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.
