Recent threat alert for 'Trojan:Win32/Vigorf.A

Hello, I recently got a threat warning on my Razor laptop for ‘Trojan:Win32/Vigorf.A’  from the Microsoft Defender.

The laptop warning indicated the following items is affected ‘file:C\Program Files (x86)\Razer\Synapse3\Service\Razer Synapse Service.sys’

When I run a scan on the laptop it then says that no threats are detected - it asks me to restart which I do, but after restart the warning pops up again from Microsoft Defender.

I have tried to quarantine / delete option in Microsoft Defender, but the threat comes back.

I have done a Google search on this Trojan name and some forums are saying its a false positive connected to the fan app?

I had to replace the battery in the laptop (purchased May 2022) after it overheated / deformed and bust open the casing of the laptop in June of this year.

Would these 2 events be connected?  Is this Trojan a false positive and coming from the system / app that controls the fans?

I am not very knowledgeable on hardware / software - I use the laptop for CAD, not gaming because of the rendering programs that I use.  I do not download programs regularly, I allow the laptop / Microsoft / Adobe / CAD programs to follow their automated updates.  Not sure how I might have triggered this situation but any help/ advice would be gratefully appreciated.

Thankyou.

As you’ve mentioned - false positive.

Issue is not connected with battery replacement.
