Hi Jeff,
I just wanted to come back to this and say thanks for all your help in sorting out my issues. In the end I had a few other problems so ended up doing a full reinstall of the op system anyway.
Also, you were right about the trojan collecting bank information. Someone managed to steal £160 from my account, but luckily it was swiftly paid back to me by the bank.
Keep up doing what you do, it's a great thing, and thanks again. There needs to be more people in the world like you, and less thieves!
