Let’s put a copy of ravmone.exe in the avast! chest and upload it so it can be added to the detections.
Right click the a-icon in your system tray and click Start avast! antivirus. When the interface opens click the chest icon, then click User Files. In the tool bar click File>Add and navigate to
C:\WINDOWS\RavMonE.exe
Click Open, then close the confirmation window. Now highlight the file and click File>Email to Alwil Software. Add comments if you wish, then click Send Mail. Close the chest and the avast interface.
There are quite a few trojans running on your computer and we can clean many of them now. But I would still like you to run ComboFix as this may root out a few more and will show us some registry entries that cause the infection to jump between you computer and your flash drive.
First download OTMoveIt by OldTimer and save it to your desktop.
Now open HJT and click to Do a System Scan Only. When the scan is complete place a check mark next to these lines being carefull to check all the duplicates:
