Hey Alex, not sure if you have checked already, but send you a Xmas present on your school email.

hello there comrade!!

I've scanned everything and changed all passwords. Don't see what else I can do but a full format.

your account is still hacked fyi

Thats the problem, as all it does so far is spread itself. Without spending money on your steam account or hacking further into your personal details, the big security companies don't care if they don't do something serious.

Cheers, done and I've past info on to Westie. Really sorry for that lad.
