Check it out Rukas, there's a load of them.
I got all of those and I recommend you have more than one because there's so much spyware there isn't even one that scans everything.
So check these ones out:
Ad-Aware Professional 6.0 (my personal favorite)
Scanner (a great program no one knows about)
Spybot (one of the firsts)
Spy Sweeper (a very, very effective program)
Hi Jackthis (probably the best out of all those but I heard is more complex than what it is)
And the best of all, the cream of the crop ladies and gentleman:
Microsoft Anti-Spyware Beta version.
This program is so smart it scans for spyware tactics, spyware known locations and even scans fully your Windows registry. This program is simply the best out there no question asked. Overall I think this one can basically get a load of spyware and you're probably going to be safe with only this one if you decide to choose only one. In other words Rukas try to check them all out and then decide whichever suits you best.
Peace
