It appears that this file is affiliated with "savings bull."
I'm definitely no IT/tech guru. Moderately tech-literate, maybe? But I feel like it doesn't take a comp sci whiz kid to avoid PUP's when doing something as routine as d/l a file or adding an extension. Still, I wasn't exactly shocked to see it due to ubiquity of malware/viruses etc. The nameunfamiliarity of the name savings bull immediately set off red flags. A google search later, I launched a modest assault using free/well-known, virus & malware scanners. I also went into my system files to manually check & make sure that it was removed/quarantined.
This was about ~6 months back I continued to keep an eye out for any & all malware related crap. Original removal seemed so quick & easy...too good to be true. Now I find 2 netfilter64.sys files...turning into a never ending game of cat & mouse.
Ran another scan. It said it was successfully removed; we'll see. Running malwarebytes now to see if stragglers are left behind or if it just replicated itself onto another part of my PC. Anyone know a tried and true method of removing netfilter64 or high threat PUP's in general?? Even insights on its behavior would be helpful Like does it make large numbers of copies of itself elsewhere in my HD under different names? If so, then manual removal would clearly be inefficient & useless, despite the peace of mind & satisfaction I usually get from removing a PUP manually hah.
