I can’t able to update Virus definitions which is 120309-0.
When i click update, it fails — Last encountered error : The parameter is incorrect.
Please try running the repair function then reboot.
To run a repair navigate to remove programs and click on avast as to uninstall, on the popup you have the option to repair, click and ok, reboot wen completed.
Can you try to repair your installation?
Go to Control Panel > Add/Remove programs > avast! antivirus > Remove. Then choose Repair function in the popup window (Repair).
If this does not help, can you uninstall / boot / install / boot again?
When i tried repair. it said ------ Error processing packages.Please use full update. So i uninstalled.I deleted the setup before which i already had.So once again i downloaded and installed.Now everything is fine.
Go to know. Thanks for posting back.
