I tried this several times and just did it again for 32 bit version and same result. Message - Installation failed before Java 7 Update 45 could be installed. To complete installation at another time, please run setup again. Click OK to exit Wizard.
Just completed last of cleaning instructions. Downloaded MS Security Essentials and ran quick scan and DOS Rovnix.V is still there. I can't believe it after all your help my computer is running better but that persistent virus is still there.
