Adware slips through the installation options

Scammers developed an effective strategy to spread unwanted applications. The essence of this technique lies in pinning down the PUPs to frequently downloadable programs.

After you download one of them, you might often overlook that “bonus” applications come along. Thus, when the installation process is finished, the add-ons which were automatically pre-marked get installed as well.

Alternatively, we offer another way of installing a new program without adware or other unwanted software. Select “Advanced” installation mode rather than “Recommended”. Afterward, uncheck the pre-marked software. If you follow these steps, you will be able to prevent such hijacks in the future.

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.
