Defender/malwarebytes/avira pick bitcomet up as malware i dont know to to get it running again

These scans never pick bitcomet as a detection before yesterday night on my laptop.

I had it running and came back seeing the program closed and it says its delete. Didnt know it was by the virus scans at first.

I system restore it.

It ran for an hr until i saw the scanners popup with detections.

Windows defender call it win32/lodi 

Avira and malwarebytes says installcore.gt 

I cant even reinstall it as scans even block the installer dl on bitcomet.com as another detection 

I tried to click allow when windows defender picks it up,  but 2sec later it detects again and automatically delete/quarantine it 

How do it get bitcomet to work again?
