Additionally, it injects malicious script into System's folder %APPDATA% by running the following commands:

\wscript.exe /E:vbscript /B “%APPDATA%\PriceFountain\UpdateProc\bkup.dat”


%LOCALAPPDATA%\{GUID}\synhelper.exe ({GUID} stands for the 32-digit hexadecimal number).

All these changes are initiated to set PriceFountain value. This application is known for displaying intrusive online advertisements within web browsers, track people's web browsing activities, and initiate other intrusive activities without authorization.

Nevertheless, mutuodo trojan along with PriceFountain or any other PUP might turn out to be extremely malicious.

It can open a backdoor to other malicious infections, such as Spyware, Worm or even Ransomware.

Although Trojans, unlike other cyber infections, do not reproduce by infecting other system's files nor do they self-replicate, they seek to open the backdoor on the targeted system and this way give the malicious user access to the system, exposing confidential or personal data to the risk of being leaked.

Thus, an immediate Mutuodo is a must. Otherwise, the Trojan can cause irreversible damage to the system and the data stored on it.

Trojan horse can enter the system in the form of a legitimate application

The name Trojan horse has been given to this infection not without reason. Relating the name with the history of Troy implies that the Trojan as a virus refers to some program or file that does not look suspicious from the initial inspection. However, once it gets into the system, it initiates malicious activities and can be extremely dangerous.

While a reputable anti-virus might help to evade Trojan infections, new Trojans may not be recognized as threats. Outdated virus database may also be the reason why a malicious program bypassed the protection.

Trojan horses are usually distributed as hidden components of mini-games or torrent files. In many cases, they spread as stand-alone installers. Hackers may try to spread them in malicious spam email attachments, fake software updates, and similar means. Thus, make sure to keep your antivirus updated and avoid interference with suspicious content online.

How to prevent from getting trojans

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
