Run HiJackThis again (no logfile required this time) and check the boxes for the following lines:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page =
http://wyborcza.biz/biznes/0,0.html?p=005 (unless you actually wanted that for your homepage)
R3 - URLSearchHook: UrlSearchHook Class - {00000000-6E41-4FD3-8538-502F5495E5FC} - C:\Program Files\Ask.com\GenericAskToolbar.dll
O2 - BHO: Ask Toolbar BHO - {D4027C7F-154A-4066-A1AD-4243D8127440} - C:\Program Files\Ask.com\GenericAskToolbar.dll
O3 - Toolbar: Ask Toolbar - {D4027C7F-154A-4066-A1AD-4243D8127440} - C:\Program Files\Ask.com\GenericAskToolbar.dll
This looks suspicious, not a real Flash Player update:
O4 - HKCU\..\RunOnce: [FlashPlayerUpdate] C:\WINDOWS\system32\Macromed\Flash\NPSWF32_FlashUtil.exe -p
Unless you specifically put this line in to allow 194.204.152.34, then check this line:
O17 - HKLM\System\CCS\Services\Tcpip\..\{408205AD-C232-42EB-94A8-8DBC3A0C24BD}: NameServer = 194.204.152.34
This one looks suspicious, too. Unless you know this file to be safe, check this line:
O23 - Service: B-Service - Unknown owner - C:\Documents and Settings\mirek\Dane aplikacji\Mikogo Extra\B-Service.exe
This is suspicious because this file should be in C:\Program File\Sony\Viao Launcher\ not Program Files\Livebox:
C:\Program Files\Livebox\Launcher\Launcher.exe
Same story with the next file, it's not where it belongs. If you don't use France Telecom, I'd check this one too:
C:\PROGRA~1\COMMON~1\France Telecom\Shared Modules\FTRTSVC\0\FTRTSVC.exe
Once all the boxes are checked, click Fix Checked. Then reboot and report back.
Peace,
Pete Zaria.
