If you encounter numerous redirects to the Usd.lucretius-ada.com, other unreliable or questionable web sites on the Google Chrome, Mozilla Firefox, MS Edge and Internet Explorer then this might be a sign that the PUP (potentially unwanted program) from the adware (also known as ‘adware software’) group get installed on your PC.
What does Adware mean? Adware is something that developed in order to display third-party ads to the user without asking his permission. Adware takes control of web-browsers and reroutes them to unwanted web sites such as the Usd.lucretius-ada.com every time you browse the Net. Adware software can end up on your system in various ways. In most cases is when you install free programs and forget to uncheck the box for the third-party software installation.
Unwanted third-party ads
Another reason why you need to delete adware software is its online data-tracking activity. Adware has the ability to gather your browsing history and confidential data, including passwords and credit card numbers. In the future, confidential information about you can be transferred to third parties.
Adware software usually spreads bundled with another program in the same installer. The risk of this is especially high for the various free software downloaded from the Internet. The makers of the software are hoping that users will run the quick installation type, that is simply to press the Next button, without paying attention to the information on the screen and don’t carefully considering every step of the installation procedure. Thus, adware can infiltrate your personal computer without your knowledge. Therefore, it is very important to read all the information that tells the application during installation, including the ‘Terms of Use’ and ‘Software license’. Use only the Manual, Custom or Advanced setup mode. This method will allow you to disable all optional and unwanted programs and components.
