastclear.exe. You will be directed to reboot into safe mode...click "yes"
Reboot
Re-install avast.
Reboot and register or insert license.

Never ever have 2 antivirus running at once... it's disastrous

Para-Noid's link is useful and informative.

I'd recommend a clean install (same as Para-Noid mentioned but more step by step)

1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition

Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn't)

Avastclear : http://files.avast.com/iavs9x/avastclear.exe
Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

2. Uninstall Avast by control panel  [If you don't have Avast in control Panel go to #4]
3. Uninstall in safe mode using Avastclear.
4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn't) - reboot.
Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle.. if so, uninstall it and reboot.
5. Install the version you downloaded.
6. Reboot.
