Problems with Error Safe spyware

I'm wondering if one of you computer boffins out there can help me? I've managed to get this Error Safe spyware on my system somehow. There seem to be a lot of free downloads that say they will get rid of it, but I'm not sure who to trust. I don't want to download something that could be hiding even more spyware.
If any of you have a reliable download to get rid of this, it would be greatly appreciated.

AdAware caught it on my computer.

I use spybot and adaware in combination i.e. I run one then the other. Seems to sort out most spyware. Give it a try. You can also set them up so that your computer is immunised against such things. Both are free for download.

Prevention is best.. free is better!!!
Use avg for free antivirus software free.grisoft.com
and ZoneAlarm for a free firewall.

That'll stop most things unles you keep downloading those porn programs!
