An unexpected error has occured during scan


Jus renewed my McAfee Anti Virus Plus program but have been unable to use it. Everytime I want to run a scan, they show the error message as above.

Have downloaded the Virtual Technician but after running a scan it detects no error with the program. Have read that others are having the same problems.. Is there any way to solve this asap?

Re: An unexpected error has occured during scan

Open IE – click tools – Click internet options
Under advanced – click Reset
Close all windows and then try to run a scan

If the former doesn’t help, restart the computer and start tapping F8 key
From the advanced boot options menu select safe mode
Try to run a scan in safe mode and update me on the status

Kindly update me on the status so that we could proceed further

Oh can you also confirm which version of virusscan you have.

If 2009 look at bottom right corner and details or about. If 2010 go to navigation and about.

Re: An unexpected error has occured during scan


   I would like to know some information before we proceed further.

    1. Have you done any hardware changes most recently (EX :System restore ,Reformat,.....etc).
    2. Are you getting any Malware or Trojan alert. 
    3. Check the DAT Version is up to date (Open McAfee -Click -> Navigation->About -underneath virus scan DAT version,Last update date).
    4. Open Run windows (Press Windows button and letter  R).
    5. Type services.msc and click ok.
    6. You will  get services windows.
    7. Select McAfee program and check the Status (It should be started) and start up Type (It should be Automatic).
    8. If you are not able to restart the services than run McAfee removal tool by using above useful links and reinstall the McAfee.
