Thank you, AJ. Yahoo Toolbar has now been zapped and the trusty Google one reinstalled. Interestingly, Yahoo must hide itself within CCleaner (I missed the prompt on the download check list) as it didn't show on my Add/Remove Programs option (and it scurrilously seems to have deleted Google from my system upon installing itself). Damn crafty these software development folks.
Firstly, apologies if this post is against the rules, but I can't find an answer on the forum. I downloaded the latest version of CCleaner on Tuesday (for the 1st time) and ran a scan. Great tool and it's freed up a lot of space on my HD. However, it seems to have installed the Yahoo Toolbar and deleted the Google Toolbar. Any advice on how to delete the Yahoo one?
