Hi,

> Check USB storage devices / removable drives


Download MCShield from one of the following links:

MyCity -  Official download link (http://amf.mycity.rs/mcshield/)
Softpedija - Mirror download link (http://www.softpedia.com/get/Antivirus/MCShield.shtml)

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.

Start -> All Programs -> MCShield -> Logs

Attach here -> AllScans.txt

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.


--------------------------------------------------




Download DDS and save it to your Desktop from here:
http://download.bleepingcomputer.com/sUBs/dds.scr

Double click dds to run the tool.

    * When done, DDS will open two (2) logs:
        1. DDS.txt
        2. Attach.txt

Save both reports to your desktop. DDS.txt and Attach.txt attach back to topic.

it is just that some logs are very big, meaning you have to use a number of posts with copy and paste to post it all  ;)

We still have work here, I'll tell you when we're done.  ;)

Has MCShield been running through/via avast sadbox?

Post by: phildaint on March 04, 2013, 09:56:24 PM

I know, but something has prevented MCShield to do his job. We are trying to determine what is it.
Are you sure that MCShield is good/right and fully installed?

> Remove USB mem. device from the computer.


Download fresh MCShield setup and re-run MCShield installation.
http://amf.mycity.rs/mcshield/





> Right click on MCShield in system tray ( blue shield icon ) and click on Control Centre.

- Click on Scanner tab and check the options:

Always unhide items on flash drive


. Attach USB mem. device and allow MCShield to preform the scan.


Start -> All Programs -> MCShield -> Logs

Attach here fresh -> AllScans.txt

Hi,

Ok, that's it. You are malware free.  :)



It is necessary to uninstall ComboFix :
Code: [Select]
ComboFix /Uninstall Note that there is a space between "  ComboFix  " and "  /Uninstall  " .

Wait for the uninstall process is complete.


----------------------------------


I also recommended to you to keep MCShield if you will.
It 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
