(OP edited to remove exact links, since this had been flagged as “spam: the community feels it is an advertisement, something that is overly promotional in nature instead of being useful or relevant to the topic as expected.”)
Yesterday I installed the WD Discovery software that came with my new Passport WDBYFT0030BBK-WESN drive. I also allowed that program to receive the online update it asked permission to seek.
This morning, immediately after I plugged in that drive, a new tab on my browser (Chrome, on Windows 10) pointed to:
westerndigitalmeasure dot com
. . . which then redirected to three links on haemarthrosis dot stream, those three links blocked by BitDefender.
What is the fix for this?
Update: Here are its processes, per Task Manager: https://imgur.com/54EOkWA . No malware found by ADWCleaner, Hitman Pro, Rkill, or Windows Malicious Software Removal Tool, although NPE generates an error message for the first time, possibly unrelated: “eraser unspecified error 0x8004100b,n44,n66.”
