Very strange longy
Theres loads of stuff that mucks about in your outlook/email programs but ive not heard of anything affecting web-based mail and msn.
Id be emailing their support asap
Dont hold your breath though, their reponses are about as useful as a chocolate teapot, but not as tasty obv.
Yeah done that and had a google search for the problem
It is a trojan horse and have managed to install spybot search and destroy to get rid of it. Bloody annoying nevertheless.
