How to stop redirects to lp.macsmart-cleanupc[.]club on Mac?

What is lp.macsmart-cleanupc[.]club?

lp.macsmart-cleanupc[.]club is used to trick visitors into believing that their computers are infected with viruses. To remove them, they must supposedly download and install a potentially unwanted application (PUA) called Smart Mac Booster. Do not install or use apps that are promoted through deceptive sites such as lp.macsmart-cleanupc[.]club. The best option is to simply ignore these web pages. If the browser opens them automatically, a PUA is probably installed.

lp.macsmart-cleanupc[.]club scam

At first, lp.macsmart-cleanupc[.]club shows a pop-up window encouraging visitors to take immediate action and begin the repair process. According to the main lp.macsmart-cleanupc[.]club web page, the operating system is infected with three viruses: two classified as malware, and one, phishing/spyware. This web page states that the detected viruses put personal and banking information at risk. To prevent further damage such as loss of photos, apps and other files, visitors must click the "Scan Now" button. When clicked, lp.macsmart-cleanupc[.]club starts a fake scan that 'detects' malware. To remove this, visitors are encouraged to download the Smart Mac Booster application from lp.macsmart-cleanupc[.]club - this downloads an installation file called "maccleaner.pkg", however, there are cases whereby this file is used to distribute other dubious apps. In any case, software that is advertised on dubious, deceptive websites should never be trusted. Furthermore, users are often asked to pay for activation of this software.

Browsers are commonly forced to open deceptive websites (including lp.macsmart-cleanupc[.]club) by PUAs that are installed on them. These apps can also record details and display ads. They gather information such as IP addresses, geolocations, entered search queries, addresses of visited web pages, and other browsing-related data. PUAs might also be designed to gather sensitive information. Developers share the data with other parties who misuse private details to generate revenue in various ways. In some cases, these third parties might include cyber criminals. In addition to information tracking, PUAs feed users with ads such as coupons, banners, surveys, pop-ups, etc. When clicked, these redirect to dubious sites or download/install unwanted apps (the ads run scripts that are capable of these actions).

The internet is full of of deceptive websites similar to lp.macsmart-cleanupc[.]club. Examples include your-mac-security-analysis[.]net, apple.com-clean-mac[.]website, and apple.com-scan-mac[.]xyz. In most cases, they display messages about 'detected viruses' and encourage visitors to download a dubious app that will supposedly remove them. PUAs also cause redirects to dubious web pages, gather information, and/or display unwanted ads. This can lead to problems with privacy, browsing safety, and even identity theft.

How did potentially unwanted applications install on my computer?

It is possible to download PUAs from 'official' websites, however, in most cases, they are downloaded/installed through intrusive advertisements or during download or installation of other (usually free) software. Software developers use a deceptive marketing method called "bundling" in which they include PUAs into the set-ups of other programs. They do this to trick users into downloading or installing unwanted apps with other software. They hide PUAs in "Custom", "Advanced" and other similar settings of the download or installation set-ups and do not disclose this information clearly. When people leave these settings unchanged, they allow PUAs to be downloaded or installed with regular software by default.

How to avoid installation of potentially unwanted applications

Download software using trustworthy and official sources, especially if the software is free. Other channels or tools such as third party software downloaders, installers, unofficial sites, Peer-to-Peer networks (torrent clients, eMule, and so on), and similar sources cannot be trusted. Install software properly and check all "Advanced", "Custom" and other similar options/settings. Opt-out of offers to install unwanted apps before completing any setup. Many intrusive advertisements redirect to untrustworthy sites or download/install unwanted apps. These ads should not be trusted or clicked. To avoid being redirected to dubious web pages or forced to see unwanted ads, remove all unwanted extensions, plug-ins, and add-ons that are installed on the web browser and programs installed on the computer. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
