hi and welcome aba
can you give me some general info of your system ?
What O/S ?
How long have you had Avast!?
Has it ever completed a scan?
Did you install the program using Admin Account?
this should help us track your problem down
Info about my system:
Win 2000
I have been using avast for two years,
In the past many times it completed the scan, but recently when avast starts scanning; it shuts down after a few seconds of scan.
Never had this problem before,
I have Sygate firewall.
I installed the program using admin account,
And one more thing, within past two weeks the only software I installed was Microsoft Anti spyware, which soon afterwards I uninstalled it because I thought it might have some thing to do with the avast malfunction.
Many thanks for your reply.
