Securitycheck.pdf False positive or virus?

[Nickbandit1]

Hello Guys. I had noticed earlier today, that i might have had a virus, either way, i decided to just freshly install windows 10 as it has been a long time since i've last done so. However, after getting AV, Steam and drivers installed Avast popped up saying i had gotten a virus from a dokument named: DOCUMENT_SECURITYCHECK_8CUUPIDU7PHJD1.PDF

It says that the file is infected with Malware-gen[Trj] and that it was located inside of a windows folder in the AppData section. more specific inside of some folder by the name windowscommuncationsapps_(wekyb3d8bbwe

Anybody knows if this is a virus or a false positive? And if it is a virus, how is it possible for me to get that with nothing downloaded or installed other than steam and Graphics drivers

Thanks in advance.

By 'freshly install' , do you mean repair install, with 'keep my programs/files', or, delete partitions/full reinstall? (The former could easily allow miscreant apps/files to survive, obviously)

um - do you happen to know the origin of the document? By its name it seems to being generated by some antivirus software.
