« on: January 17, 2011, 11:57:14 AM »
Hi, I am setting up a new Win7 64 PC and avast! installed fine and updated correctly. However, when I try to update now, it fails withthe invalid file signature message. Any suggestions please?

Hi

for me the same: my AIS 5.1.889 @ Win7-64bit comes back with the "Update fails: invalid file signature" when it tries to update to 110117-0. All updates before that went fine.

Funny: my WinXp-32bit updated correctly.

Could it be a 64bit thing?

Thanks for your support.

No problems for me and I use a 32bit system.
avast! just updated automatically this morning and the current definitions are 110117-0.
Anyone (except who already posted) with 64bit system is having the same problem?

Now whats up with invalid file signature(auto updates)!!!
Lets get this corrected please ::)

One minute you have to uninstall every part of avast to get the new version to work

next it wouldn't update even with permanent connection to internet ticked had to be now use internet explorer settings

Now it won't update as its invalid file signature(win 7 64 bit), whats next?? ;D

Your older versions worked good for eons ;D

Sadly, this once great program is getting very unreliable. I cannot complain though as it is provided free.

Vista Bus 64
Program 5.1.889
Virus Def version 110113-0
 Same here too, Invalid file signature. Setup will terminate

This started "several days ago" (if I could be more specific, I would) but it was at or about the time Avast Updater installed the update program as part of auto updates. I only today uninstalled Avast, reinstalled, tried to updated and Googled the error did I come across this forum and thread

 ??? :'(

Unreliable? I've been using Avast for years and it has yet to either fail or disappoint me. As a matter of fact, the problem with this update is -as far as I can remember- the first I've ever seen.

So for those having problems updating - don't worry, don't dispair, don't go mad. Avast! will fix the definition file soon.

-- Update: as a matter of fact, it has been fixed now! I just manually updated succesfully.

Appears to be corrected
Mine just did an auto-update without any problems
