Remove Random audio ads in background (Virus Removal Guide)

If you are hearing random audio ads playing in the background, then your computer is infected with a piece of malware known as Rootkit.Boot.Harbinger.a.
[Image: Random Audio Ads virus]
Rootkit.Boot.Harbinger.a is distributed through several means. Malicious websites, or legitimate websites that have been hacked, can infect your machine through exploit kits that use vulnerabilities on your computer to install this bootkit without your permission of knowledge.

Another method used to propagate this type of malware is spam email containing infected attachments or links to malicious websites. Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the Rootkit.Boot.Harbinger.a virus.

The threat may also be downloaded manually by tricking the user into thinking they are installing a useful piece of software, for instance a bogus update for Adobe Flash Player or another piece of software.

When a computer is infected with Rootkit.Boot.Harbinger.a, users will hear audio ads streaming in the background, which causes the system to run extremely slow and slowing down their internet.
This infection can open hundreds of different audio streams.

Rootkit.Boot.Harbinger.a will disguise itself as a svchost.exe to hide itself in the Windows Task Manager. Because it’s expected that there will be multiple copies of svchost.exe running and its workings are quite mysterious to the average computer user, malware authors have long leveraged the confusion around it to hide or at least obfuscate their doings.

    Hello,
    Can you please run a scan with Combofix and post the logs here so that I can get an idea on what’s going on:

    You can download ComboFix from here: http://download.bleepingcomputer.com/sUBs/ComboFix.exe

    VERY IMPORTANT !!! Save as Combo-Fix.exe during the download.ComboFix must be renamed before you download to your Desktop

    Close any open browsers.

    Very Important!!!> Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause “unpredictable results”.

    WARNING: Combofix will disconnect your machine from the Internet as soon as it starts

    Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.

    If there is no internet connection after running Combofix, then restart your computer to restore back your connection.

    1. Double click on ComboFix.exe & follow the prompts.

    2. Accept the disclaimer and allow to update if it asks

    3. When finished, it shall produce a log for you.

    Notes:

    Do not mouse-click Combofix’s window while it is running. That may cause it to stall.

    Do not “re-run” Combofix. If you have a problem, reply back for further instructions.

    If after the reboot you get errors about programs being marked for deletion then reboot, that will cure it.

    Please post the Combofix, so that I can get an idea on what’s going on.
    Next, please run a scan with HitmanPro and Malwarebytes, then let me know how is your computer running.
