I tried to uninstall old and expired Trend Micro Titanium Internet Security suite from the computer that I have restored to factory settings by the usual way. I went to START > CONTROL PANEL > PROGRAMS AND FEATURES, scrolled down and located the software and clicked Uninstall. It started the uninstall process and after few minutes just stopped and gave me message that the installation is corrupted and cannot be removed. Great !
After a while of research I have found a tool that is provided by TrendMicro for FREE. It comes as a EXE file. Once unzipped and run you will get a nice GUI interface, click Uninstall and it will run for a while and completely remove all parts and traces of obsolete Trend Micro software form the computer.
