LookupShare – adware that might bring other PUPs to macOS
LookupShare - adware that performs intrusive advertising and redirecting activities
LookupShare is an adware program that takes 12 MB of disk space and appears in the Applications folder of macOS machines. User reports claim that some type of Yahoo redirect virus appeared on Safari after the unexpected installation of the adware app. Continuously, the adware itself might append major changes to web browsers such as Chrome, Firefox, and Safari. You can expect LookupShare to perform modifications on the homepage and new tab search. Besides, the PUP will supposedly relate to harsh redirecting and advertising activities in the nearest future.
|Type||Adware application/potentially unwanted program|
|OS and browsers affected||The suspicious product has been created specifically for macOS computer systems and can appear on web browsers such as Google Chrome, Mozilla Firefox, and Safari|
|Goal||Developers who have produced this suspicious application seek to gather income from the cost-per-click method|
|Activities||The main tasks carried out by this adware are intense advertising during browsing sessions, redirecting to affiliate domains, tracking the user's online sessions, etc. LookupShare virus might even tend to bring other PUPs together with itself|
|Distribution||Adware apps are promoted via software bundling, unsecured networks, and their hyperlinks/adverts|
|Removal||Get rid of the PUP automatically or manually. Try using ReimageIntego to diminish any changes that were hard to remove at the first place|
The aim of LookupShare is to collect cost-per-click income from pop-up ads, banner texts, in-text adverts, and other promoted content. Once the affected user clicks on a particular advertisement, money falls straight to the developers' pockets. Nevertheless, third-parties might try to push bogus products through intense advertising. Most commonly, rogue security software is promoted and users are encouraged to buy a useless tool for a high price sometimes.
Additionally, LookupShare virus might attack you with intrusive surveys and questionnaires and ask you to fill some private or technical details. Usually, users are encouraged to reveal personal information if they want to claim a fake prize or reward, for example, an Android/iPhone mobile phone device. We advise not to do that as by revealing sensitive data, you might put yourself in danger of personal information or even identity exposure.
Continuously, adware such as LookupShare is involved in redirecting activities that are supposed to take the user to affiliate sources and provide attractive-looking deals. However, this process is not that harmless as it might seem from the first view as you might accidentally (or maybe even intentionally) be taken to a malware-laden domain. This is one of the main ways of how users get infected with dangerous viruses such as Trojan horses or ransomware.

Furthermore, LookupShare virus might plant browser helper objects (BHOs) in the infected web browsers. You might spot newly-injected extensions, add-ons, and plug-ins in your browser settings that you did not insert on your own. Also, adware programs can insert tracking objects such as pixels, beacons, and cookies that aim to capture user online activities and browsing history. The captured information usually refers to:
- IP address.
- Search query data.
- Hyperlinks/ads clicked.
- Saved bookmarks.
- Deals/offers searched.
- Commonly visited networks.
After this information falls in the hands of third-parties, they use it to deliver targeted advertising on the users' computer screens. The developers identify what types of products/services are relevant for the user at the moment and generate adverts regarding the person's needs, however, the offers are often fake and created just for income. You might also see some questionable offers and deals from LookupShare adware.
If you start experiencing unwanted activities and changes after the appearance of this adware, you should remove LookupShare from your macOS machine and web browsers such as Chrome, Firefox, and Safari. To terminate the potentially unwanted program entirely, you have to be sure that no suspicious objects are left lurking on your machine or browser apps, otherwise, the ad-supported application might easily return.
You can perform LookupShare removal in two different techniques – manual/automatical. The first one requires the user's interaction with all infected sources and components. The second one requires only employing reliable software and leaving the job for the program. Once the adware is no more on your system and browsers, you can try fixing any corrupted places with a tool such as ReimageIntego in case the PUP has made more difficult changes than expected.
Spreading locations of adware apps and how to avoid them
Specialists from LesVirus.fr claim that PUPs such as adware apps are distributed by using various techniques such as bundling, injecting the download of the suspicious program straight into a hyperlink or advertisement that often appear on unsecured networks such as gambling, gaming, and adult-themed pages.
However, we have good news for users that the secret installation of adware programs is easily avoidable if you just put a little bit of effort into it. Of course, automatical computer protection is necessary, so you should place a reliable antivirus tool on your computer. However, do not forget that manual actions are also required here. You can:
- Change the downloading mode into Custom/Advanced. If you have earlier picked the Quick/Recommended configuration, there should be no surprise that suspicious content has invaded your computer system.
- Avoid visiting unsecured online sources. If some type of website that you are tending to enter is marked as unsafe or you start receiving alerts from your antivirus tool, you should not proceed to it anymore.
- Avoid clicking on suspicious advertisements/hyperlinks. You should not click on every notification that appears on your screen while browsing the web as there might be infectious content delivered. However, if ads start bothering you frequently, consider getting AdBlock or Adblock Plus on your browser for further ad prevention.

Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
