Stealth and sneakiness
Trojans Horse infections are known for their stealthy behavior and overall lack of symptoms both when the malware initially infiltrates the computer and during the time it stays inside the attacked system. In most instances, a virus program like ServHelper would be getting distributed under the guise of some piece of content that would initially seem legitimate or at the very least harmless. Such a piece of content could be an attachment (file or link) added to some spam message to your e-mail, Skype or social network accounts, a attractive-looking online offer, a fake update request or maybe a misleading advert. Pirated program downloads are also very commonly used malware distribution tools and oftentimes they might contain Trojan infections. There are numerous other possible ways a Trojan Horse virus could be getting distributed – the ones mentioned above were only some of the more popular ones. The important thing to remember is that, in order to keep your system safe, you really need to be very cautious with the content you tend to interact with while online and with the locations that you normally visit. This is the only way to decrease the chances of running into some malicious malware source.
As we already mentioned, Trojans are difficult to detect while inside the system and though certain PC behavior irregularities like sudden errors, crashes and unusual system resources consumption might indicate that there’s an infection, oftentimes the only somewhat reliable way of spotting such a threat would be through the use of a dedicated security program like a strong antivirus or anti-malware tool.
A multipurpose threat
As we pointed out at the start of this article, Trojans are versatile threats and could oftentimes be used for a variety of insidious task. A virus like ServHelper might be employed to corrupt the data on your system (or the system itself), to spy on your activities, to steal sensitive information, to load other malware programs like Ransomware, Rootkits, Worms, etc. inside your PC and so on. There could really be many ways in which such a threat could harm your machine, data and your virtual privacy which is why you need to make sure to take away the malicious malware piece before it has managed to fully carry out its task.
