XPFan

in the last three days I have been getting a popup when I go to log into my account. I get a popup with red x in the upper corner and a message similar to "the application for DLL c:\windows\system32\Futunice.dll is not a valid windows image" This popup contues to reoccur whenever I try to open a progaram or go onto the internet. Once on the internet, it seems to go away while I am browsing. I can find nothing on the internet with these search clues. Help Please! Jim
