This is a deceptive program, in other words, a scam based on phishing messages and scareware functions. The primary purpose of such scams include delivering promotional content and tricking users into purchasing or installing useless software.

Potentially unwanted programs come as extras during freeware installations
During downloads and installations of software, programs or updates it is crucial to choose the right option. Experts always inform how Advanced options instead of Default installations can change the outcome of a whole process.
When the user goes the quick route and selects Default or Recommended installations all programs listed on the setup automatically comes to the system without any additional permission required. This activity is unnoticed until the PUP starts showing unwanted and intrusive behavior.
You can avoid these unwanted downloads and installations. The only requirement is to choose a reputable source for your programs and updates or software because it is less likely to get additional applications from official providers. Also, opting for Advanced or Custom installations give you the opportunity of de-selecting programs you don't need or want.
Avoid visiting deceptive sites filled with commercial or suspicious content, clicking on pop-up ads and banners or using p2p services, free-share networks. All of these can lead to unwanted PUP infiltrations and even more severe malware infections.

How to prevent from getting adware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
