open cloud av malware

Recommended Posts

I am helping someone who has a laptop that was infected by open cloud av on October 3, 2011. I read the warning that it may be impossible to remove the trojan backdoor installed by the malware. I have been impressed by the sophistication of the code and I am concerned that it can't be effectively removed? [i know very little about trojans, but I noticed that the roaming folder was being modified - making me think that the code was actively communicating with an unknown server] Given what you know about this variant, what are the odds that the backdoor can't be locked? Thanks, PS

Hello, and welcome to Malwarebytes, PSSnyder:

Sorry to hear that your firend's computer may be infected.

Alas, we cannot work on malware detection/removal in this part of the General MBAM forum.

Please read the following to get started on the cleaning process:

  • Excellent, self-help troubleshooting info for getting MBAM to run on an infected machine can be found here.
  • And there are specific, self-help malware removal instructions here, with specific instructions for Open Cloud here.

If you would like expert assistance with cleaning your system, there are 3 support options from which to choose:

  • Option 1 -- Free, Expert advice in the Malware Removal Forum
  • Option 2 -- Free support for paying customers using MBAM PRO -- Contact MBAM Support via email
  • Option 3 -- Premium, Fee-Based Support


As we don't deal with malware removal in this General MBAM Forum, you need to start a topic in the Malware Removal forum so that a qualified helper can help you fix any malware related problems/infections you may have.

  • First, please print out, read and CAREFULLY FOLLOW the directions here, skipping any steps you are unable to complete.
  • If the infection has so crippled the computer that you cannot follow most/all of the requested steps, then please just proceed as advised below:
  • Then please post a NEW topic in the Malware Removal forum.
  • Please do not reply to open posts started by other members in the malware removal section, even if the problem appears to be similar.
  • When posting your new thread, under "options", make sure to select Track this topic and choose Immediate Email Notification, so that you're alerted when someone has replied to your post.
  • One of the expert helpers there will give you free, one-on-one assistance when one becomes available.

IMPORTANT NOTE: Please do NOT make any further changes to your computer such as (Install/Uninstall programs; use special fix tools; delete files; edit the registry; OR use temp file cleaners, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.

IMPORTANT NOTE: Please DO NOT post back to your topic or "bump" it within the first 48 hours.

Replying to your own posts changes the post count from zero. Helpers are looking for topics with zero replies. If you reply to your own post, helpers may think that you're already being helped and thus may overlook your post. This will only delay your obtaining assistance.

  • o If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
    o You may send a Private Message to a Moderator asking for assistance.


Alternatively, as a paying customer using MBAM PRO, you can contact the help desk at support@malwarebytes.org or here.


If you would like to use the Malwarebytes Premium Services (Comprehensive solutions to all your computer support needs -- from installation and set-up to troubleshooting and tune-ups), please go to the Malwarebytes Premium Services support site.

Please be patient -- someone will assist you as soon as it is possible.

Thanks very much!


PS: Please use the zMn2t.jpg button instead of other ones when you reply here and at the other forums, so that it will be easier to read. :)

Thanks - I am trying the specific Open Cloud AV removal method of Sept 11. This variant seems especially difficult as it starts a loop of processes and threads that makes it very, very difficult to get Malwarebytes to run. Open Cloud keeps your program in the background by using modal warning windows to cover it. I was successful in getting focus to the Malwarebytes window only by repeated use of "switch to" from task manager. It is running now but very slowly, probably due to constant creation of files by Open Cloud with warning balloons in the task bar. If this does not work I will upload HiJackThis logs to the other forum. BTW - when I updated MalWareBytes the McAffee AV module that is "turned off" reported unauthorized outgoing email, I guess Open Cloud is sending "invitations" to people in the address book. Thanks again, PS
