I'm reading all new comments so don't hesitate to post a question about the file. If I don't have the answer perhaps another user can help you.
hi, so I've got the same file/thing, whatever it is, but mine is registered under TitanArc instead. I've read the guide regarding Malware or legit, and from what I gather, you're saying if the file/thing has proper signature and details, it's most likely not a malware, is that right? So it's most likely legit, right? So mine is probably legit, wouldn't that be right? ._.
Anyway, recently through reimage pc repair online, it says that "...netfilter2.sys -- a variant of Win64/NetFilter. A potentially unsafe GrayWare [AdWare]/Win32.netfilter.a a.k.a Malware.Heuristic!ET(rdm)"
Should I be concerned? (because I don't understand computer jargon)
Anyway, thanks for your article!
