I have problems including a pesky blue toolbar which has appeared at the bottom of my browser window. I have followed the instructions re running Adaware and Spybot before downloading HijackThis and scanning my PC. Here is my log (it means nothing whatsoever to me I am afraid!)

Someone will be along to analyze your log soon, I'm still learning so I'll let the experts help you. In the mean time the version of HJT you are using is old, please click HERE and get the newest version 1.98.2. Also you need to put HJT in a permanent folder instead of in your temp internet files so backups can be maintained. HTH

I have deleted the old log in the post and replaced it with a new one from the newer version of HJT as you recommended.

Another problem I have is that AVG is finding a trojan horse Backdoor Afcore BT which it cannot remove as it says it cannot delete:

C:\WINDOWS\System32\shdoclba.dll

I notice that this file appears in the log above?
