Many viruses disable taskmgr, regedit, prevent hidden files from being displayed or command from being run with Winkey+R . It would be nice to have a menu with options to re-enable these things or even having a scanner for these issues, that would detect and repair them automatically. I don't think that's a very hard-to-develop feauture since it's all registry keys and you've already had something like that (Security Inspector, which you had in N360 v.2, then you made it as a plug-in for NIS 2009, you promissed to make it compatible with other products, but at the end you dropped support for it).
