Okay I have this absolutely ANNOYING problem which includes both Msn messenger and a block checker site.
Everytime I open a conversation window on Msn Messenger, this message automatically comes up in the conversation:
"Did they block you too? Download a free MSN Block Checker http://www.block-checker.com"
As far as I know, I have deleted block checker from my computer and have no idea how to get rid of this awful advertising!!!
Please help. Thanks.
