Trying to update a machine that has been dormant for a while, I got this:

[Pondus]

any change if you reboot?

This detection has been turned off back in January

A virus can sometimes pose as an executable, here AvastEmUpdate.exe, that then could be detected at start-up.

At the moment nothing reports this executable as a (potential) virus at VT: http://www.freefixer.com/library/file/AvastEmUpdate.exe-123120/
Check whether it comes properly signed:
