dat file will not update

On Mcafee Total protection     

Please help, my dat file will not update. I keep getting the annoying message that my computer is at risk. Click update and it turns green for about five seconds and then same message.

Have installed the technician, no help, uninstalled and installed no help.

Many others are having this problem but no solution is posted.


What kind of Company is this?

I have done what you said and I do have 12.1 with a bit of a different interface.

The error message is gone and the software seems to working properly.

Thanks for all your help!

I will post again if something changes.

Hi John

Now that you have uninstalled/reinstalled McAfee, are you still getting updates?  Was the 12.1 version a choice when reinstalling or did the process do that versaion automatically?

Hey Nancy;

I am getting updates and all appears to be working properly. I had reinstalled twice before but it did not get 12.1 but rather the same version which was 11.6. I was using the installation disc befoire this last reinstall.

I believe using the cleaner above resulted in installing 12.1 as it did not offer any options for different versions upon installation.

Hope that helps.
