Random audio ads

Random audio ads refer to annoying advertisements that are played in the background even when no internet browser is running. You may hear the advertisements when watching a movie or browsing the Internet through any browser. Random audio ads are what you get when a highly malicious bootkit infection gets to your computer. Bootkit infections are not detected by regular computer security programs because their components are located outside the standard file systems.

The infection which launches the so-called Random audio ads afflicts the Master Boot Record (MBR) in order to execute it's malicious code. The code is executed before the operating system loads. Once the fake MBR is loaded, the infection starts working in the background, which means no security programs can detect the vicious intruder. When Random audio ads start to play, the threat returns the original Master Boot Record. This occurs every time you reboot the computer, which means that the infection that is responsible of the annoying Random audio ads control the original Master Boot Record. Note that Master Boot Record is responsible for the proper startup of your Windows operating system and the storage of the information on how the logical partitions are organized.

It is also known that the infection which plays Random audio ads in the background uses the rootkit technique in order to conceal its files. It runs as non-plug and play drivers and hides its files in unallocated drive space, which is empty space on the hard disk.

There are a lot of rootkit and bootkit infections, but the one you have on your is likely to be Rootkit.Boot.Harbinger.a.
