Remove TopicLookup (Removal Instructions) - updated May 2019

removal by Jake Doevan - - | Type: Adware

TopicLookup is an adware application that disturbs Mac users with intrusive advertisements and slows down the web browser


TopicLookup is a potentially unwanted program[1] that is usually installed unintentionally when users do not pay close attention to the installation process of shareware or freeware. For that reason, they rarely know where the app came from or what the purpose of it is.

Created for Mac operating systems, TopicLookup might seem like a legitimate application which comes under the name of com.TopicLookup. However, soon after the installation, it performs a set of changes to the way the computer operates and affects Safari, Google Chrome, Internet Explorer, Mozilla Firefox, and all the other installed browsers. 

Soon after that, users might notice an increased amount of advertisement on all websites that they visit, browser redirects to suspicious sites, and even changes to the startup page and new tab URL. Besides this activity that might prevent users from finding relevant information, TopicLookup collects a variety of non-personally identifiable information, which might compromise their privacy.

Besides, com.TopicLookup is recognized[2] by a variety of anti-virus engines under such names as OSX/Dldr.Adload.bojrl, Gen:Variant.Adware.MAC.AdLoad.1, Adware/Cimpli, MacOS:Adload-J [Trj], OSX/Cimpli, and many others.

Name TopicLookup
Alternative com.TopicLookup
Type Adware/PUP

Affected browsers Google Chrome, Safari, Opera, Mozilla Firefox, etc.
Infiltration Software bundling, third-party sites
Main dangers Malware infection, money loss, personal data exposure to unknown parties
Termination Use our instructions below or employ anti-virus software
Recovery Scan your device with Reimage Reimage Cleaner Intego for best results

While technically not malware, users might call the PUP TopicLookup virus due to its stealthy installation and the amount of pop-ups, deals, offers, in-text links and other commercial content it produces. Adware is not considered to be as malicious as such threats like ransomware or trojans, but it might expose users to unsafe sites.

Nevertheless, the growing concerns by security experts and more extensive studies make multiple AV vendors start flagging PUPs.[3] Therefore, a variety of anti-virus software tools can be used for TopicLookup removal.

Apps like TopicLookup are created purely for revenue generation for its developers. Unfortunately, the safety of the end users' experience is often forgotten, which results in an overall negative impact on the computer, as well as browsing struggle. Those infected might see ads marked as following (can vary):

What is more, because TopicLookup is an adware app, it might gather a variety of information about users – mostly related to browsing habits, such as:

  • Search queries
  • Links clicked
  • Bookmarks added
  • Tracking cookies
  • Time spent on each visited site

In addition, other data, like ISP, IP, technical information, might also be collected and even shared with unknown third-parties that are related to com.TopicLookup adware. Be aware that the IP address might be considered personal data, along with search queries, like emails, names and similar data might be entered.

Therefore, if you see ads continually, you should remove TopicLookup PUP from your Mac as soon as possible. It will not provide you any benefit and might even lead you to malware-laden sites, primarily if you actively interact with the intrusive content. After you complete termination, scan your machine with Reimage Reimage Cleaner Intego and reset your browsers for best results.

Pay close attention to the installation of new software

Users are often careless when it comes to online security. While most already know that downloading cracks or pirated software is not a good idea, the potential dangers of unwanted programs like adware are often forgotten. Additionally, it does not help that shareware and freeware authors do everything they can to slip in PUPs into as many users' computers as possible, as each install generates money.

While the practice is deceptive, to say the least, no law forbids it, as the fine print somewhere explains what you are agreeing to it when installing new software. Additionally, pre-ticked boxes often state “By continuing, you agree to Terms and Conditions and Privacy Policy.” And who reads those, right?

We will not ask you to read the lengthy documents, as it is extremely tedious and is not worth the time. However, you should make use of these tips from industry experts:[4]

  • Pick a trusted source for your downloads (beware, however, that even the most known program hosting sites bundle software);
  • Check reviews of the app before installing it;
  • Watch out for deals or offers – decline them;
  • Make sure the important documents are indeed provided;
  • Opt for Advanced installation mode – it will allow you to remove all the optional components before they manage to get in.

Terminate TopicLookup from your computer

To remove TopicLookup, you will have to locate the app in the installed application list and delete it. However, it is not enough to completely get rid of unwanted activities. The PUP creates a variety of entries in your Mac, so simply moving it to trash will not do the trick.
