Thanks for the help guys,I ran CWshredder and it came up with a message to say my system is completely clean.
Looked at a few sites,one guy reckoned because it froze on the coolwwwsearch in the spybot dialogue bar at the bottom ,spybot was looking for it,and it was not in his system,was going to uninstall spybot.
Only problem with that,when I did a search for it in threats S.B fixes.CoolWWWSearch came up as unknown.
Not too keen on googling and using an unknown quantity.A few years ago with another computer I found something called Adware,did a free scan but you had to pay for removal.Thinking it was Adaware (I was pretty dumb at the time)I was going to pay for it to fix the problem,but found out in time it planted its own spyware while supposedly fixing things up.Spybot came along and fixed that problem for free.Ironically I think it was a browser hijacker called just Coolsearch,without the WWW.
