What kind of application is QuestDevice?

Upon our evaluation of QuestDevice, it was evident that the app inundates users with intrusive advertisements, categorizing it as adware.

In order to mitigate potential adverse outcomes, it is recommended to uninstall QuestDevice from computers.

QuestDevice adware in detail

Once QuestDevice is installed, users may encounter deceptive ads, fake software updates, misleading promotions, or other content that attempts to trick them into clicking. Ads from QuestDevice can lead users to a variety of potentially problematic pages.

Users may be redirected to deceptive websites that mimic legitimate ones, aiming to trick them into providing personal information, downloading malware, or falling for scams. Also, adware-generated ads might direct users to phishing pages designed to steal login credentials, financial information, or other sensitive data.

Some ads may lead users to fake technical support pages, where scammers attempt to convince them to pay for unnecessary services or provide remote access to their devices. Moreover, ads from QuestDevice might encourage users to download seemingly legitimate software or updates, which can be malicious or unwanted programs (e.g., browser hijackers).

Additionally, users may be directed to fraudulent schemes, fake lotteries, or other online scams designed to trick them into making payments or divulging personal information. Sometimes, interacting with ads from apps like QuestDevice can result in unwanted downloads and installations.

It is important to mention that QuestDevice may be designed to track the websites a user visits, record the user's search queries, collect information about a user's preferences, or even attempt to capture usernames and passwords entered by the user. Sometimes, apps of this type may capture sensitive financial information, such as credit card details.

How did QuestDevice install on my computer?

Users often install adware together with other (mainly free) programs when installers for those programs include additional apps. In these scenarios, unwanted installations occur when users do not change the provided settings (e.g., "Advanced" or "Custom") or untick checkboxes.

Additionally, clicking on misleading advertisements, pop-ups, and notifications from shady pages, and downloading from unreliable sources like P2P networks, third-party app stores, deceptive websites, etc., can lead to accidental installations.

How to avoid installation of unwanted applications?

In order to avoid such occurrences, users are advised to download software only from reputable sources, carefully read through the installation prompts, and remain cautious when interacting with online content (ads, links, pop-ups, etc), especially from unfamiliar or suspicious websites.

Regularly updating and using reliable antivirus software can also provide protection against adware. If your computer is already infected with QuestDevice, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
