Avira 9 added spyware detection to the free version,but it also came with the really aggravating scan of windows files for signatures,that caused problems with people who had innocent stuff like the ctfmon exe replaced with a dummy. No one complained about these teething pains,and that silly scan was removed,and Avira 9 went on. Avira 10 may not have brought anything revolutionary to the free version,but as an evolutionary step it is nice. The pop up add has always been there. You can set updates at thirty min intervals around the clock if you have the patients to type them in. (No,it is not default,but since when have Wilders users left anything default?) Nothing is worse,and there are real improvements. @aigle: Yes,from my experience with version 9 it averaged five or six updates per 24 hours,other than weekends.
