Hi,
I don't want to hijack this thread, but this is a "me too!"
I am running Windows 2000, recently updated using Windows Update.
I tried both of your suggestions, however neither resolved the problem. Even after reinstalling I had the little red symbol in one corner of the Avast icon.
I can start the service from Control Panel>Administrative Tools>Services, where it is set to start automatically.
This isn't actually the first time this has happened to me. It generally seems to happen after I have installed new software that operates at driver level, such as a new firewall. On this occasion it occurred after I installed a virtual printer (PDF4Free, please see
http://www.pdfpdf.com/pdf4free.html )
On previous occassions I have uninstalled the program which appears to triggered the problem and reverted to my last OS backup, which normally solves the problem - though I have even had it occur after restoring a backup. Sometimes having left an explorer window open at shutdown is enough to create this problem at the next start up.
Occassionally restarting the computer will solve the problem, but normally not.
I'd like to solve the problem properly this time, as their seem to be a growing number of pieces of software that I can't use because of this issue.
Is there anything more I can do?
Thanks!
