Just a word of warning.
One of our ladies at work downloaded by mistake, ( You know how confusing some sites can be when wanting to download software ! )
a program Mcugl 5.0.2900.2180 which poses to be a anti virus program, installs itself into the application data folder and then drives you crazy with all the viri it finds and urging you to buy the program because the PC is totally virus infested . ( $ 79 ) !
This is not a proper program as it does nor appear in the program list and no way of a conventional uninstall. It even claims that it is a MS product !
The only way to get rid of this junk is to boot in safe mode and simply delete the application in the application data folder.
I even googled but can find no reference to this "program"
