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

%APPDATA%\PriceFountain\UpdateProc\UpdateTask.exe

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

Nevertheless, mutuodo trojan along with PriceFountain or any other PUP might turn out to be extremely malicious. Recently, several people reported^[3] that the infiltration of this Trojan ended up with a total system's hijack since the Trojan managed to compromise Microsoft account's password.

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 Outdated virus database may also be the reason why a malicious program bypassed the protection.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.
