akm Posted February 17, 2013 Share Posted February 17, 2013 Unused File Extension urn:content-classes:wizard/addcontentclass HKCR\urn:content-classes:wizard/addcontentclass Continually appears after registry scan, always right-click and add to 'Add to Exclude list', and again reappears. No big deal, just curious why this particular unused file extension keeps reappearing after add to exclude list ? And, thanks again for your help ! akm (W10,Firefox,Privatefirewall,Avast,Malwarebytes) Link to comment Share on other sites More sharing options...
Moderators Nergal Posted February 17, 2013 Moderators Share Posted February 17, 2013 please read my signature, I it you'll read why this happens add the extension to your exclude list ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.

akm Posted February 25, 2013 Author Share Posted February 25, 2013 Thank you for the reply. Followed your link/s. The unused file extension shows up on the Options/Exclude list, but it also keeps showing up on all registry scans after 'excluded' per image attached. Like said, no big deal, will just ignore the occurence, just thought it was a wierd thing to happen when using Ccleaner. please read my signature, I it you'll read why this happens add the extension to your exclude list Ccleaner-ExcludeListQues-130225.bmp And, thanks again for your help ! akm (W10,Firefox,Privatefirewall,Avast,Malwarebytes) Link to comment Share on other sites More sharing options...
Moderators Andavari Posted February 26, 2013 Moderators Share Posted February 26, 2013 Those will show up, always after applying the monthly Microsoft Updates on my system. I personally let CCleaner nuke them without having any issues (as of yet). Link to comment Share on other sites More sharing options...
akm Posted March 12, 2013 Author Share Posted March 12, 2013 Thanks for the info. Actually, the same UFEs show up the next time I scan, within minutes of the 1st scan when they were 'excluded'. They must regenerate themselves automatically or something ? Guess will just wait and see Those will show up, always after applying the monthly Microsoft Updates on my system.

Moderators Andavari Posted March 12, 2013 Moderators Share Posted March 12, 2013 Since they keep showing up almost immediately after you clean them you're probably using a software that adds them back in - which is a good thing if they're actually needed.
