And as I said it's not only for malware, CD-emulation software is notorious for messing up stuff, this can be usually solved by deactiving its non-pnp driver.

I've had to remove at least two dodgy non-pnp drivers from my system in the past two months. One of them was daemon tools related (on my system for a perfectly legitimate reason, I hasten to add). The other was a piece of anti-virus software I'd long since uninstalled  that thought I might appreciate it leaving drivers behind on my system for years...
