Harry Hi HMW, Here is a good new : A new malware definition file is available since this morning for XP devices (1.239.990.0). This shows that presently MSE fully performs with XP PCs in spite of all warnings and fuzzy information released since two years on line. Excuse my basic english, this is not my mother tongue..... Did this several times during the day, with the same result.You can reset the anti-virus update engine in your Command Prompt by entering the following commands.You’ll need to press "Enter" after each: Cd\”; “Cd program files\microsoft security essentials Mpcmdrun –removedefinitions –all Exit. When it reboots, open up MSE and click the “Update” button.Under the “Internet Options” tab in the window that pops up you will have the ability to reset your settings under the “Advanced” tab and select your default browser under the “Programs” tab.If updating your frequency and Internet Explorer settings doesn’t fix your problem, you may have an issue with the update engine itself.
