Landost.com POP-UP Redirect

What is landost.com?

When visited, the landost.com rogue website causes unwanted redirects and displays deceptive, dubious content. The internet is full of websites of this type. Some examples of other similar sites are looksslike.com, fastpushnotification.com, and seriencev.com.

User do not generally arrive at landost.com intentionally - this is due to potentially unwanted apps (PUAs) installed on their systems. PUAs are often installed inadvertently and go on to open dubious sites such as landost.com, deliver intrusive ads, and collect browsing-related (and other) data.

When a PUA is installed, it continually forces browsers to open landost.com in a new window or tab. When opened, this website displays content or opens additional websites (about 2-3) that might be untrustworthy or potentially malicious. The way in which landost.com operates depends on the location of the visitor.

Furthermore, as mentioned in our introduction, unwanted apps usually deliver intrusive ads. They achieve this by employing tools that enable placement of third party graphical content on any site. Therefore, coupons, banners, surveys, pop-ups, and so on, conceal underlying contents of visited websites.

This can be annoying, since, when clicked, these ads open other untrustworthy websites or execute scripts that download and install other unwanted apps. Furthermore, PUAs are categorized as information tracking apps. They record information such as IP addresses, search queries, URLs of visited websites, geo-locations, and so on.

In many cases, they also gather personal data. The recorded information is continuously shared with third parties (cyber criminals) who misuse it to generate revenue. We recommend that you eliminate all installed PUAs immediately and avoid them in future.

There are many potentially unwanted apps on the internet. Their developers offer various "useful" features and tools, and they present these apps as legitimate.

In fact, when installed, PUAs record sensitive information, deliver advertisements, and cause redirects to untrustworthy websites. This is to generate revenue for their developers rather than provide the functionality promised or any other value.

How did adware install on my computer?

Some PUAs can be downloaded from their (supposedly official) websites, however, they usually infiltrate operating systems/browsers when users click intrusive ads or when the "bundling" method is used. Bundling is a deceptive marketing method that allows third party applications (PUAs) to be installed together with regular software.

Generally, developer hide bundled (additionally-included) apps in "Custom", "Advanced" options/setting of software download or installation set-ups. Furthermore, many users skip or rush software download/installation steps and do not check available settings (they leave them unchanged) - this allows PUAs to be installed.

How to avoid installation of potentially unwanted applications?

Avoid downloading software from unofficial sources, using torrent client, eMule (and other Peer-to-Peer networks), third party software downloaders, and so on. The best way to download software is using official and trustworthy websites (channels).

Download and install software with care, and do not skip download/installation steps without checking all available "Custom", "Advanced", and other similar parts. Opt-out of offers to install or download unwanted apps and only then complete the set-up. Furthermore, avoid clicking ads, especially if they are displayed on dubious/suspicious websites.

These can open untrustworthy websites such as gambling, pornography, adult dating, etc. If you experience unwanted, random ads and redirects, check installed plug-ins, add-ons, and extensions (browser apps) on your browser and uninstall dubious entries immediately.

Also check the list of installed programs on the operating system. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
