Are there any signs that can indicate a Trojan infection?

Generally, Trojans are famous for their ability to remain hidden inside the infected system for long. That’s why they don’t usually have any visible symptoms that can give them away. However, if you are observant enough, you may notice some signs that could ring the bell. One of the things is to pay attention to the usual speed and performance of your computer. If it suddenly becomes sluggish and unresponsive, there might be some malware that is eating up its system resources. It is common also to experience some problems with your software such as MS Office, Notepad, your antivirus or some other system programs. If your Task Manager constantly shows high levels of CPU and RAM usage despite that you are not running any process at this moment, this could also be a sign that some activity is happening in the background of your system. In case you notice something unusual, we highly recommend you not to lose time and immediately run a deep system scan with your antivirus software. Bear in mind, though, that it may not be able to detect or completely remove the Trojan, because newer and more sophisticated versions like Vbs.downloader.trojan may disable the security program in order to prevent their removal. In this case, we recommend you use the manual instructions in the removal guide below. There is also a professional Vbs.downloader.trojan removal tool, which can scan your system and automatically detect and eliminate all the related malicious scripts.

How can Vbs.downloader.trojan infect my computer and how to protect myself?

Trojan horses usually spread around the web by various techniques. Some of the distribution methods are still new but sticking to the basic online safety rules can greatly reduce the risk of bumping into malware like Vbs.downloader.trojan. Trying to keep away from illegal websites, suspicious pop-ups, spam emails, links, and attachments is a good start. Also, never download software from non-reputed sources and always be cautious when you install them on your system. It is also very important that you ensure the optimal protection for your OS by updating it with the latest security patches. You should do the same also for your software because, in most of the cases, Trojans effectively exploit system and software vulnerabilities to get inside the machine. Do not forget to invest in a reputed antivirus program and regularly run system scans with it, just as a means of prevention. Such program can greatly help you in detecting malicious attempts or potentially harmful software behavior, which is crucial for catching the infection in time.

Once you remove Vbs.downloader.trojan, it is a good idea to provide reliable protection.
