If there anything related in Windows Event Log?
All I could find in the Windows Event log is the following...
Under the heading 'System' it says...
"The Avast! Antivirus service terminated unexpectedly."
Under the heading 'Application' it says...
Application error :-

It's probably doesn't matter - but how much RAM do you have in your machine?
3GB of RAM. (OS is Windows 7 64-bit, processor is AMD Athlon 64 X2 5,200+)
P.S I tried typing 'QuickStartupMem' into the "Areas to scan" box of a custom scan and when I hit the 'start' button Avast crashed (red x on system tray icon).
Thanks for continuing to help me with this problem, it is much appreciated
