No problem, but don't go yet... listen... I'll post few information in next few minutes... ok ? So, stay here please...
EDIT (few minutes later as I promised...
):
Start your avast! antivirus clicking on that icon you just created on your desktop. Go into MENU, or simply right click somewhere on avast! window. Go into SETTINGS, then choose COMMON (most likely it's already selected). Uncheck TEST MEMORY DURING APPLICATION START-UP. That will disable memory check each time you start avast! from system tray (blue ball icon with white "a" inside). Now, try to start avast! from there as well and see what happens...
However, if your program hangs during memory checking, that doesn't have to be worst thing that could happen, but it could be... just in case, it could be something related to some nasty virus sitting in your memory... your memory test should pass without any problems, especially not with hangups...
My advice: Go to HOUSECALL anyway and check your system online. Keep us updated what's happening... When was the last time you performed whole system antivirus check ? Do it ASAP for your own safety...
Cheers !
Btw, I'm Craftec with "C", not with "G"... no big deal, anyway...
