Trojan "Win32/Tnega!MSR" found by Windows Defender - aliases used by other antiviruses?
Does anyone here know the alias used for "Tnega!MSR" by other antiviruses, or can point me to a resource so I can find it out myself?
Use the VirusTotal website.
They have a lot of information on all the various names for this malware here
For example, Defender calls it "Trojan:Win32/Tnega!MSR", ESET calls it "Win32/RA-based.NJV", et cetera.
I don't have the rep to place a comment on hft's answer, but Process Explorer (from Sysinternals, owned by Microsoft) can connect to VirusTotal to check if any running processes are malicious. To my knowledge it can be used to check any process which Process Explorer sees. HowToGeek has a relatively modern overview of it as well here
