Hello there - my girlfriend's computer came down with a case of AV Care last night - that dastardly deceptive piece of work that is a rogue thing.

I've read most of the sites that I could about removing it, nothings worked so far. I've removed it from the registry, deleted all of AV Care's files.

Although I do believe the main problem is that she actually ran an uninstaller for it. I cannot get mbam.exe to work, and I have renamed it to all possible variations. If I do get it to work, it hangs at 'finishing installation'.

What steps do I take next?


Thanks,
Noah

edit:
PS Hijackthis wont run either. whyyy.

Many malware strains now block many removal products. As HJT is well known, it is a target.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

I cannot use any programs when logged on normally - not even the browsers work. I cant pull up task manager, cant get the start bar..

The only way i can do anything is if I start in safe mode with networking.

You have a nasty rootkit infection

Please download Sophos Anti-rootkit & save it to your desktop.
alternate download link
Note: If using the vendor's download site you will be asked to register with MySophos so an email containing an activation link can be sent to your email address.

Be sure to print out and read the Sophos Anti-Rookit User Manual and Release Notes.
  • Double-click sar_15_sfx.exe to begin the installation, read the license agreement and click Accept.
  • Allow the default location of C:\Program Files\Sophos\Sophos Anti-Rootkit and click Install.
  • A message will appear "Sophos Anti-Rootkit was successfully installed. Click 'yes' to start it now". Click Yes.
  • Make sure the following are checked:
    • Running processes
    • Windows Registry
    • Local Hard Drives
  • Click Start scan.
  • Sophos Anti-Rootkit will scan the selected areas and display any suspicious files in the upper panel.
  • When the scan is complete, a pop-up screen will appear with "Rootkit Scan Results". Click OK to continue.
  • Click on the suspicious file to display more information about it in the lower panel which also includes whether the item is recommended for removal.
    • Files tagged as Removable: No are not marked for removal and cannot be removed.
    • Files tagged as Removable: Yes (clean up recommended) are marked for removal by default.
    • Files tagged as Removable: Yes (but clean up not recommended) are not marked for removal because Sophos did not recognize them. These files will require further investigation.
  • Select only items recommended for removal, then click "Clean up checked items". You will be asked to confirm, click Yes.
  • A pop up window will appear advising the cleanup will finish when you restart your computer. Click Restart Now.
  • After reboot, a dialog box displays the files you selected for removal and the action taken.
  • Click Empty list and then click Continue to re-scan your computer a second time to ensure everything was cleaned.
  • When done, go to Start > Run and type or copy/paste: %temp%\sarscan.log
  • This should open the log from the rootkit scan. Please post this log in your next reply. If you have a problem, you can find sarscan.log in C:\Documents and Settings\\Local Settings\Temp\.
Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
  • Disconnect from the Internet or physically unplug you Internet cable connection.
  • Clean out your temporary files.
  • Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
  • Temporarily disable your anti-virus and real-time anti-spyware protection.
  • After starting the scan, do not use the computer until the scan has completed.
  • When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.
Let's see what can be found in safe mode.

this is quite frustrating - this is the admin profile, but it says it has no access rights.

If you cannot get DDS to work, please try this instead.

Please download RSIT by random/random and save it to your Desktop.
Note: You will need to run this tool while connected to the Internet so it can download HijackThis if it is not located on your system. If you get a warning from your firewall or other security programs regarding Rist attempting to contact the Internet, please allow the connection.
  • Close all applications and windows so that you have nothing open and are at your Desktop.
  • Double-click on RSIT.exe to start the program.
  • If using Windows Vista, be sure to Run As Administrator.
  • Click Continue after reading the disclaimer screen.
  • Leave the drop down box set to default: "List/folders created or modified in the last 1 month (30 days).
  • When the scan is complete, a text file named log.txt will automatically open in Notepad.
  • Save the log file to your desktop and copy/paste the contents into a new topic in the HijackThis Logs and Malware Removal forum, NOT here.
Important: Be sure to mention that you tried to follow the Prep Guide but were unable to get DDS to run.
If RSIT did not work, then reply back here.

Edit : Board anomaly - had to fix formatting errors

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/246331/infected-with-braviax/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses.

To avoid confusion, I am closing this topic. Good luck with your log.

Do not anticipate trouble, or worry about what may never happen. Keep in the sunlight.

Hide not your talents. They for use were made. What's a sundial in the shade?
