How did Valenciennes.app install on my computer?

Adware is often bundled with other (usually free or questionable) software and can be installed when users rush through the setup process without checking the installation options. Ignoring sections like "Advanced", "Custom", or "Manual" may lead to unintentionally agreeing to install adware or other included unwanted programs.

Adware can also spread through deceptive ads or pop-up messages on unreliable websites. In other cases, users can download adware via sources such as peer-to-peer (P2P) networks, unofficial app stores, third-party downloaders, free file-hosting services, etc.

How to avoid installation of unwanted applications?

Download software only from official websites or reputable app stores. When installing programs, review each step carefully and deselect any additional software or other unwanted components. Avoid interacting with pop-ups, ads, or links on suspicious websites, and do not permit such sites to deliver notifications.

Regularly update the operating system (and installed programs) and scan a computer for threats using a reliable security tool. If your computer is already infected with Valenciennes.app, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
