Hello,
Internet Security 2010 is a tough one especially if it comes with Trojans.
1. Reboot your PC in Safe Mode with Networking.
2. Download Spyware Doctor

If you can complete the above steps then you are lucky. That means there's only IS2010 without any additional malware. However, if you can't install or download Spyware Doctor then removal will be more complicated.
1. Download HijackThis from
http://go.trendmicro.com/free-tools/hijackthis/HijackThis.exeNOTE: rename HijackThis.exe to explorer.exe before saving it.
2. Launch HijackThis and click “Do a system scan only†button. Look for such entries in scan results:
F2 – REG:system.ini: Shell=Explorer.exe logon.exe
F2 – REG:system.ini: UserInit=C:\WINDOWS\system32\winlogon86.exe
O4 – HKLM\..\Run: [winupdate86.exe] C:\WINDOWS\system32\winupdate86.exe
Select those entries and click the “Fix checked†button. Then close HijackThis.
