Exactly. If you have never run a spyware scanner Steve then there is no way of knowing if you have ever had any infections on any of your computers.

Spyware infections are not just annoying because they steal information and send it back to their source. They also cause a lot of other strange behaviour on a system. Certain things suddenly crashing more often, not running at all, the OS doing odd things, some of the hardware not functioning correctly etc... That is the real reason you need to scan for spyware.

As mentioned many many many many times before, only an idiot would think it clever to state they never scan for spyware, let along not running a firewall or having a virus scanner installed and running. But surely such a person cannot exist in this day and age! Can they?
