On 4/25 in the evening I was on some dodgy website and I guess it snagged me because that was when this started.
Every 30 minutes I receive a series of three messages from Norton saying it has blocked an intrusion attempt. "We blocked an attack from System: Infected: Miner.Bitcoinminer Activity X. No further action is required.".
Clicking on details provides the information "system infected: miner.bitcoinminer activity X". X is always either 9, 27, or 7, and in that order. The attacking computer IP is always the same (192.242.218.232, 443). Further, the message says "network traffic from 192.242.218.232 matches a known attack. the attack resulted from \device\harddickvolume3\windows\explorer.exe"
Looking further into history, I see notifications that that address was blocked for 30 minutes. So I suppose it attacks, get blocked, and then when the 30 minutes are up attacks again?
I ran Smart Scan, and then Deep Eraser. No hits. Then I proceeded to search for those messages, and proceeded to download and run assorted software, including stuff suggested here. I've tried (in no particular order): Malwarebytes, RogueKiller, HitmanPro, ESET, Avast, Bitdefender, Microsoft's Malicious Software Removal tool, CCCleaner, ADWCleaner, and Sophos.
Nothing identified anything suspicious, aside from a few cookies (removed).
I should add that occasionally in the last few months (and also after this issue started) I have received a message about suspicious amounts of network traffic, but I do have a cloud backup set up.
So I have run FRST, attaching the files. Also ran FSS, and attaching that file. And...heck I'll attach all the logs I have handy.
Thank you for your assistance.
