Hi,
Download Ewido and install it. Then run, you will receive a warning message saying "Database not found", click "OK" for this.
Next in the main screen, click "Update" and click "Start Update". After the update process, exit from Ewido.
Download CCleaner and install it. Do not run it now.
Reboot in Safe Mode:-
Restart (or switch ON) the PC.
Then, keep tapping the F8 Key.
From the menu that will be displayed, out of which choose Safe Mode and press Enter.
Run CCleaner, click "Options" button and here go to "Advanced" tab and uncheck the option "Only delete files in Windows Temp folder older than 48 hours".
Click OK to exit from the Options.
Finally click "Run Cleaner" and click "OK" to continue cleaning.[/list]
Run Ewido, click on the "Scanner" button in the left menu, then click on the "Start" button.
If ewido finds anything, it will pop up a notification. You can select "Clean" and check the boxes "Perform action with all infections" and "Create encrypted backup" before clicking on OK.
When the scan finishes, click on "Save Report". This will create a text file.
Reboot to Normal Mode.
You are running HijackThis from a "Temp" folder, it is not recommended.
Unzip/extract HijackThis to dedicated folder (like C:\HijackThisFolder\hijackthis.exe).
Then run it and click the button Do a System scan and save log file. HijackThis will perform a scan and saves the log file as hijackthis.log in the same folder where it is installed and it also opens the file automatically.
Copy the entire contents of the file and post it here.
