I am very sorry for the false positives!

Can you please send me your Avira logs (located in c:\ProgramData\Avira\Antivirus\LOGFILES) and 3-5 of the quarantined files (c:\ProgramData\Avira\Antivirus\INFECTED\ - .qua files) to

heuristik2@antivir.de

?

Also I need the full path where all those "suspicious file" detections are/were located.

Hi Stefan,

I uninstalled Avira, so am not able to provide the requested files, but perhaps one of the other people here can do it for you.

Hi stefan - isent you the log file to the mail. Hi Guy - by uninstalling avira did you recover the deleted files or you had to install them again?

No, I couldn't, so I just reinstalled mathematica. But then the question is what happened with the registry when avira quarantined the files? Did it remove mathematica from registry? Did it really thorougly clean it? It feels like something was left behind as my mathematica system settings don't seem to stick.

OK, I got things back (I think/hope) eventually.

I'm on Windows 8.1 and had 30000+ files in quarantine.

I disabled UAC completely.

In batches of about 600-800 a time I asked the files to be rescan-ed (F2). More at a time did not seem possible.

Once they were all done I restored (F3) all files to original location, again in batches. In this case it looks like I could have done them all at once. But I did in batches.

Then I deleted them all from the quarantine directory, in my case C:\ProgramData\Avira\Antivirus\INFECTED

And re-enabled UAC

Mathematica 11 works for me.

I feel this is a morally wrong solution, avira not coming back till they fix this.
