Any ideas why? Did the new version's installer fail to clean up properly? (No problems with previous NIS version) Any ideas how to get rid of them?
Initial removal attempts (CCLEANER & manual) failed no doubt due to Norton self protection (even with all obvious NIS Settings selected to "off"). Can't say I am thrilled by the prospect of looking at these same 4 files every time I run CCleaner for the next 350 days until this licence expires....
PS. IMHO the CCleaner Registry Cleaner is quite conservative/gentle and safe to use if you take advantage of the offered backup option. I have never experienced any problems using it.
I use CCleaner -- there's an update just out -- and I tend to ignore any flags for unused stuff on the grounds that they could be there for use later by the application, perhaps in an update not yet released or needed ....
Especially on something that digs so deep into the system and which I rely on for protection I let sleeping dogs lie ....
