OTCleanIt by OldTimer was renamed to OTC
several years ago. It is a older utility which was used after a system was cleaned of malware, to automatically clean up an assortment of specialized fix and removal tools used at that time during the disinfection process. The tool has not been updated for some time since the list of fix tools to remove is globally shared between by all of OldTimer's tools. Further, many of the fix tools it was designed to remove are outdated and no longer used. In 2012, OldTimer indicated he had not plans to make any further updates to any of the public versions of his tools.
Although you may still find some downloads links, they are not officially related to or supported by OldTimer and I would advise against using them.TFC - Temp File Cleaner by OldTimer
was later released and is more commonly used today but it does not have a specific target list for specialized tools.
