Avast detected Windows Update as malicious
« on: August 12, 2014, 07:37:33 PM »
Latest Avast Free. 

1 update failed on today's patch Tuesday, believe it pertains to Microsoft.NET Framework.  Was put in chest.  I cannot remove it, exclude it or anything.  Just stays there in the chest.

Win3:Evo-gen (susp)

Please fix it asap!  Thanks.

Same here... avast really out did itself this time.

Ant then you know if you look into the results and look under virus, it says "no virus".  Between this and the "threat detected" bug and the numerous bugs that have gone unfixed with the software ever since 9 came out and the serious silence from Avast on any issues and no new versions in a while... and the poor av comparative scores... I really have to start wondering if this software is even doing anything anymore.

In normal situations I would work with this. However this involves an update for .NET 3.5.1 for Windows 7.
The files in the chest are all .tmp files aka unzipped files to be used for the eventual update itself.

So normally good advice to report it as you wrote but this time it involves 51 *.tmp files. Hardly reportable as it is.

Hi CaptainLeonidas,
   What does that mean; should we just wait for Avast! to update their definitions?

Yes Avast needs to update their defintions... this is not applicable to virus's and worm's section... this is a major bug

I'll wait for the definitions update...but, apologies if this is a silly question, is it okay to be online without the failed Windows Update? (All the others installed successfully.)

i would say yes ..... Microsoft could have waited with the release and you would not have known about them

You're fine... you should actually be able to just take your computer offline, turn off avast, hit try again on windows update (the files have already downloaded) and it should install correct?

The update can be re-installed.
If it fails to show you can always "trick" Windows into rescanning for updates.

Run -> type: Services.msc -> Stop: Windows Update service -> delete the update folder: C:\Windows\SoftwareDistribution -> Start: Windows Update service.
Recheck for update as always.

PS: You will loose your update history
