File Exceptions not working
« on: April 20, 2022, 01:33:19 AM »
I had the same following problem with avast so I upgraded to avast one and same issue.
When I try to open word or excel or a word or excel file it says we've secured winword.exe  because it was infected with win32:malwarex-gen(trj).
This began about 2 avast updates ago on all my computers. I get it back from quarantine and add exceptions all over in ransomware and the virus scan areas but when I click on word or excel I get the same error even though it's still in the exceptions. I have to go get it back from quarantine.
The only way to open word or excel is to deactivate avast.

Test the file at VT (https://www.virustotal.com) and post the link to the result here.

It would have been much easier just to post the VT link to the analysis.

sorry, didn't know if it would give you a blank page if I did that not the results.
Here it is....

No problem, it's just that the link gives more information, that link was from 20 days ago, so unless you refresh it it just shows the last scan.

I refreshed the scan - https://www.virustotal.com/gui/file/e7dc21f75eb5c709d315b3bc24c2453c259369d6e31508b4d6689bc5e12557b0?nocache=1
It still has the same three detecting it and strangely Avast isn't one of them.

I think part of this is down to this is a very old Microsoft file that isn't digitally signed.  Most old files like this (in that time frame) weren't digitally signed.

If it is in quarantine open the now send it to Avast for Analysis (images 1&2 below, click to expand) - In the remarks give a brief description of the problem - probably more important give a link back to this topic.

Your Ransomware exclusion wouldn't stop this alert, I don't think the exclusions for the 'virus scan areas' would work either as neither of these are responsible for the alert. The area it would need to be in would most probably be the Avast > Settings > General > Exceptions (image 3 below).
