Once again this week Microsoft has made it clear that NO ONE should be using Windows XP anymore.
The calls have been pouring in from customers who are having their computers lock up or their PC has become extremely slow on boot-up. Upon investigation, it turns out that this is affecting everyone using Microsoft Security Essentials for their antivirus/antimalware solution.
The information I have come across on the internet, indicates that a signature update for MSE was the cause of this. The problem will probably be fixed with the next signature update but in the meantime it has cost companies and individual a lot of time and money to fix the problem.
