Hi Marcos, Regard https://www.wilderssecurity.com/showpost.php?p=1827870&postcount=8 When you use 360Amigo and click find error for first time, It will not only scan the junk files, registry errors, fragmented files, but also scan the Internet Defence(more than 8k+ ActiveX for immunization, 2k+ black list for Cookies Tracking, 1k+ website black list). Click Fix Errors will fix all the things. So the "problems" here means all the things should be fixed. I hope it will be clear for you to unserstand the logic in the program. BR
