How did adware install on my computer?

People often cause unwanted downloads and installations unintentionally by clicking intrusive, deceptive advertisements or downloading and installing software without checking the settings. Many people download unwanted apps together with other software when developers use a deceptive marketing method called "bundling".

To trick people, they bundle/include unwanted apps with software set-ups and do not disclose this information properly. They hide these rogue apps in "Custom", "Advanced" and other similar sections. When people download or install software without checking or changing setup settings, they often inadvertently download/install unwanted apps.

How to avoid installation of potentially unwanted applications?

Use official sources (websites) to download software. This does not include third party downloaders, unofficial pages, Peer-to-Peer networks (torrent clients, eMule etc.), and other untrustworthy sources. Never skip setup steps when downloading or installing software.

Check "Custom", "Advanced" and other similar settings/options, and dismiss offers to install or download anything you do not require. Only then finish the setup. Intrusive ads, specially if displayed on untrustworthy websites, redirect to deceptive, dubious websites such as gambling, adult dating, pornography, and so on. These advertisements should not be trusted/clicked.

If you experience these ads or unwanted redirects, check your browser for unwanted, unknown apps such as extensions, add-ons, and plug-ins and remove them.

These programs are installed on the operating system and should also be uninstalled. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
