What is yt1s[.]com?
Yt1s[.]com is a highly untrustworthy site offering the service of YouTube content downloading. To elaborate, this webpage can convert YouTube video links to MP3, MP4, and 3GP format files, which users can download.
In addition to infringing copyright laws, yt1s[.]com also uses rogue advertising networks. Visitors to this website can have questionable and malicious pages force-opened or be redirected to them.
Therefore, it is strongly advised against visiting and/or using yt1s[.]com and similar sites.
Websites that use rogue advertising networks promote various sale-based pages (of both legitimate and fraudulent products), unreliable, misleading, deceptive/scam, and malicious sites. The promoted webpages can be force-opened the moment users access the rogue site (e.g., yt1s[.]com).
However, visitors can get redirected to such pages when they interact with the initial website, i.e., click any ads, buttons, links, or other content presented in it. Furthermore, untrustworthy sites typically host intrusive advertisements.
Upon being clicked, these adverts can cause redirects to dubious/dangerous websites, and some can stealthily download/install software (e.g., PUAs - Potentially Unwanted Applications). Additionally, like most rogue sites, yt1s[.]com uses browser notifications.
Should users allow the notifications, they will inadvertently enable the website to deliver intrusive advertisements. Hence, visiting/using yt1s[.]com can lead to system infections, severe privacy issues, financial losses, and even identity theft.
Potentially unwanted applications are often proliferated via intrusive adverts and promoted on misleading/deceptive sites. This software usually appears legitimate and harmless.
PUAs also tend to offer a broad range of "useful" functionalities, which are seldom operational. Instead, unwanted apps can have unmentioned heinous functions. Some PUAs can force-open untrustworthy and hazardous websites.
The promoted web searchers are typically unable to provide search results, so they redirect to Google, Yahoo, Bing, and other genuine search engines. What is more, PUAs usually have data tracking abilities.
Information of interest includes: URLs visited, webpages viewed, search queries typed, IP addresses/ geolocations, personally identifiable details, and other sensitive data. The collected information is then shared with and/or sold to third-parties (potentially, cyber criminals).
Therefore, it is crucial to remove all suspicious applications and browser extensions/plug-ins immediately upon detection - to ensure device and user safety.

How did adware install on my computer?
PUAs may have "official" promotional/download pages. However, they are more commonly downloaded/installed together with other programs.
This false marketing technique of packing regular software with unwanted or malicious additions - is termed "bundling". The supplements can be hidden within the "Custom/Advanced" settings or left unmentioned entirely.
Hence, rushed downloads/installations (e.g., ignored terms, skipped steps, used pre-set options, etc.) increase the risk of allowing bundled content into the system. Once clicked on, intrusive ads can execute scripts to download/install PUAs without user permission.
How to avoid installation of potentially unwanted applications?
It is advised to research software prior to download/installation and/or purchase. Additionally, all downloads must be performed from official and verified sources.
Untrustworthy download channels, e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer harmful and bundled content. When downloading/installing, it is recommended to read terms, explore possible options, use the "Custom/Advanced" settings, and opt-out from supplementary apps, tools, features, and other additions.
Intrusive advertisements appear ordinary and innocuous; however, they redirect to various unreliable and questionable websites (e.g., pornography, adult-dating, gambling, etc.). In case of encounters with adverts and/or redirects of this kind, the system must be checked and all suspect applications and browser extensions/plug-ins detected - immediately removed from it.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
