  • alter browser’s settings;
  • changing default browser’s homepage, search engine, new tab URL address with a suspicious domain;
  • deliver an excessive amount of ads or redirect[4] to third-party commercial websites;
  • track information about users;
  • cause other browsing-related problems.

You should avoid such suspicious browser add-ons because they may start causing lots of unwanted activities. Some of these activities are annoying pop-up ads that report about discounts, coupons, and other tricky things, redirects [4] to unfamiliar and sometimes really suspicious websites and other activities.

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.
