Ok Viliam mate there is a problem with Direct X driver that has come through with an update

Code:

*******************************************************************************

*                                                                             *
*******************************************************************************
UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault).  The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
        use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
        use .trap on that value
Else
        .trap on the appropriate frame will show where the trap was taken
        (on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT
Arg2: 0000000080050031

What I suggest id uninstall the driver and reinstall it using the refs from here

Ha ha!! yep it is William and Viliam appears on the dump files as Viliam-PC - everyone who posts back with anything like that has the name of their machine attached and most people like myself name the computer after their own name (usually) on install or setting the thing up

OK I don't quite understand what you mean by stuff I didn't post you but one thing you can try even though you did get rid of malware a while ago is to run this - doesn't take long and is a bootable scan so it will not involve Windows.
Kaspersky Rescue Disk 10 read though the link and of course the choice is yours but I have used this a quite a few times I the past on my machines and fixes too.
