OT I know but I am curious if there are any similar experiences out there.
I plead guilty to being a bit of a slow learner when it comes to taking on a new operating system.
I stuck with Win98SE till about 2006 and here I am still persevering with XP Pro.
I saw news that support was ending on 8 April so I downloaded what updates I could that day.
Easter Thursday the PC was sluggish to boot – often needed several re-boots – and was prone to crashing/freezing – took me back a decade or more.
All that was worse Easter Friday am and messages started appearing – one was just a warning that XP was not supported – but there was also one of those MS message popups saying to effect – “we are sorry but Antimalware Service Executable has encountered a problem and needs to close” – how I know that feeling.
I had never heard of that file MsMpEng.exe – anyway, I must have rebooted 40 times that morning and got a few minutes online and found it was a Windows8 file and connected with MS Security Essentials which I have used for a couple of years.
So perhaps it was inserted with an update to MSSE ?
Anyway seeing I had no chance of getting any work done I decided to take a risk and see if REGEDIT would solve the thing. Searching for MsMpEng.exe using REGEDIT found about it in about 8 locations – I deleted them all and XP has never run better. I hope nobody else has their beloved XP reduced to rubble like mine was yesterday.
