ok i have mcafee 2006 antivirus . i am getting a msg saying PUP found ( potentially unwanted program ) ok and when i go to remove it it wont let me . it is calling it adware-Virtumundo the file name is pmnno.dll and the file path is C:\\WINDOWS\system32 . it is saying that it cannot be cleaned. ok this happend about a week ago. i couldnt do anything to remove (when i go into safe mode it just freezes after it asks if u want to continue working in sage mode or go to system recovery) so i chose to trust it.after that i started getting a msg when i got on to Internet saying to download Winfixer ok i kept on getting that msg so i downloadit and after that every time i wanted to go to a site or google something i get redirected to a diferent search engine so someone has any advice please respond..
