Trojan horse viruses and how to prevent them from getting to your PC

Most Trojan-based threats, like this one and ,are capable of sneaking inside the computer without getting detected. This ability of theirs stems from the frequent use of different forms of disguise to mask the true nature of the malware. Usually, they mask the harmful payload as a harmless and completely legitimate-looking type of web content. It could be delivered in the form of an intriguing email or some other form of spam message, an attachment, an interesting ad or a page-redirect link.

You may get prompted to click, download or install the malware believing that you will get something helpful or free of cost out of it. Sadly, after you perform the action that leads to the contamination, usually no visible symptoms will show up to reveal the infection. Without reliable antivirus software which can detect it, the Trojan is very likely to hide deep inside your system and launch its malicious tasks in complete stealth.

After some time, you may begin to notice some issues with your PC such as sluggishness, unusual system errors and crashes, higher then normal CPU or RAM usage, modifications in your system settings and other unusual activities. However, this is not guaranteed to happen and there may also be no symptoms at all until some major damage of the OS occurs. Your entire data may suddenly get deleted, your system may get totally corrupted, or worse, you may become a victim of blackmailing scheme like the ones in the spam emails or that of a ransomware attack.
