Welcome to WindowsBBS Assam

Scan again with HijackThis and place a check next to each of the following entries.

F2 - REG:system.ini: Shell=Explorer.exe SCVHOST.exe
O4 - HKUS\S-1-5-18\..\Run: [Yahoo Messengger] C:\WINDOWS\system32\SCVHOST.exe (User 'SYSTEM')

O18 - Protocol: qbwc - {FC598A64-626C-4447-85B8-53150405FD57} - mscoree.dll (file missing)


Close ALL other windows then click Fix Checked. Close HijackThis and restart the computer.

Now, download Deckard's System Scanner (dss.exe) and save it to your desktop.

• Close all applications and windows.
• Double click on dss.exe to run it and follow the prompts.
• When the scan is complete, two text files will open; main.txt, which will be maximized and extra.txt, which will be minimized.

Post the contents of main.txt only for now.
