I am trying to rehab an old Pentium III PC running Win XP Pro SP2. At one time, it apparently had Trend Micro's OfficeScan Client installed on it. I am trying to get rid of this software so I can run another antimalware solution. I mainly know OS is installed because of its (red) icon in the notification area. I am unable to launch it's user interface. When I look in Add/Remove Programs, it is not listed. I went to the Trend support site and it suggested a utility called Diagnostic Toolkit. I downloaded that and ran it. It gave an Uninstall option, which ran without errors. However, that didn't get rid of the icon. I sent an email to Trend Micro, but have not received a reply. I also ran ccCleaner, but it did not list OfficeScan in its list of installed programs.
Does anyone know how to remove this sticky application? I would like to not reinstall XP, if possible. I am willing to do registry edits, but am a novice at it.
Thanks in advance.
