Looks clean, what's the problem? Some folks have problems with C:\WINDOWS\System32\taskswitch.exe -- but it's not malware.

O4 - HKLM\..\Run: [TkBellExe] "C:\Program Files\Common Files\Real\Update_OB\realsched.exe" -osboot
O4 - Global Startup: Microsoft Office.lnk = C:\Program Files\Microsoft Office\Office10\OSA.EXE
O4 - HKLM\..\Run: [IgfxTray] C:\WINDOWS\System32\igfxtray.exe
None of these are malware, though I'd get rid of them. I replace igfxtray.exe with MultiRes.

Thanks!

So Need Not Do Anything???
Is It Necessary To Delete The Above Mentioned Files???
