Hello - I am here asking this question for my girlfriend. Over the past couple of days, her computer has had problems with Google redirecting her on the internet (which has since subsided). She has also had issues with running Malwarebytes - she tried to reinstall it and it gave her the error that she does not have access to the appropriate files, etc. She runs McAfee on Windows XP and it has also been disabled several times by something running on her computer. McAfee also has problems scanning her computer for viruses. In addition to all of this, it is causing her computer, mainly Mozilla, to lock up and force her to restart. I really need some help to get her computer up and running correctly again. Any information/help would be appreciated.
