Thanks GG. I Revo'd it which solved most of the problem. Despite Avira not now showing on Revo nor in 'Programs, I still have an icon in the task bar which links to Avira stuff but, of course, you can't do anything once it gets there. For instance, right clicking on the icon gives me all the former options including 'Start Avira Antivirus 2012' . If I click that then the former screen appears but after that it won't go anywhere else. Any clues on getting rid of this?
