Hello, I am new to the site and this is my first time post
My laptop has been infected by a search engine redirect virus. I believe it got to the machine as a request to re-register Avast antivirus software (but not really sure)
The virus also blocks all attempts to load any anti malware, anti virus software or even related help sites. On advice of a friend I downloaded malwarebytes and Combofix on another machine, put them on a stick drive and loaded to the infected machine. The virus appears to be blocking me from running these programs as well. I am at my wits end. Any advice/guidence is greatly appreciated.
Running XP.

Please note the message text in blue at the top of this forum.

You should not be using Combofix unless instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Combofix was never meant to be used as a general purpose malware scanner like SuperAntispyware or Malwarebytes' Anti-Malware. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. Please read Combofix's Disclaimer.

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it.
  • Right-click on the mbam-setup.exe file and rename it to mysetup.scr.
  • Change the .exe extension to .scr, .com, .pif, or .bat.
  • Then double-click on mysetup.bat to run.
  • If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe and rename it to myscan.
  • Change the .exe extension in the same way as noted above.
  • Then double-click on myscan.scr to run.
Follow the instructions here for performaning a Quick Scan in normal mode and check all items found for removal. Don't forgot to check for database updates through the program's interface (preferable way) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Thank you for the advice. I was able to re-name MBAM and got it to install. As anticipated it will not run. I am the program file list and there is no mbam.exe.
The largest file is called mbam, should I follow the same steps and rename this file?

The search engine redirct problem is fixed. Thank you for your help.
The instuctions above called for the "Quick Scan", is there need or benefit to going back and doing a "Full Scan" now?

Now rescan again with MBAM but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for database updates through the program's interface (preferable way) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

IMPORTANT NOTE: One or more of the identified infections (UACqmeybwwo.sys) was related to a nasty variant of the TDSSSERV rootkit component. Rootkits, backdoor Trojans, Botnets, and IRCBots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control again. and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Although the rootkit was identified and removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because this malware has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:
