I have a license for webroot, actually. It cost me $4.99, on newegg.
I it was blocking firefox for some reason, the support couldn't figure it out. they just kept saying it works for them.
I have run into same issue. Webroot was blocking HMP.A and some other legitimate, safe files.
I just add to PC Security > Allow\Block Files > Allow. That fixes problem.
There are some quirks with Webroot that the documentation does not explain:
Get alert, Block - Allow Once - Allow Always for *.exe; if you select Allow Always then Webroot will add to Allow\Block Files - Monitor; you have to change to Allow.
Get webpage block - allow page; Webroot will allow permanently.
Get alert, Block - Allow Once - Allow Always for script (*.vbs, *.js, etc); if you select Allow Once then Webroot will Allow Always.
Webroot will sometimes auto-block files - even safe - without alert; only way to know it is blocked is to look in Allow\Block Files.
Webroot will sometimes auto-block file from accessing personal data - even safe files only way to know it is blocked is to look in Identity Shield.
I am not sure, but I think the anti-clipboard and anti-screen capture only applies to unknown files trying to access clipboard\make screen capture.
Webroot calls the default scan a "Deep Scan," but all it does is scan the most commonly infected areas; marketing. That's why the Webroot scan is so fast; it only scans a limited number of directories. At least Emsisoft calls theirs a malware scan.
There's a lot more.
Webrooters toot-toot their horns that Webroot support is so good, but in my experience it is typical frustrating experience. More and more users are complaining. There seems to have been some recent internal changes - I think they outsourced - but I could be wrong.
Ask questions about Webroot mechanics and you can never get a straight answer.
I have a love\hate relationship with Webroot. I report bugs\problems and Webroot and its fanboys will not even admit that there
might be a problem. As far as their attitude shows, they all seem to think Webroot is perfect and nothing needs to be improved.
