Sophos home, 

Since the 28th of october I've been getting a message stating a scan will start due to ransomware detected a few days ago.   I perform a scan and nothing is found but everyday i get this message.

The file mentioned in the history is,  C:\ProgramData\Microsoft\Windows\UUS\Packages\1212.2309.20012.0\amd64\wuaucltcore.exe

I've submitted the file and check with sophos online tools that say its likely safe.  

Before this I had a message sating that a windows update was blocked do to ransomware.  I've since then, check and repaired windows update and have updated successfully. 

However this message pops up every day and it freaking me out lol. 

I've read a few documents on here but with no resolution to my problem. 

Is this a false negative?  what can i do to stop the message if my machine is safe.

Best regards 

Malcolm
