Remove PUM.Bad.Proxy Quickly and Easily

By | January 8, 2015

Hi, I wonder how to remove a Trojan from my computer. Eset NOD32 detects it (its name is PUM.Bad.Proxy) but just fails to remove it completely. Now some of my files have been hidden and I can’t unhide them. I think thoroughly removing PUM.Bad.Proxy may help fix this problem. I’ve tried several ways to remove this threat but have no luck. Hope someone can help me with this problem.


What Is PUM.Bad.Proxy?

PUM.Bad.Proxy is a Trojan horse used by cybercriminals for online fraud and theft. It often masquerades itself as a harmless or even beneficial file or application in order to mislead you into installing it on your computer. When running in your computer, it will start carrying out a range of actions according to the commands set by its creators. This Trojan horse does not self-replicate in your computer like what a worm does; it will drop its malicious codes to your hard drives, which enables it to accomplish the successor tasks. Generally, this Trojan horse consists of two parts, the client part and the server part. The client part serves to perform various tasks on your computers, and the server part is responsible for data transmission, namely, connecting to the cyber hackers’ computers and transmitting the information or data collected by the client part.


Should You Remove PUM.Bad.Proxy?

The answer is yes. As we have mentioned above, this Trojan horse often disguises itself as a legitimate file or application, but in fact does something malicious in the infected computers. As soon as installed, it will inject its malicious code into the legitimate files executed by the operating system and then execute operations that you won’t want on your computer, typically causing data loss or information theft, and possible system harm. This Trojan horse is capable of stealing important information (credit card numbers, passwords, etc.). Then it sends the sensitive information using the network on the infected computers to its creators, who then would use the information for malicious purposes.

PUM.Bad.Proxy will also make destructive damage to your computer system. It will randomly delete files, including the system files and personal files. Therefore, you may encounter system crash or blue screen of death suddenly, and find that some important files are missing without reasons. What’s worse, this Trojan horse could bring more threats to the your infected computer, which may cause more and more problems. A considerable slowdown in computer performance is one of the problems caused by the infections. You may also be annoyed by many unexpected pop-ups while surfing on the Internet. It will not be a pleasant thing to use a computer with so many problems. And it is dangerous to ignore this Trojan horse, since it can generate some serious problems like data loss, identify theft and system damage.


Why Is It Hard to Remove PUM.Bad.Proxy?

You may find it hard to detect and remove a Trojan horse using your antivirus program. Why? First of all, it should be known that an antivirus program or anti-malware program can help protect your computer from malware just because that it is able to recognize that they’re actually malware. However, in these days more and more malware are created by cyber hackers for various purposes and not every type of malware can be easily recognized by an anti-malware program, especially one that hasn’t been updated for a long time. In addition, some cyber hackers know much about how anti-malware programs work and they can write a Trojan horse which has the ability to bypass most security tools.

PUM.Bad.Proxy is such a Trojan horse that can evade detection and removal by a general anti-malware program. When downloaded onto a computer, it will quickly load itself into the Windows registry, which allows it to be executed every time the computer starts up. Also, it will disguise itself as a part of the system file, attempting to evade detection by the antivirus program. Moreover, this Trojan horse will try to kill process of the antivirus program so as to disable it. All these can explain why it becomes a so difficult task to remove the Trojan horse from an infected computer.
