Please let us know what error message you see in security center while it stops working ?
Please provide us with a screen shot of the same when its disabled or such ,.
Did you previously have any other security software installed on the PC ?
How is your computer connected to internet ? DSL/wireless ? Do you have any issues with the network connectivity ???
On every occasion there has been no error message and no warning - I have discovered it 'by acident'. This last time I could see the M shield icon in the task bar and I chose to click on it just to remind me when my account would expire. It would not open and would not respond in any way either with right click or left click.
The previous two occasions were more obvious as the M shield logo went missing from the task bar and when I clicked on the desktop icon nothing happened. On the previous two occasions I was able to delete the application using Windows programme removal and then I ran the removal tool. This last time - Windows would not allow me to remove the application but the removal tool removed it.
You can see the reports I obtained using MVT attached to my post.
McAfee came preinstalled by Dell and it has been updated ever since. The computer is connected to the internet DSL router by ethernet cable and the wireless is disabled.
I have not had issues with internet connectivity.
Thanks and regards
