When you double-click the taskbar icon to open the SecurityCenter there is no "PC Optimization" drawer on the interface?
That should contain Quicklean. Shredder should appear within the Data Protection and Backup drawer.
If it doesn't, right-click the taskbar icon and select updates.
If that doesn't load the tools then you will have to uninstall via Control Panel/Add or Remove Programs (XP), Programs/Uninstall a Program (Vista/Windows 7) then run the MCPR removal tool listed under Useful Links (above), reboot and reinstall from your online account.
The reason why the Virtual Technician sometimes wont detect any products is because you may receive your software from a 3rd party, your ISP for instance and recent changes to the 3rd party provider list have not yet been programmed into Virtual Technician.
