Cracking bit of software, scans your PC and lets you know if any of the software has a vuln or needs updating. From what I understand free for home use. Now we all support nuggets all over the land, folk who really only use the PC to fuck it up.
Get this on their boxes, cuts down the footprint for viruses and so on. Keeps all their naff programs current and it's got a dead easy interface. Think of all those reader vulns etc...!
