Windows 10: Windows Defender repeated threat warnings despite repeated scans

My laptop running Windows 10 has been giving me repeated threat warnings for the last few days. This started after I bought a new computer and signed it in to the home wifi network, but I have not directly connected the two computers.I get a notification from Windows Security that there are threats found. I then go through the "current threats", select an action, and tell it to run. Windows Defender does its thing, then says there are no threats, but then at some point the same warning start popping up again. I have fun a full scan multiple times and run Microsoft Safety Scanner a couple of ti

:)

 

Windows defender Trojan repeated warning

Every time I restart my computer I get a new threats found alert from windows defender. Scan history in Windows Defender Security Center shows in Quarantined threats "Trojan:JS/Runas Severe". This presents the option to Restore or Remove. I selected
Remove, but next time I restart I get the same warning. If I look at the details in Windows Defender Security Center I see "This program is dangerous and executes commands from an attack." Affected items is listed as a file in C:\users\[my username]\AppData\Local\Microsoft\Windows\INetCache\IE\[6
letter code]\deploy[1].xml. The folder C:\users\[my username]\AppData\Local\Microsoft\Windows\INetCache does not exist on my computer so I am unable to look deeper into this. The 6 letter code is different for each warning. How do I remove this threat/problem
permanently so that it does not give a warning each time I restart.

I have not yet tried independent scanners or the removal guide from the first post.

I am not sure how or what a good way to access the file is to submit to virustool.

The location for affected items listed by Windows Defender Security Center C:\users\[my username]\AppData\Local\Microsoft\Windows\INetCache\IE\[6 letter code]\deploy[1].xml does not exist. Presumably this is because Windows Defender quarantined this. I
presumably would need to restore this to get the file back but I am reluctant to restore something Windows Defender identifies as a threat (for obvious cautionary reasons).

The malware removal guide has an overwhelming amount of information and requires downloading, installing, accepting security warnings etc for 3rd party software that I am not familiar with so I am proceeding cautiously and incrementally and trying not to
make getting rid of a once per restart annoying message a too time consuming project. I am scanning with Malwarebytes now as a step in this process.

I don’t think you copied down the correct name of the malware.



But - suggest you see the following…



Since you are seeing repeat detections, the malware may be in your temporary internet files.



Try emptying temporary internet files, restarting the computer, manually updating Windows Defender and running a Quick Scan.



Any new browser extensions that need to be removed/disabled?
