Recommendation to under General and Scanner tab you click on Defaults button to choose recommended options.

When all scanning is done, you need to attach a logreport that has made MCShield.

Explanation: USB storage devices are all the USB devices that get their own partition letter at connecting to the PC,
e.g. flash drives (thumb/pen drives, USB sticks), external HDDs, MP3/MP4 players, digital cameras,
memory cards (SD cards, Sony Memory Stick, MultiMedia Cards etc.), some mobile phones, some GPS navigation devices etc.

Ok, it’s time to remove used tools and they will do some post cleaning…

It is necessary to uninstall ComboFix :

[*] Click Start (or
http://amf.mycity.rs/pg/images/VistaStartButton.png
) then Run.

On Windows7 or Vista you may use Start Search field if Run is not available.

[*] In the line of text type in (Copy) the following:

ComboFix /Uninstall

Note that there is a space between " ComboFix " and " /Uninstall " .

[*] then click OK (or press Enter ).

Wait for the uninstall process is complete.

Re-run OTL and click on CleanUp! button.

You will be asked to reboot the machine to finish the cleanup process, choose Yes.
After the reboot all the tools we used should be gone.
Note: Some more recently created tools may not yet be removed by OTL. Feel free to manually delete any tools it leaves behind.

I recommended to you to keep Malwarebytes and MCShield if you will.

MCShield will prevent infection by computer via USB flash drive, mobile phone or any other memory card.
And not only will prevent infection, but will immediately clean Memory card or external HDD

Be safe :wink:
