Fowler just gave you the best info, I am sorry Birdy, I assumed you knew where to Download CCleaner from. That's my mistake there.
@Sbfc, Trend Micro Hijack This is a very advanced program only to be used by professionals, if for some reason you want to use this program I highly reccomend you pay a visit to my friends at
http://geekstogo.com, they will analyze the logs it gives you and instruct you what to do, but Birdy I am sure this is not a Malware issue.
Anyways even if it is, the Malware wouldn't be something to worry too much about as it only does this, there are worse things some can do, but I still don't think it's any form of: Malware, Adware, Trojan, Keylogger, Virus, Rootkit etc.
