How did adware install on my computer?
Adware and other potentially unwanted applications (PUAs) are often distributed through downloaders and installers for other programs. Users download or install PUAs when they download and install programs without changing "Advanced", "Custom", or other settings that their downloaders and installers have.
Also, PUAs can be distributed through untrustworthy advertisements and fake installers promoted on untrustworthy pages. Users cause unwanted downloads or installations through advertisements by clicking on ads that can run certain scripts.
How to avoid installation of potentially unwanted applications?
Downloads from unofficial pages, third-party downloaders, Peer-to-Peer networks, and other sources should not be opened. It is safe to open files (or install programs) downloaded from official websites and through direct links.
Downloaders and installers with options like "Advanced", "Custom", "Manual" should be checked for unwanted applications. One more way to avoid unwanted downloads (or installations) is not to click on ads that shady, questionable pages display.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
