It must be having trouble unpacking a compressed/zipped file, but that's only my guess. I hope you haven't been running registry cleaners as they can often cause this.
Make sure that Windows 7 is totally up to date, also make sure that IE is up to date (IE11), even if you never use it.
Make sure Flash and Java are up to date also and that your System Clock is accurate. Just trying to cover all bases here ;-)
Use Task Manager to end the scan, it will take a while but will stop eventually. The stop button in the software is disabled if the software is in the middle of scanning a large folder.
Your versions look old to me so I wonder if your software is provided by a 3rd party?
Download the Virtual Technician and run it, see if it finds problems and fixes them for you. http://mvt.mcafee.com/
It is progressing through the scan at 81%, just very slowly. The file names being scanned didn't look like zip folders/files - just dll's etc...
I haven't a clue what a registry cleaner is, let alone run any!
Software is updated directly via the internet - I have full admin rights, it;s not a corporate image.
How do I use task manager to stop the scan? I've tried so stop the relevant 'process' that but it told me it was locked.
I'll download the virtual technician and see if that can find anything...
The easiest way is to right-click the bottom taskbar and select "Start Task Manager"
You just then click End Task on the Applications tab.
Once stopped then do the MVT thing.
it doesn't show as an application, just in Processes. I had to shut laptop down to stop it (which took 22 minutes).....
Running the MVT now....
Both build and engine dates are over 1 mth old so update not working and 13.6 version way behind current.. Who did you get Mcafee from and what operating system.. What is the affid number in the about details box under the 13.6 version build number.
Please try the below steps
1. Disconnect the external devices connected to the computer
2. Open McAfee and Run Quick Clean from Navigation on Top Right
3. Select Quick Clean and Click Clean
4. Run Scheduled Scan
5. If it stuck at any %, share the screen shot of the same.
