Right.
You have – or have had – a Virtumondo infection and the 0Access rootkit (and a bunch of other stuff).
As a minimum, I’d run Vundo Fix and TDDSKiller (see the excellent post by “MrCharlie” here).
However, given the severity of the infection and the nastiness of the payload, I would give serious consideration to backing up anything you want to keep and then wiping the lot and rebuilding. Note that 0Access can compromise personal details; I’d suggest changing passwords for any websites you’ve logged into recently, particularly bank and email accounts. Do this on a clean machine! If you’ve used internet banking or bought anything online I would also, seriously, review your bank balance and recent transactions for malicious activity.
