JS/ProxyChanger.CW Trojan Removal

This page aims to help you remove JS/ProxyChanger.CW Trojan. These JS/ProxyChanger.CW removal instructions work for every version of Windows.

Trojan horses are very famous in the world of cyber threats. They are believed to represent the most common threat you can catch on the web. Their functions and means of distribution could be very different. That’s why we have created this article – to let you know what to expect from an infection with a certain Trojan – JS/ProxyChanger.CW. In order to assist you with the process of removing this malware, we have also included a special Removal Guide.

What to remember in case you are facing a Trojan:

Trojans are a category consisting of many viruses with various functions. What gathers them in a family is the way they invade and then harm you and/or your computer. Normally, all their activities go unnoticed until the very end. Usually, the victim users usually realize an infection has occurred after the virus has already damaged their systems. That’s why you should check your PC for malware as often as possible. New virus versions appear on a daily basis and your particular anti-virus program may not have included them all in their databases. Also, remember that a functional anti-malware tool is an up-to-date one. Applying updates on a regular basis is required. So, now that we have already explained the typical way that these viruses tend to act in, let’s get to the bottom of why they called Trojans. They invade your computer in a subtle way, and then they simply lurk there silently, while waiting for the best time to implement whatever malicious deed they have been programmed to. The way they function has reminded programmers of the way the treacherous wooden horse from the Trojan War and the way it used stealth to enter Troy and attack from within. We all know that the Trojans believed it was harmless at first, which resulted in the Greeks conquering the besieged city.

What may potentially go wrong because of the contamination with JS/ProxyChanger.CW?

Possibly the most frightening aspect of being infected by any Trojan is the uncertainty. You can never tell what the true purpose of JS/ProxyChanger.CW is before this malware version has achieved its, normally awful, goals. Here we have enlisted the usual usages of JS/ProxyChanger.CW and Trojans in general. Just remember that thus list doesn’t include all the possibilities, just the most typical ones, according to the experts in this field.

  • Hackers entertaining themselves. Yes, it happens. Some hackers might be willing to create and spread malware as a way of simply having fun and exploring their own skills and creativity. This is neither normal, nor is it harmless. Still, such a possibility doesn’t lead to any dangerous consequences, and is not considered the most serious kind.
  • The need for destruction and creating chaos. It’s simple – some cyber criminals may just desire to crash some systems and delete some data for no particular reason. No information or money is required from your side. The hackers might simply format your disks; corrupt your data; or complete damage your entire device. It is not possible to comment on such a crazy behavior.
  • Stealing sensitive information (sometimes entire identities). This exact possibility is among the most frightening ones. Such malware, including JS/ProxyChanger.CW, may be exploited, and often IS, for getting access to some sensitive private details. Some cyber criminals could need access to your social media accounts or banking ones in order to commit a crime.  Stealing your money or involving you in another potential disaster is more than possible. Such a scenario might involve the victim users ending up unable to prove that they are themselves. All their private information, which is available online, may be modified or destroyed.
  • The act of spying on you personally or professionally. This scenario is again a really nasty one. Some cyber criminals could be willing to physically target you. Consequently, your PC  may end up infected by a virus like JS/ProxyChanger.CW, and you may end up being spied on 24/7. Usually, Trojans are exploited for spreading other malware types, typically, Ransomware-like viruses.
