TopicLookup Adware (Mac)

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

What is TopicLookup?

TopicLookup is promoted as a legitimate tool (app), however, it is categorized as a potentially unwanted application (PUA), an adware-type app that deploys intrusive advertisements. Additionally, these apps often gather information - usually relating to users' browsing habits.

TopicLookup adware

Adware is a type of software that, once installed, starts serving users with various annoying, unwanted advertisements. For example, coupons, banners, pop-up ads, surveys, and so on. Typically, they occupy website space and conceal underlying content.

If clicked, ads displayed by adware often cause unwanted redirects to dubious, potentially malicious websites. In other cases, they might run scripts designed to download and install other PUAs. Another common problem with having apps of this type installed is information tracking.

They are often designed to collect browsing-related (and other) information: IP addresses, entered search queries, URLs of visited websites, geolocations, and so on. People who create these apps often share the data with other parties, potentially cyber criminals.

These third parties then misuse the details to generate revenue. To keep computers safe from unwanted installations, computer infections, and avoid experiencing problems relating to browsing safety and privacy, we recommend that you uninstall all PUAs (adware-type and others) immediately.

Very often developers present adware and other potentially unwanted software as useful and legitimate, however, when installed, apps of this type rarely operate as they supposed to (as promoted).

Typically, their developers use them to generate revenue and their users receive nothing in return (PUAs do not provide them with any value). Some examples of other adware-type unwanted apps are ChangeToPDF, PDF Mac Master and Snap Media Player.

How did TopicLookup install on my computer?

Typically, unwanted apps are installed when people download and install other software without dismissing them. I.e., when they leave all software setup settings (such as "Custom", "Advanced", and others) unchecked and unchanged. Developers often include unwanted apps into the setups of other, regular software.

This marketing method is called "bundling". They hide information about the inclusion of unwanted apps into setups (settings). In this way, many people allow unwanted apps to be installed together with regular software that they wish to download and install.

Another way to cause unintentional downloads/installations is by clicking (intrusive) advertisements - these should not be trusted.

How to avoid installation of potentially unwanted applications?

Do not use third party software downloaders (or installers), Peer-to-Peer networks (torrent clients, eMule etc.), dubious, unofficial websites and other similar sources to download software. Download using official, trustworthy websites and direct download links. It is important to check "Advanced", "Custom" and other settings of software setup and deselect unwanted apps.

Otherwise, they are downloaded and installed with your chosen software. We also recommend that you avoid clicking intrusive advertisements, especially if they are displayed on untrustworthy pages. When clicked, they often redirect people to untrustworthy websites such as gambling, pornography, adult dating, and so on.

If you encounter these redirects or ads, check for unwanted/unknown extensions, plug-ins, and add-ons installed on the default browser. Also check the list of the installed programs on the operating system and remove all suspicious, unwanted apps/programs immediately.

If your computer is already infected with TopicLookup, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
