How do I know if my laptop's been affected by the ukash police virus?

Question

I recently had the ukash virus pop up claiming it was the police, i had to pay a £100 fine etc. I panicked and immediately shut my pc down by holding down power button, and when I started it up again nothing seemed to have changed, i can still access internet,
all webpages,  ive seen no more warning and i've run my usual webroot security scan and kaspersky virus removal tool and both say no threats. I reckon my laptops is probs ok, but i just wanted to make sure that the virus is genuinely gone or its just
lingering unseen?

Assuming it was the ukash virus then from what I understand about it if you were indeed infected then you should have seen the notification come up again when you started the machine up, preventing you from using it. See
http://malwaretips.com/blogs/remove-police-trojan/ for a breakdown of what it does.
On the other hand, if it was something like Cryptolocker (http://www.bleepingcomputer.com/virus-removal/cryptolocker-ransomware-information) instead then from
my experience it doesn't re-appear immediately after booting. If you try accessing any your local files, eg word docs, spreadsheets, images etc, do they open? If not then this might be what you have, which unfortunately is even worse than ukash.
