Filereppup reported by Avast Free

I have been playing poker on Ladbrokes poker client for many years but from today my Avast Free antivirus software has blocked the client from running, citing ‘Filereppup’ as being a threat which their fileshield blocked. is this a false positive? How can I know?

The malware type ‘Filereppup’ breakdown is, File, Reputation, PUP (Potentially Unwanted Program).

You could upload it to virustotal.com and see it returned in its multi anti-virus scanner finds. Since it is being detected on your system by the File Shield - you could send it to Avast for Analysis.

You could either allow Avast to send it to the Virus Chest (it can be restored later) and from there, see image example.

You can subsequently Restore and Add Exception if you need it and accept the risk.

Note, my image is an example of a very old detection I retained in the virus chest for these image examples.
