I've recently been getting tons of Medium Risk Unauthorized access targeting NIS. The log always says actor is c:\windows\explorer.exe with actor PID of 2204. This started after getting a strange popup while in IE regarding a virus or malware which I closed without clicking - I then closed IE and immediately did a full system scan which found nothing.
System performance doesn't appear to have been impacted but I'm concerned over the high number of unauthorized access attempts. Should I do a Hijack this scan and report the log here?
Thanks for any advice.
