About a week ago, an error message started appearing every time I tried to
access Internet explorer, stating that DEP had encountered an error and was
closing the site.

I've tried changing the settings in the 'performance option' window, and
this has had no effect.

Up until a couple of days ago, MSN live messenger was still working, but now
it seems to be blocking this as well.

I'm not that up on computer systems, so if anyone could help me sort this
out (in the simplest terms possible!!) I'd be VERY, VERY grateful!!
