It's quite possible that you inadvertently downloaded MSE to your computer while visiting the Microsoft website; while MSE is not a virus of any sort, it will conflict with other anti-virus programs (such as McAfee).
MSE is easily removed going through your computers Add/Remove Program feature; if it is not the anti-virus program from Microsoft, then follow the steps laid out by Grif(M), for cleaning your computer of virus programs
Somhow, MSE has been downloaded onto my computer which has affected my security protection with; McAfee. I do not have protectio;n at the moment and foir the past two weeks microsoft technicians have been unable to remove it no matter what they try. I have XP PROFESSIONAL installed.
Any suggestions please.
