P2PEnhance virus infiltrates computers with the help of free software

P2PEnhance is a potentially unwanted program (PUP)[1] that might have been installed on the computer together with free programs that users can download from various online sources. 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. Delete the virus using professional anti-malware program, such as ReimageIntego.

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 might have installed other  files or suspicious third-party applications on the computer and browsers as well. Thus, all these entries have to be removed too, and the best way to do that is to use antivirus or anti-malware software.

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.

The right way to remove P2PEnhance from the device

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
