What is a Trojan horse?
With a name inspired by the famous Greek myth about the War of Troy, the Trojans are computer threats, which hide their extremely harmful nature under the guise of some seemingly useful and harmless-looking online applications or files. The criminals who create such pieces of software use very sophisticated camouflage, which is intended to trick the users into allowing the Trojan inside their computers without knowing what a dreadful threat they have actually come across. Once inside, the malware tries to perform its criminal tasks in stealth and remain hidden for as long as possible. That’s why it often doesn’t trigger any visible symptoms. In many cases, only a good antivirus software program may be able to detect and catch the harmful virus on time. That’s why we strongly advise all our readers to not neglect the importance of having such software and rather consider it as an investment in their their safety.

What do Trojans do?
Trojans like Sctools.exe, typically, rely on their ability to remain unnoticed for as long as possible in order to perform their harm. For example, they may sit passively on your PC for weeks or even months before they actually receive commands from their creators and get activated. In most of the cases, such malware would be busy exploiting vulnerabilities in your security or collecting information about you, your work, personal life, your online profiles, passwords and accounts. Or it may secretly provide the hackers with remote control over your PC.
After knowing this, it is not surprising that this type of illegal software is so popular among the cyber-criminal circles and why the number of Trojan infections is growing so fast. These threats could be used for practically anything and the fact that they can mask themselves as legitimate files, ads, links, web pages, attachments, torrents and what not, makes it really easy for them to infect any computer. The crooks can program the Trojan to perform a specific criminal task and it all really depends on the specific goal of the hacker. With a powerful virus like Sctools.exe, they can easily make changes to your security settings, your OS processes, software settings, Registry Keys, and pretty much anything that is stored on the infected machine. They may also use the Trojan to insert other viruses into the system without any visible symptoms. There are many reported cases of Ransomware infections which have happened thanks to the previous presence of a Trojan horse on the computer. You surely don’t want to experience the shock of a ransom-demanding message on your screen caused by the presence of a Ransomware on your PC that has been loaded there by a previous Trojan Horse infection. That’s why we highly recommend you run a throughout system scan with the professional malware removal tool from the guide below and remove the hidden malware immediately.
How do I protect myself against Trojans?
This is likely not the first time that you are hearing (reading) this but keeping away from sketchy content, unfamiliar web pages, different intrusive ads, pop-ups, sudden software update requests, free installers and dubious email attachments can greatly reduce the risk of bumping into a Trojan horse or some other nasty virus. That’s why we would advise you to be mindful when browsing the Internet and stick to known and reputed web locations. We already explained above how important it is to have a reliable antivirus software, so don’t lose time and get yourself one. If you are hesitant and don’t really know what kind of software is best for you, feel free to check our recommendation or contact a professional for additional consultation. After all, even the computer experts rely on some good software protection and so should you.
