MedusaHTTP virus removal guide
What is MedusaHTTP?
MedusaHTTP is the name of a malicious software that was recently discovered by Brad Duncan. It is a HTTP-based, DDoS botnet malware which is written using the .NET framework. Cyber criminals use MedusaHTTP to perform DDoS (Denial-of-service) attacks against websites. It is known that MedusaHTTP is used to attack casino domains, however, cyber criminals may be using to attack pages of other kind too.
Computers that are 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 with a purpose to make networks (and/or machines) unavailable for other users. They use botnet to attack a particular website/domain, in other words, to create an incoming traffic flood which makes the attacked website unavailable. Simply said, targeted domain becomes temporarily impossible to access. The more bots are in the botnet, the more difficult is to stop the attack. In other words, it is impossible to stop the DDoS attack by blocking a single source (bot). Such attacks can cause businesses a variety of problems: potential or existing customers could not access websites, make purchases, get information about the products or services and so on. Typically, people who have their computers added to botnets are unaware of that. In other words, they unintentionally become a part of DDoS attacks that are illegal. If there is a reason to believe that a computer is infected with MedusaHTTP, it should be removed as soon as possible.

How to avoid installation of malware?
We recommend to 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 and/or tools, functions that are provided by official software developers. Unofficial pages or download tools cannot be trusted. Installed software should not be activated using some 'cracking' tools. It is never legal to use them and these tools often cause computer infections (downloads and installations of malware). One more way to protect a computer is to regularly scan it with a reputable anti-virus or anti-spyware suite and remove detected threats on time. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
