I removed avira virus protection (Premium version) now getting C++ errors in my WIN XP OS. I wnt to install the AVIRA free public version but, the C++ errors have made it impossible to bring my pc online. Will I have to reload my pc? Is it possible to 'fix' this without such a drastic step?
Try downloading Revo Uninstaller (+1 to Tilweh), and see if there are traces left from Avira. If there is, remove them. Then download ccleaner, and scan the registry. There may be errors that need repaired.
