I'm certain there's malware on my PC that I can't locate. I'm using both Norton Anti Virus and MalwareBytes Professional (alone with MalwareBytes Anti Exploit). MalwareBytes regularly and frequently blocks outbound attempts to connect to one of several websites - most often www.invokefun.com.
Scan with MalwareBytes reports PUP.Optional.Scanguard. JRT removes several folders; Adwcleaner has been reporting no problems. RogueKiller reports PUM.Homepage and deletes the setting specifying which pages to open when I open Chrome. ComboFix gives no message. Log appears to be an inventory of my PC rather than a report of problems. The log is meaningless to me. I've run Farbar Recovery Scan and have the two logs, but these too are meaningless to me.
None of my efforts to identify and resolve the problem have worked and I'm hoping Bleeping Computer's experts can help me. Thanks, in advance, for your help.
