Bri,
This is difficult to say. Avast should not cause problems with your restore points, but any program can cause conflicts with others.
How long have you had Avast installed? Do you use the Home or Pro version?
Lets check on one or two things. Go into your System Restore screen in XP and see if there is a check next to Disable System Restore. (If you have not done this before, Go into Start, All Programs, Accessories, System Tools, and then click System Restore)
If this is checked, remove the check and restart the system.
Has Avast alerted you to any virus in the past?
Remember, if a virus appears on your system, and a Restore Point is generated afterwards, the "print" of the virus is stored in the system restore and Avast will want to delete just like the original virus.
* This is remotely the source of your problem, but we need to look into everything.
Ok...You said that you uninstalled Avast and everything is fine.
You can try reinstalling Avast, but this time, make sure that windows programs are not running. Use Ctl/Alt/Del to shut down all programs listed except System Tray, Explorer and any Avast file.
At this point it is my feeling that there was some installation error or conflict.
If you decide to reinstall Avast, restart the computer before running the program for the first time.....then keep any eye on your restore points.
By the way, I use Windows XP and both Home and Pro versions, and have not had problems with either one.
Let me know.
Good luck.
