For the fujitsu, tell us exactly what each disk says on it.
If the MSI trojan is a simple one, this may disable it.
1) Hold F8 during startup, select Safe Mode
2) Hit Control+Shift+Escape and End Process on everything that you can EXCEPT the following: winlogon.exe, csrss.exe, lsass.exe, svchost.exe (multiple)
3) hit WindowsKey+R, type MSCONFIG
4) Startup tab, Disable All
5) Services tab, Hide Microsoft Services, then Disable All... hit OK, YES, reboot.
If that doesn't help you have a more serious virus and the simplest solution is to reinstall windows.
