Its use is recommended to perform a regular maintenance of the computer or prevent such malicious software from being installed on our system.
- Do not open suspicious messages . Especially those emails whose senders are not known or reliable (sometimes you have to check the address from which they write to us), regardless of what you say in your sender. Most infectious emails promise easy money, free services or big surprise prizes. None of that is real.
- Don’t fall for deceptive online advertising . A common way to get infected is by clicking on attractive advertising offers, which usually lead to dead ends and illegally downloading software . Be suspicious of offers that seem too good to be true, and under no circumstances should download or run unknown software and / or downloaded from suspicious pages .
