Hi everyone! Today I had a power failure in my district just when my Avast! 5.0.462 Free was updating a virus definitions and my Windows XP shut down. And then something went wrong. After I rebooted my machine and opened Avast’s! GUI to check whether it’s virus definitions has been correctly updated or not, I saw that they’re outdated: (!) 100309-1. I thought it is normal situation given that this power failure, so I clicked an “Update” tab on the “Summary” screen next to this outdated virus definitions. And after a while I had an unpleasent surprise: Avast! said my signatures has been already updated (100310-0), but on the “Summary” screen it was still: (!) 100309-1. Next what I did was rebooting my machine again, in the hope this would fix this issue. Unfortunately, it didn’t help. I have also tried “Repair” with “Add or remove programs”, but it has failed too. I was about to wait and see if the next auto-update of the signatures would fix this glitch, but I thought: there must be some workaround! I had an illumination ;D. And what if I reboot an Avast! itself, without rebooting my OS? Bull’s-eye! And this is what I did: first I disabled an Avast’s! self-defence module in Settings - Troubleshooting and I shut it down completely via “Services” in “Administrative tools”. Subsequently I launched Avast! again and enabled self-defence module. And after these steps I had this nice looking (V) 100310-0 on my Summary screen :D. Important: follow these steps without rebooting your machine! I hope my incident will serve people with similar issue, cause you never know when the lights may go down ;). Best regards to all.
I tried this when I had a similar problem - only it didn’t work on my machine - the report says my current version is 100811-2, latest version is 100812-0. When I update manually, all seems ok, it says “definitions up-to-date” , but the summary shows the same error. Which is correct? and is the definition file up-to-date or not? ???
Edited. Sorry.
My apologies, I am not familiar with the “etiquette” - I was not aware that a reply represented “hijacking”
Sorry. It was my fault, not yours. I’ve misread your post.
Try a repair of avast. Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow. Reboot.
