Forum:HELP!

MLN will refuse to work and will crash if I click on anything! Also if I type in the name of the building blocks it will turn out like this -!254*^%$^@?: Also instead if going to Google, my computers internet homepage, it will go to the !254*^%$^@?: site! What am I going to do. The antivirus system says there is nothing wrong, but something is not right! I don't want to reboot my computer! We are currently installing some software that will solve the problem, but I love My !254*^%$^@?: Network! Please help!
