The hackers may also extract information about you by installing special keylogging scripts, which can keep a track of everything you type using your keyboard. Your passwords, online accounts, banking details and any other sensitive personal or professional information could easily be copied and handed over to the hackers, which may use it to abuse and blackmail you as they please.

How to stay safe?

Keeping your computer well-protected and secured against this (or any other type) of malware is of utmost importance. That’s why in every article we share the best prevention and protection practices and tips that can help you improve the security and safety of your system. In the case of Trojan horse infections, if you want to stay protected, you need to know how these threats get distributed and what to avoid in order not to get infected. Sadly, there are numerous types of web content, which could easily be converted into transmitters of viruses like Rat Virus and the hackers who use this sort of malware get more and more creative with each passing day regarding their distribution methods. A general safety rule is to avoid visiting sites which have a bad reputation or contain illegal or pirated content. You should also keep an eye on your email inbox and delete spam messages, especially ones that have suspicious attachments or ones that have been send by unfamiliar senders. Such spam messages are often used as bait for the distribution of threats like Rat Virus and similar nasty infections. Needless to say, another great security precaution is investing in a reputed antivirus software as in many cases you may not be able to manually recognize/detect a potential infection. A professional security tool, however, may be able to catch and remove the threat on time, before it has managed to cause you any harm.
