Threat Metric

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

The following fields listed on the Threat Meter containing a specific value, are explained in detail below:

Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.

Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.

Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.

Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.

% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

Threat Level:	8/10
Infected PCs:	46

Rootkit.MBR.Mayachok.B is a rootkit that subverts your system's normal startup process to compromise its security. In the course of its attacks, Rootkit.MBR.Mayachok.B may hijack your Web browser, modify Internet settings, distribute other threats or synchronize your PC with a botnet. Malware researchers have found frequent cases of Rootkit.MBR.Mayachok.B blocking its uninstallation, even when undertaken by proper PC security products, and the use of strenuous anti-rootkit tactics and tools may be necessary for deleting Rootkit.MBR.Mayachok.B.

The Rootkit that Chokes Your Browser

Rootkit.MBR.Mayachok.B is a rootkit that has been in circulation for at least two years, but recently came to malware researchers' attention in 2014, as a result of new attacks. Only circumstantial evidence about Rootkit.MBR.Mayachok.B's distribution model currently is available, but there are strong indications of Rootkit.MBR.Mayachok.B may be installed by worms that use untargeted e-mail spam to infect new PCs. Like most high-level threats, Rootkit.MBR.Mayachok.B rarely operates alone, and may assist with the installation of other threats along with its own installation.

Like other rootkits, Rootkit.MBR.Mayachok.B may compromise the basic startup settings of your PC, thereby granting threat access to the rest of the system before your operating system has so much as loaded. Although the symptoms of Rootkit.MBR.Mayachok.B infections may be subject to the same variations that its payloads are, malware researchers have noticed the following side effects in recent attacks:

Your Web browser may fail to open some websites, particularly sites associated with PC security companies.
Your browser may experience other performance problems, that may include slow loading times, forcibly loaded advertisements or redirects to unwanted sites.
Your PC may launch audio-based content, such as radio advertisements, automatically.
Task Manager and other memory-managing utilities may display an excessive amount of processes or quantity of resources used by them. Svchost.exe and other, baseline Windows files may be hijacked by threats associated with Rootkit.MBR.Mayachok.B.
Internet connectivity settings associated with your router or modem may experience automatic modifications.

Undigging the Root of a Rootkit

Rootkit.MBR.Mayachok.B may have poor detection rates amongst most brands of anti-malware products, and, like most rootkits, only should be deleted by specialized anti-rootkit security solutions. Typically, an ill-equipped PC security program unable to deal with rootkits may be able to identify Rootkit.MBR.Mayachok.B without being able to remove Rootkit.MBR.Mayachok.B. Since malware experts have found some tangential evidence that Rootkit.MBR.Mayachok.B may be related to worms, you also may want to take particular care to block off local network-sharing routes and removable devices that may be used to distribute more threats.

Although spam e-mail messages could be the main distribution methods for Rootkit.MBR.Mayachok.B and associated PC threats, they also may be exploited to deliver a wide range of other threats to both random and targeted PCs. If you receive unusual e-mail requests that ask you to open attached files or visit an enclosed link, malware experts recommend taking measures to protect yourself from attacks that may launch from these sources. Official websites should be visited directly by typing the Web address into your Web browser's navigation bar, and suspicious files always should be scanned by proper anti-malware equipment.
