How can I restore my desktop?

Best Buy tech support is good at this sort of thing and not that expensive.

Seems like you have a rogue and a bunch of trojans. Use combofix from bleepingcomputer.com, then go download malwarebytes from softpedia.com or cnet.com and use it(rename the installer if it doesn't let you install it such as winlogon.exe), then clean the rest of the virus with superantispyware and Hitman Pro 3.5 from softpedia.com/cnet.com and just in case you do have a rootkit on your system use GMER from majorgeek.com(Use gmer to scan and anything in red delete.)
