Hello. OneStep is something you "agreed" to dl, prob on the back of some free tool..
Start hijackthis, select Scan Only, place checkmarks against all the entries listed below that still exist, and then press Fix Checked.
O4 - Startup: Sonic CinePlayer Quick Launch.lnk.disabled
O4 - Global Startup: Ulead Photo Express 4.0 SE Calendar Checker .lnk.disabled
O23 - Service: OneStep Search Service - Unknown owner - C:\Program Files\OneStepSearch\onestep.exe" "C:\Program Files\OneStepSearch\onestep.dll" Service (file missing)
Good. Go Start, run, paste in this and press enter:
sc delete "OneStep Search Service"
Do a hijackthis scan only and check that O23 entry is missing; if still there then:
==Go Start, run, type services.msc -and press Enter. Maximise the window and select Extended tab at foot, scroll to the specific service, rclick it, select properties. Write down the exact Service Name. Press Stop if it is highlighted [you may have to set the service to Disable first]. Close Services, now type this line into the run text box and press Enter:
sc delete "exact Service Name" - don't be silly now....
Now delete this: C:\Program Files\OneStepSearch\onestep.exe
..and the folder.
