What is flv2mp3[.]by?

Flv2mp3[.]by is a website that operates as an online video downloader and converter, it allows users to download videos from YouTube and convert them to .avi, .mp4 and .mp3 format files. However, this page uses questionable advertising networks, it means that it contains ads that redirect people who click them to shady websites. It is not recommended to use services that are provided by such pages, besides, it is not legal to download videos from YouTube.

flv2mp3[.]by pop-up redirects

Typically, ads on websites like flv2mp3[.]by, if clicked, cause redirects to various questionable websites. For example, those ads redirect people to deceptive websites that are designed to inform visitors that their computers are infected with viruses. In most cases those pages encourage visitors to remove infected files and/or malicious programs with some untrustworthy application. Also, ads on flv2mp3[.]by might lead to sites that are designed to advertise other potentially unwanted apps (PUAs) like browser hijackers, adware, etc. If installed, browser hijackers change certain browser's settings so that users would be forced to use/visit some fake search engine or other dubious address. Also, most apps of this type are designed to gather details relate to user's browsing habits. Sometimes they might be used to record sensitive information as well. Either way, very often gathered data is being misused to generate revenue which means users are being put at risk of having their identities stolen, they could experience problems related to browsing safety, privacy, etc. Adware, if installed, serves intrusive ads that usually are designed to redirect people to untrustworthy websites. Some examples of ads that usually are displayed by adware are banners, pop-up ads, coupons, surveys, etc. In some cases clicking those ads results in causing unwanted downloads or even installations. It happens when certain ads run scripts that are designed to cause it. Furthermore, flv2mp3[.]by asks for a permission to show notifications. We advise against allowing such pages to show their notifications. They serve users with various irrelevant, annoying notifications, they start to advertise questionable software, websites, and so on. Example of flv2mp3[.]by notification is provided below.

Flv2mp3[.]by is not the only website that offers YouTube video downloading and converting service, a couple of other examples are y2meta[.]com, mp3-youtube[.]download and 2conv[.]com. It is not recommended to use such websites not only because it is not legal to download videos from YouTube. Typically, those pages use questionable advertising networks and, if used, redirect users to various shady pages and/or contain ads that cause the same problem. Besides, people who use websites like flv2mp3[.]by may be tricked into downloads or even installations of unwanted applications.

How did adware install on my computer?

Potentially unwanted apps usually get downloaded and/or installed without user's knowledge. It most cases people download and/or install them through intrusive advertisements that they click or when developers use a deceptive marketing method called "bundling". They use it to trick people into downloading and/or installing unwanted apps together with software that they downloaded intentionally. As a rule, information about additionally included (bundled) apps is not being disclosed properly, developers hide it in "Custom", "Advanced" and other similar parts of download or installation setups. Quite often people download and install software without checking any of those settings and that is how they allow for various PUA to be downloaded and/or installed through setups of desired programs.

How to avoid installation of potentially unwanted applications?

We recommend to always check "Custom", "Advanced" and other similar settings of any download or installation setup. Quite often those settings include offers to download and/or install additional, unwanted software. Those offers should be dismissed before completing download or installation process of any software. Also, it is important to download software from official websites and via direct download links. We do not recommend to use third party downloaders, installers, Peer-to-Peer networks like eMule, torrent clients, unofficial websites and other tools, sources to download or install software. Additionally, intrusive ads should not be trusted/clicked, most of them are designed to redirect people to untrustworthy websites. Such ads are often displayed on pages related to gambling, adult dating, pornography and other dubious pages. And finally, if there are any suspicious, unwanted or unknown apps (extensions, plug-ins or add-ons) installed on a browser, then they should be uninstalled as soon as possible. It should be applied to software of this kind that is installed on the operating system as well. If your computer is already infected with rogue applications, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
