Startupchecklibrary.dll

Startupchecklibrary.dll can be a trojan horse in disguise of a legitimate windows file.

A new Trojan has been recently reported to our “How to remove” team, and this time the malware goes under the name of Startupchecklibrary.dll. If you are reading this article because your personal computer has been secretly compromised by this particular Trojan, it is best to quickly figure out how to detect and eliminate it. Trojans, especially the new and sophisticated versions like Startupchecklibrary.dll, can be very unpredictable and can damage your entire system before you know it. Fortunately, we are here to help you prevent that and deal with the malware ASAP. As a start, we will first point you towards the information in the next paragraphs, just to help you get an idea of how serious the infection with Startupchecklibrary.dll can be. Next, we recommend you to take a look at the removal guide at the end of the article, and at the attached professional removal tool. Ideally, with their help, you should be able to remove the Trojan from your system.

There was a problem starting Startupchecklibrary.dll

Startupchecklibrary.dll is a new malware variant of the Trojan Horse type that can compromise your computer without your knowledge and launch a number of harmful processes on it. Typically, Trojans are used for espionage and BitCoin mining, but some of them can also distribute Ransomware.

Like most malware programs and viruses, the Trojans typically use a blend of different infection methods, and a variety of transmitters, which can deliver the harmful code into your system. Their goal is to sneak in without getting detected, and in order to achieve that that, they typically use some common types of web content (such as ads, pop-ups, email attachments, social media links and messages, torrents, free downloads, etc.) as disguise. One careless click on a random pop-up message may easily inject an infection like Startupchecklibrary.dll into your computer without showing any visible symptoms. Therefore, we always advise our readers to be careful while browsing the web and to not click on shady sites and links, too-good-to-be-true offers, suspicious deals, or clickbaits.

Unfortunately, this is usually not enough to fully protect you from an accidental encounter with a representative of this category. Therefore, investing in reliable antivirus software is always a good idea. In fact, in most cases, it is very difficult to detect and remove the Trojan without the help of a professional security tool, because these threats are very good at hiding themselves in unusual system locations. An infection like Startupchecklibrary.dll, for instance, may mimic some regular system processes or files. What is more, an advanced Trojan of this kind may silently operate in the background of the OS and launch different harmful activities without your knowledge.  

The infection methods associated with Trojans.

Trojans are stealthy – they use camouflage and can operate in secret for an indefinite period of time. But what makes them even more feared is the fact that they can be used for a long list of criminal actions. The harmful capabilities of threats like Startupchecklibrary.dll are limitless. They can be programmed to perform one harmful activity after the other, and there is no way of knowing what can happen to your computer. The criminals who are in control of the malware can use it to gain full remote access to your machine. They may also use it to hack into your webcam, or mic, and secretly spy on you. Trojans are also a malware type oftentimes used to spread Ransomware cryptoviruses, to perform identity thefts, and to conduct banking frauds. Through a method known as keylogging, the Trojans can steal your passwords, login credentials, credit or debit card numbers, and other sensitive information. They can transmit data from your computer to remote servers without your knowledge, but what is even worse is they can modify, replace, remove or destroy all the information stored on the infected machine.
