I run Windows XP SP3 and have recently asked Kaspersky lab why I constantly need to re-install the Kaspersky Security software. In reply they requested I email the result of a system scan and then told me I need to take Stopzilla from my system. I'd never heard of the software, but on investigation there are Stopzilla entries in my registry. When I try to delete these I find they're 'read only' and can't be deleted. I've searched the Net for info but all advice either seems too complicated or too risky. Is there anything 'safe' I can do to remove Stopzilla? And why is it on my system in the first place?
