Possible virus in .scr file. Is this a false positive?
A year ago I downloaded some retro screensavers from Windows 95, including one called "ssstars.scr". It's been on my Windows 10 computer for about a year and hasn't caused any problems for me at all. Yesterday, I did a Bitdefender scan and got the following message: "The file C:\Windows\System32\ssstars.scr is infected with Gen:Heur.Jatommy.02117.am0@bqkaRbh and was moved to quarantine." Strangely, Bitdefender has never recognized any malware on this file before. I did a Malwarebytes scan and it didn't detect any malware on my computer at all.
I restored the file and uploaded it on VirusTotal and it wasn't flagged by any vendors. I did another Bitdefender scan and now it's not being recognized as malware and it's still on my computer. Is this a sign it was a false positive? I don't know why it was recognized as malware, and after restoring the file to my computer it's not longer being recognized as one.
Also, what category of malware is "gen:heur"?
Would appreciate any insight.
