Hi Henry,
If it is happeinnig for all your exe files, I would suggest you to not only rely upon Mcafee for your computer security.
I recommend uninstalling McAfee first by following the below steps.
- Type Programs and Features on your Windows Start Screen and select it from the list of results.
- Locate the McAfee program you want to uninstall in the list of programs.
- Right click the McAfee program and choose uninstall.
- Select the check boxes for the items you want to remove, then click Remove.
For an anti-virus program, I recommend eSet NOD32 or Kaspersky, if you
are willing to pay for it.
If you want a free anti-virus, I recommend
one (do not run more than one antivirus program) of the following
three:
Avira AntiVir
Avast
Microsoft Security Essentials
I hope this helps.
Regards,
Lokesh
