MachineLearning/Anomalous.100% while Chrome/Edge? Update (on a temp file)

[Wassolldasjetzt]

Hi,

 

Malwarebytes found a MachineLearning/Anomalous.100% detection on a temp file in my user/temp folder (C:\USERS\***\APPDATA\LOCAL\TEMP\BIT9D34.TMP). When i start windows the autoupdate for Google Chrome and Edge Chromium start at the same time about 5 mins after starting Windows. At this time 2 temp files with similar names apper in the user/temp folder. I tested it several times and always got 1 detection.

 

It seems to come from Google Chrome auto update. Because when i manually updated Chrome via Settings -> Help -> About Chrome other temp files appeared and the temp file generated by Edge auto update wasnt detected as a threat. Google Chrome updates from 87.0.4280.66 to .88.

 

Ill attach the log. Is there another way to submit the detected file other than posting it here? I dont know if theres any sensitve data in there.Malwarebytes.txt

Sry, too tired to find the edit function (if there is any).

 

Forgot some things:

The detection was no real time detection when the temp files were created. I did a thread scan just when those files were created. Bad timing, hm?

Im also using Kaspersky Internet Security. But this shouldnt have to do smth with it.

I repeated the process again. I got 2 temp files again. I did a threat scan = 0 detections. 

Using Windows 10 Home, 19042.630.

[cli]

It may have fixed itself in the meantime. You can PM me the file, if you'd like.

I still get a detection scanning the old temp file tho. Ill send you a PM.

 

Im still very much interested if its a false positive or if any damage could have been caused by this.

Not tired anymore - still cant find a edit function.

 

Anyway ... If another poor soul had the same problem as me last night and gets to this post via search: i got the information from cli that it was a false-positive. It seems to be resolved now.

 

Thx for your quick response.
