Please RUN HijackThis.
. Click the SCAN button to produce a log.
Place a check mark beside each one of the following items:
O4 - HKLM\..\Run: [TkBellExe] "C:\Program Files\Common Files\Real\Update_OB\realsched.exe" -osboot
O4 - HKLM\..\Run: [nwiz] nwiz.exe /install
O4 - HKLM\..\Run: [NvMediaCenter] RUNDLL32.EXE C:\WINDOWS\system32\NvMcTray.dll,NvTaskbarInit
O4 - HKLM\..\Run: [NvCplDaemon] RUNDLL32.EXE C:\WINDOWS\system32\NvCpl.dll,NvStartup
O4 - HKLM\..\Run: [Lexmark X74-X75] "C:\Program Files\Lexmark X74-X75\lxbbbmgr.exe"
As you have probably noticed, I am not deleeting any files, just startup commands. This may have to be tweaked again. We will work on your Kaspersky discovered problems later.
Now with all the items selected, delete them by clicking the FIX checked button. Close the HijackThis window and Reboot Your System
Finally, RUN Hijackthis again and produce a new HJT log. Post it into this thread so we can check how everytjhing looks now.
Regards, It is time for my bed.
