Since Avast 8.0.1497 update have 2 AvastSvc/exe. files running

My update went well, except I noticed today when checking the firewall, that there are 2 files of the same “exact” name. C:\Program Files\AVAST Software\Avast\Avast Svc.exe both running, however one of them has set it’s owns firewall settings to certain ports which I did not do. I’ve never had 2 files of the exact same name before. The one that set the inbound and outbound port settings is networking with hundreds of connections??
Any ideas. I am just thinking of doing a clean install and see what happens.
Thanks for any other ideas.
