There’s a different form of malware floating around, in the form of a rootkit, known as Rootkit.Boot.Harbinger.a. Users are reporting audio ads streaming in the background, which causes the system to run extremely slow and slowing down their internet. It can open hundreds of different audio streams. It appears to disguise itself as a svchost.exe that uses a lot of your CPU in task manager.
The easiest way to get rid of this malware is to run Kaspersky’s TDSSKiller.
Save it to your computer and run it. Tell it to start scan and let it do its thing. It should only take a couple of minutes and will probably require a reboot. If it finds a threat, let it reboot to clean it.
