Also Known As: Ads by TwinValley
Type: Mac Virus
Damage level: Medium

What kind of software is TwinValley?

TwinValley is an application designed to bombard users with intrusive advertisements. It has no useful features and can cause certain problems. Our malware researchers discovered TwinValley while inspecting deceptive pages promoting fake installers. Since TwinValley displays unwanted ads, we classified it as adware.

TwinValley adware

TwinValley adware in detail

TwinValley displays annoying pop-ups, coupons, banners, and other advertisements. Clicking those ads can open phishing pages, technical support scams, websites promoting potentially malicious apps, and other unreliable sites. Also, those ads may cause unwanted downloads/installations. For this reason, ads generated by TwinValley cannot be trusted.

We tested many apps similar to TwinValley and learned that some of them can read sensitive information such as credit card details, passwords, telephone numbers, and more, and browsing history. Having such apps installed on the operating system can lead to monetary loss, loss of access to personal accounts, identity theft, and other issues.

Adware in general

Adware is a type of unwanted software that displays annoying advertisements that promote shady pages and apps. In some cases, adware can be capable of hijacking a web browser and gathering information. Either way, it is highly advisable not to have adware installed on the operating system.

More adware examples are SagaDynasty, MotivePrime, and BasicEngine.

How did TwinValley install on my computer?

It is very popular for adware to get installers via fake Adobe Flash Player and other installers promoted on untrustworthy (deceptive) websites. In other cases, users install adware via ads designed to run certain scripts or software bundles.

Users agree to install adware alongside other software after they finish installation processes without changing "Advanced", "Custom", or similar settings provided in installers. Typically, adware is bundled with freeware (free software).

How to avoid installation of unwanted applications?

Do not finish downloading and installing programs until unwanted apps (optional downloads and installations) are deselected. It can be achieved by changing the settings provided in downloaders and installers.

Also, do not click on advertisements or notifications displayed by untrustworthy websites. Download apps from official pages and stores (avoid using third-party downloaders, P2P networks, and similar sources). If your computer is already infected with TwinValley, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
