On the affected device it creates a new Windows Service.[2] This service runs automatically whenever user turns on the computer. Then P2PEnhance service connects to a particular website and allows developers to install all necessary files on the computer. As soon as a connection is established, authors of the virus can download and install various configuration files. With the help of these files, developers can create various tasks for the virus. Originally malware has been created to distribute files using torrent trackers. This data might be illegal, dangerous and put the owner of the computer at risk. Indeed, this activity is suspicious, and you might end up with serious problems. For this reason, you need to remove P2PEnhance from the computer as soon as you notice first signs of the infection.

One of the signs of the P2PEnhance virus is computer slow downs because it uses lots of resources to transfer the files. This program might also be capable of downloading unknown entries on the computer as well. Thus, your device can get easily infected with adware, browser hijackers or even ransomware. What is more, you might also notice increased amount of online ads when browsing the web. Besides, this program is also suspected of monitoring user’s data and collecting browsing-related information. In order to avoid such problems, you need to remove P2PEnhance immediately. You can find this application in the “Programs and Features” (or “Add/Remove” programs) in the Control Panel. Of course, you can uninstall it as a regular software, but it might not be enough.

The virus infiltrates the system with the help of free programs

P2PEnhance cannot spread and infiltrate computers itself. However, authors of this program employed another technique to distribute it. They use bundling that allows adding it as an optional component in the software package. If you install freeware or shareware carelessly, you might accidentally install this program as well. The P2PEnhance hijack might occur when you agree to install new software under “Quick,” “Standard” or “Recommended” settings. Such settings rarely openly disclose about additional components and usually installs them by silently. Thus, you need to opt for more reliable setup. In order to avoid potentially unwanted programs, you have to choose “Advanced” or “Custom” settings. However, only choosing them is not enough. You have to monitor the process too. Do not rush to click the “Next” button. Before doing that, make sure that you haven’t left any pre-selected optional applications. It’s important to untick all third-party entries in order to avoid unwanted changes on the computer.
