Uninstalling Anti-virus Software

[TomyP]

 
I have Trend Micro Officescan Client 7.3 software installed on my notebook PC with Windows XP Professional. My PC was once part of a network domain; I inherited it with Officescan Client. Now I need to uninstall Officescan in order to install a new single unit anti-virus program. Officescan however asks for a password as part of the uninstall process. Unfortunately I do not have the password or any way to obtain it from the network administrator who may have set it up in the past. Is there a way to get around this problem and uninstall this software without causing serious problems to my computer or operating system
