The US Department of Defense has is taking bids for protecting military computers against spyware. Of course, if I had a surefire anti-spyware package available for distribution, and was offering it for free, I doubt the DOD would take it. Even if ongoing maintenance was non-existent – fully automated – and the whole package was platform independent and 100% bulletproof, they still wouldn’t take it. You know why.
So I wouldn’t follow in their footsteps, whatever or whomever they decide to go with.
