Hi, I'm using trend micro 07, which has a few new features, including a list of 'suspicious changes found in my computer'. One of the things detected was registry restrictions. System Change Risk Level: Low Description: You have configured but not activated restrictions on your registry tool. Details: These settings determine if you can run REGEDIT and related Window operating system registry management software. Certain kinds of dangerous software disable REGEDIT so that you cannot undo changes made to the registry. Recommendation: Although suspicious, this new software or change may serve a legitimate purpose. Please investigate further before taking steps to correct this possible problem. My question is, how do I go about investigating this? I was not aware that I configured restrictions on my "registry tool" at all, indeed, I wouldn't know how :s My security setup is: TMIS07 (inc firewall), Spyware terminator, spybot (teatimer active, but no immunization) spywareblaster (installed, but no protections active) SSM paid, but not set to run with windows (giveaway of the day). and avg antispyware and adaware (both free versions on demand only) I did install pctools reg mechanic trial briefly, but uninstalled soon after, when I found that ccleaner does a better job for free. Would any of these have done this, and how do i find out what exactly has been done, and how to undo it? Thanks for any responses. edit- I'm a regular poster now!
