Well the file is most likely ok I have that folder and a more recent version of that file but then I have win8. Checked win7 and it has an earlier 1 to the win 8 but later than yours so file seems ok.
The Checkdisk suggestion is maybe the file area on the hard disk is faulty so running a disk chkdisk via the system tools option is a good idea.
Also first navigate to that file and right click scan it does it scan? Do same to whole folder..
See what the above shows and post back after another scan.
To Run SFC open command prompt in Run as Administrator and type sfc /scannow and press ENTER
Post back with screen shot to know the result of the SFC scan
Run a chkdsk as mentioned earlier, if it never proceeds to completion.
Here's a tutorial on how to do it in Windows 8
Chkdsk found no errors. McAfee still gets stuck at 99%. And on the same file.
I can't cancel the scan, and the PC won't restart. I have to crash it.
Did you run the sfc /scannow command as suggested earlier? That should repair this corrupted file, whatever it is.
Did you run the sfc /scannow command
No errors found.
Excluding the winsxs folder from the McAfee scan allows the scan to complete.
The winsxs folder keeps backups of dll's and suchlike for Windows. Maybe there's corruption in there somewhere, who knows? Technical Support are the best people to sort it out I think.
