Removing Trojans, Screen Resolution Was Changed

I am running Windows Home Premimum 64 bit. I started having numerous problems a couple of weeks ago, including: Screen resolution was changed, Clear Type and User Account Control were disabled, computer would stop responding temporarily of lock up completely, blue screen at boot up or computer would boot to recovery console, monitor would be on at boot up but would not come out of sleep mode. Finally last night the key board and mouse (both wired) stopped working. I changed the mouse and keyboard to ones that used usb connectors and was able to boot up again, and this keyboard and mouse work, but still having performance issues (hanging, 3D screen saver runs jerky. I tried to run Trend Micro Housecall but could not get to run. I tried to update the Nvidia drivers several times and my computer would shut down before the installtion was completed everytime. I would get a blue screen with the notice that the computer had been shut down to protect it from damage. Norton 360 found nothing. I have since uninstalled Norton. Ran AVG, nothing.

Finally Kaspersky online deep scan found these:

C:ProgramFiles(X86)Online ServiceseBayWizLink.exe Trojan.Win32Agent.cwkw
C:ProgramFiles(X86)Online ServicesESPwizlink.exe Trojan.Win32Agent.cwkw
C:ProgramFiles(X86)Online ServicesquickenfcWizLink.exe
Trojan.Win32Agent.cwkw

But did not offer a way to remove them.
