Hi,
seems like you didn’t fix all HJT entries Raman told you to:

start the PC in safeMode (F8-Boot) then fix the mentioned items, ESPECIALLY:
O4 - HKLM..\Run: [DSS] C:\WINDOWS\tcposmod.exe
check with taskmanager, if you can find & kill the related Process

Also fix/delete all your O16-DPF entries as it’s a bit too cluttered there

then rerun hijackthis and check the log again (Still in safeMode)

VGREP: you have to try all links, then you would have got e.g. here:

also run Onlinescanners from
