Seems though you have various malaware/trojan infections.
Virtumonde comes in various guises and is sometimes incorrectly identified
by malaware/virus apps.
I'm unsure as to whether your saying you cannot boot up at all, as you say
you have installed various spyware apps, in an attempt to remove the
malaware.
Is your Keybd a usb one? if so you have access to a ps2 keybd?
Try this page, in particular the 'Trend Sys Clean pkge' - this worked for me
when my kids pc got infected and Adaware/Spybot/Spyware Blaster/WinDefender
could'nt help

Assuming you can boot, or once you can boot, ensure you turn off sys restore
untill you are sure your sys is clean.
Once sys is OK ensure you have a decent Firewall and AV software
ZoneAlarm and AVG have free versions, often reccommended.
