I am trying Avira Premium to see if it will be my next AV choice. On my Vista32 SP1 and XP Sp3 laptops, everything is humming along perfectly. On my Vista64 SP1 desktop, it's a nightmare. I have tried every trick in the book to get the Webguard to start. I have spent hours on the Avira forums and have seen others with the same situation and no apparent fix. Reps will not say that there is an incompatibility, but no number of clean installs, changed registry entries, manually started processes, or whathaveyou will get the Webguard to work. In the log, it says that the process could not attach itself (?) and every time I boot the log appends a "failure to start" notice. I really like the results with my two laptops and am leaning towards a three-license purchase, but a busted Webguard on the desktop is turning into a dealbreaker for me. Can anyone offer a perspective on what I may have missed or what I should try?
