180search Assistant Alert box

There has been a grey box popping up on my screen after my computer has loaded. It has been happening for a month or so. I do not know if it is a virus or not. I have launched Network Associates virus scanner, Vshield and Ad-aware 6.0 and still the box does not popping up. It only pops up once, never pops up again after you close the box.
It says:
WARNING
The system has detected that a third-party application has removed 180search Assistant, possibly without your consent. This may cause some programs not to run as expected. Please choose an option below.

Options:
- Re-install 180search Assistant so that your programs will run as expected. Requires internet connectivity.

- Leave 180search Assistant un-installed, and clean up any 180search Assistant files or settings that remain.

- Remind me later.

Any Help with this would be greatly appreciated.

Thanks,

I googled 180Search Assistant and found this site which explains what it is:
http://www.180searchassistant.com/faq.html Then there is this site:
http://www.180searchassistant.com/uninstall.html which tells you how to uninstall it. It seems that 180search Assistant is installed as a part of many free software applications, screensavers, games and Internet accelerators - so you may have installed it unknowingly. Hope this helps.

 

Try running spybot search and destroy. also use spywareblaster. Also try to check if it is installed in your system.

Good Luck!
