You may have received a MSA.exe error message in Microsoft Windows. If so, then your computer has been infected with the 'MS Antivirus' virus and you will need to fix it as soon as possible. (MS Antivirus, also known as MSAntivirus, or MS Antivirus 2008, is not from Microsoft. MS Antivirus is a counterfeit antispyware that will severely damage your computer if left unfixed.)
