Sitool is a virus recognized as a Trojan Horse virus that gets distributed across the Internet with the help disguise. Threats like Sitool are typically disguised as seemingly safe files that users willingly download, thus allowing the malware to gain Admin privileges in the computer.
There are thousands of nasty cyber threats on the Internet but the Trojans are probably the most common and the most widespread of them all. Those harmful computer programs are also very versatile and this makes them a malware of choice for many cyber criminals, online crooks and fraudsters. On this page, we will speak about one particularly sneaky and nasty Trojan-based infection called Sitool and will show you how to safely remove it from your system in case that you have the misfortune to encounter it. It is very important to detect and delete this threat as soon as you notice it because the longer it remains in your PC, the greater the damage it may cause. There are many ways in which the hackers can use a Trojan like Sitool and Wup.exe against you. In most of the cases, this malware is used as a transmitter of other nasty viruses such as Ransomware, Worms or Spyware. Typically, the contamination happens with the help of various legitimate-looking and intriguing types of web content. These could be phishing emails, spam messages, infected attachments, different ads, offers and redirect links, torrents, and even software installers. The idea of the camouflage is to trick the users into believing that they are actually opening a real offer or downloading some useful application, which, in fact, contains the Trojan Horse inside. Fake system update requests and pop-up notifications may also be used as a means of spreading the infection. However, the tricks and the harmful abilities of Sitool don’t stop here. Keep in mind that this is a very dangerous program which has been created to cause harm and to serve the interests of its criminal creators. That’s why, once the infection has found its way inside your PC through one of its numerous transmitters, it secretly starts to launch different harmful processes in the background. Unfortunately, it is almost impossible to detect and remove those harmful processes without the help of reliable security software because the Trojan rarely shows any visible symptoms which can give it away. Before you realize it, Sitool may track down every key that you press and take screenshots of everything that you do. This way it may steal your personal information, gain access to your banking accounts and details, or collect sensitive and embarrassing photos, videos, and other data, related to your work and your personal life. Sitool may also cause serious issues related to your system’s performance and stability. With its help, the hackers may gain unauthorized access to your OS and corrupt, replace or delete different files, system folders, and important components and install other malicious code.
