thanks.

lol, just had ared pop up with your licnese has expired. you have 718 days left please renew? bios and system dates all correct by the way. subscription also says active

Try a repair of avast:
XP - Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.

Vista, win7 - Control Panel, Programs & Features, uninstall a program, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.

You may need to reboot after the repair.

Can you first try another manual virus definitions update and poste either the full text of the error or a screenshot of the pop-up.

thanks the repair said unable to find some files. the only thing that changed was last nights windows updates. i ran the removal utility and installed fresh it fine now. wonder what happened??

You’re welcome.

Hard to say what happened, it isn’t unusual for corruption to occur on systems, though this was reported as missing/unable to find (so a bit weird).

Main thing is that it is fine now.
