Interesting... http://www.pivx.com/qwikfix/ "Qwik-Fix™ provides another layer of essential security by closing off the pathways that worms and viruses use to penetrate your PC.. It does not affect any of your virus programs, firewall or other programs. Had users installed Qwik-Fix™ on their PC’s, the recent LovSan/MS Blaster worm and the Sobig virus would have had no impact on them. And, it will close the doors that the next worm will try to enter thru to infect and spread its payload. Qwik-Fix™ is a product of PivX LABS, and results from our work with some of the largest companies in the world. PivX is a premier security research company which has focused its security research efforts on Microsoft’s Windows® and its ubiquitous Internet browser, Internet Explorer. PivX and its worldwide network of security researchers has located, tested and verified hundreds of security vulnerabilities in Internet Explorer alone. As a public service, PivX has also maintained a FREE public online listing of the vulnerabilities that were patched and those that remained Unpatched. Now we have developed Qwik-Fix™, a tool which helps protect your PC from these risky vulnerabilities. Qwik-Fix™ is designed to pro-actively prevent known software vulnerabilities in Windows and Internet Explorer from being exploited by malicious hackers, virus writers and worm writers. Qwik-Fix™ is simple to use, Qwik-Fix™ is easy to download and install. Qwik-Fix™ is dynamic in that it serves as a temporary fix to known vulnerabilities until Microsoft releases a periodic monthly cumulative patch or a new Service Pack. As we find new vulnerabilities our subscribers will be updated immediately, thus staying one step ahead of the bad guys." Does anyone know what exactly this does?
