Thanks, Alanrf, but the Quick Scan you are talking about isn't on my Avast program.
Tech, I appreciate the advice. I am not referring to Windows Tasks and I just downloaded the Avast program I am using yesterday. The version is: avast! 4.7 Home Edition. It was built October 2006. You are correct in stating that there is NOT a scheduling option in this version. However, in the process of registering for and downloading the program, which I did before I received my registration key in Avast's first email to me, I checked a box, located on Avast's website, requesting the virus scan to run at 3:00 am. At 3:00 am this morning it ran and when the scan was complete it tried to restart my computer.
I am experiencing a Windows XP booting problem. I am working on that problem, but I do not want my computer to reboot until I have it repaired.
Any further advice would be very much appreciated. I am going to go through some of the process of downloading again, just to see if I can find the exact wording in the scheduling box I checked. Maybe, I can find resolution there. If not, I will see if that scan runs at 3:00 am tomorrow. If it does. I will simply uninstall the program and reinstall it when my XP booting issue is resolved.
Thank you, again.
