Just sitting using my computer only to suddenly here the PC get a little loud! So I immediately check my task manager to find a file named mrt.exe running at 30%+ capacity of my processing. Following this, I found some other files like svchost.exe, and another that I ended the process for.....also running after mrt.exe was finished running.
I then did a file search on my computer for mrt.exe and did find the file is windows system 32 file. However, I then find a windows prefetch file mrt.exe-1b4a8d49.pf file. The latter file shows as a being modified today right at the time when the computer started this. Any idea if this is a virus going on, or is this a normal modification occuring?
