Do you think this is a false positive or a real threat?

This morning I have the same problem (Windows 10) and now my LO 5.1 doesn’t work.

Windows defender:
Versione client antimalware: 4.10.14393.0

The same happened to me: yesterday I reinstalled LibreOffice_5.1.5_Win_x86.msi on my Win7 PC and only then could I access my ODF documents. Again, this morning MSDefender showed the same dialog as Gjordis (see above). Today I will update MSD and reinstall LO5.1.5 again … Maybe a False Positive, see also https://www.reddit.com/r/techsupport/comments/58fk1k/ransomwin32cerber/

The same for you, quit using that piece of shit M$E.

My PC sent loads of Phish until MSE quarantined LO 5.1.5 - I got 6 “mail delivery failed” messages this morning.

The email was:

Hello,

There is something important I need
to tell you, that you’d really like
to hear, so please read it here

I’ve installed 5.1.4 and MSE doesn’t object.

I’m putting this here as well as in a comment to the first post to make sure that people see it.

You need to quit using that piece of shit called M$E/WinDefender and use something else, such as Bitdefender (we’ve mostly used Avast but tests have shown it’s worse than the reputation says, where Bf has been nearly perfect, so I’m planning migration). Although Spybot Search & Destroy is great, its module called Tea Timer wastes CPU with its realtime monitoring so don’t activate that.

If you insist on using LO Still versions, take it from www.libreoffice.org !

CONTINUATION: Any malware alert about www.libreoffice.org without separate warning is a false positive.
