MedusaHTTP virus removal guide
What is MedusaHTTP?
MedusaHTTP is the name of malicious software that was recently discovered by Brad Duncan. It is HTTP-based, DDoS botnet malware written using the .NET framework. Cyber criminals use MedusaHTTP to perform DDoS (Denial-of-service) attacks against websites. MedusaHTTP is also used to attack casino domains, however, cyber criminals might also employ it to attack certain web pages.
Computers infected with MedusaHTTP malware are called bots, and a group of bots/infected computers is called a botnet. Established botnets can be controlled remotely and allow cyber criminals to perform DDoS attacks against various domains. Typically, cyber criminals perform DDoS attacks to make networks (and/or machines) unavailable to other users. They employ botnets to attack a specific website/domain, thus creating an incoming traffic flood and rendering the attacked website unavailable. The targeted domain then becomes temporarily impossible to access. The more bots in the botnet, the more difficult it is to stop the attack. Therefore, it is impossible to stop the DDoS attack by blocking a single source (bot). These attacks can cause various problems for businesses: potential or existing customers cannot access websites, make purchases, obtain information regarding products and services, and so on. Typically, people who have computers added to botnets are unaware. They unintentionally become part of illegal DDoS attacks. If you suspect that your computer is infected with MedusaHTTP, remove it immediately.

MedusaHTTP is not the only program that can be used to perform DDoS attacks. Other examples are Godlua, GoBotKR, and Megumin. Users of infected machines are often unaware that a malicious program of this type is installed on their systems. If installed, MedusaHTTP runs a process in Task Manager called "Influences Diskview Leukemia".

How to avoid installation of malware?
Be careful with irrelevant emails that contain attachments and web links, especially if they are sent from suspicious/unknown addresses. It is not safe to open files that are included in emails of this kind. Furthermore, software should be downloaded and updated using official websites/tools and functions that are provided by official software developers. Unofficial pages or download tools cannot be trusted. Installed software should not be activated using 'cracking' tools - this is illegal and they often cause computer infections (download and installation of malware). Protect your computer by regularly scanning it with a reputable anti-virus or anti-spyware suite and remove detected threats immediately. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Spyhunter for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Spyhunter for Windows.
