There are a few things I think it would be wise to do.
The situation with your AV is not good, because there should be at least ashServ.exe running in addition to ashDisp. So basically I think you are unprotected.
-Clean your temporary files. Use the inbuilt disk clean, Ccleaner (by Piriform) or ATF cleaner (by Atribune.) (If you use these be carefull not to tick stuff to clean that you may not want removed, for example,"menu order cache", or "wipe free space" [Ccleaner]). The inbuilt disk clean utility will do.
-Please download MBAM http://www.malwarebytes.org/mbam.php
or Superantispyware http://www.superantispyware.com/download.html
and save it to your desktop (or a convenient folder).
Install it, update it, and run a quick scan, and then advise what (if anything) is found.
-Download the Avast uninstall Utility http://www.avast.com/eng/avast-uninstall-utility.html
and if you don't have a current installer file for Avast antivirus, download that too. (The link is for the Home edition) http://www.avast.com/eng/avast_4_home.html
-Disconnect from the internet, right click the tray icon, select "program settings" then "troubleshooting", and disable the self-protection module.
-Right click the tray icon, select "stop on access protection".
-Uninstall from the control panel. Be advised you will lose all program settings and anything in the vault.
-Run the Avast Uninstall Utility. Reboot.
-Install avast antivirus. You should skip the boot scan- it takes a while.
See how that goes.
