VirusTotal is a web site that you can upload suspect files to and have multiple different virus scanners (over 40+). This can confirm a detection is good or a possible false positive.

Version 2015.10.3.2219 is a beta version, you won’t get this unless you elect to download it and install over the top of your existing. So Beta versions aren’t installed on regular program updates, unless you have previously installed the beta version.

Beta testing is not to be entered into lightly, especially on a non-testbed system. Whilst I don’t know your experience level other than from your posts in the forums, my advice would be to stick on the regular program update channel.
