I’m not sure what you mean by blocking the start page. I have all of spyware blasters protection updated and enabled. I will list the places this trojan has infected so far (the ones that I’ve written down). These all start with C:/windows/ - apisf.exe, atlrr.exe, ntkq.exe, crbi32.exe, iehv.exe, msyj32.exe, apity32.exe, atlfq32.exe, sdkyf.exe, winaw32.exe. I have deleted them all.
