WARNING, DANGEROUS BUG !! 5.1.864 is not scanning anything

[fnukyguy]

I have updated from avast free 5.0.667 to 5.1.864. I did this by clicking "update program" under maintenance.
I have three shields running (file system shield, network shield and webshield)

file system shield and network shield is not scanning anything.
file system shield says "files scanned / infected : 0 / 0"
network shield  says "connections scanned / infected : 0 / 0"

webshield works though
 the eicar test files are not picked up by the file system shield...

Ive tried rebooting several times,,,

any ideas?


Windows 7 ultimate 64-bit, no other security software running, intel i7 920 system


*UPDATE* : I uninstalled avast, rebooted windows and did a clean installation of avast 5.1.864...now it works normally.
looks like doing upgrade from a previous version is broken somehow?

I'm also having this problem.

Can you provide a link for 5.1.864 version? Can only find on for 5.0.667 on the site.

Thanks very much, should probably have looked on the forums a bit harder. All seems to be in working order now.

this is quite a serious bug in my opinion...

I wonder what caused it...

Im glad I clicked the "real-time shields" and saw the "files scanned 0" indicator, otherwise my computer would have been vulnerable without me knowing it.
Avast was reporting "Secured. your system is fully protected" when in fact the file system shield was doing nothing.

I suggest to re-install avast from scratch.
I had this problem with a beta build before but solved by scratch install.

This is annoying. I've had such problem during beta test which was later gone when i re-installed avast! so i couldn't reproduce it. I suggest you re-install avast!, that will fix the problem for sure. But i agree, it's problematic because avast! is showing that everything is fine but in relaity it's not scanning anything.

i also having problem with this..but after that when i remove the 5.0.677 & done a clean  install of 5.1.864 then my problem solved

I have this problem too.    

I have updated from avast free 5.0.667 to 5.1.864. I did this by clicking "update program" under maintenance.
file system shield says "files scanned / infected : 0 / 0".
The avast tray icon never moves when I open programs.

edit: I just fixed it by uninstall/rebooted windows and did a clean installation of avast 5.1.864...now it works normally, but I might not have even noticed the problem if I was not reading this forum! I have another PC with Win XP, it updated fine, maybe it is just a problem for Win 7 64 bit?

Windows 7 Professional 64-bit, MBAM Pro security software running, Intel i7 950 system

I noted this problem in the beta forum- I installed the very last beta over the stable release and ran into this issue.

This seems like a serious problem indeed since it doesn't seem to be an isolated event.
Maybe it would be a smart idea to stop the auto update and investigate this further before too many users are affected. But there doesn't seem to be any particular rule for this problem to happen hm.

Do you guys maybe have 64bit Windows?

Yes, Windows 7 x64 here- running AIS.

I'm also having problem as well on my current system XP Pro SP3 lucky for I've clone my last backup before the new version came out so I'm back to Avast v5.0.677

Also I'm getting a lot of freeze up :'( on v5.1.864

[firzen771]

hmm, using the built in updater i didnt get this problem, each of my shields seem to be working fine.
