PUPs (Potentially Unwanted Programs) and Browser Hijackers are Unlikely to be Installed Knowingly

PUPs and browser hijackers are often distributed through various shady practices that exploit users' trust and lack of vigilance. These distribution methods can be deceptive and unethical, posing risks to users' online security and privacy. Here's an explanation of how these unwanted software types are typically distributed:

  • Bundling: One of the most common methods is bundling, where PUPs and browser hijackers are packaged with legitimate software downloads. Users often download and install software from trusted sources, assuming they are getting only the program they intended. However, during the installation process, they might overlook or rush through the setup, inadvertently agreeing to install additional, unwanted software. These bundled PUPs and browser hijackers may be pre-selected for installation by default, making it easy for users to overlook them.
  •  Deceptive Websites: Shady websites, often hosting pirated content, adult material, or illegal downloads, are notorious for distributing PUPs and browser hijackers. Users may visit such sites and, knowingly or unknowingly, download software or click on deceptive ads that trigger unwanted downloads. These sites may use deceptive tactics to lure users into clicking on download links or pop-ups.
  •  Fake Updates and Installers: Cybercriminals and shady advertisers often create fake update notifications or installers that mimic legitimate software or system updates. Users may be tricked into downloading and installing these fake updates, only to find out that they have installed PUPs or browser hijackers instead.
  •  Email Attachments and Phishing: Some PUPs and browser hijackers can be distributed through email attachments and phishing campaigns. Users may receive seemingly legitimate emails with attachments that, when opened, lead to the installation of unwanted software. These emails can impersonate reputable organizations or individuals, making users more likely to fall for the scam.
  •  Social Engineering: The social engineering tactics are used to trick users into taking actions that lead to the installation of PUPs and browser hijackers. This can include enticing offers, fake giveaways, and convincing messages that encourage users to download or install software without fully understanding the consequences.
  •  Malvertising: Malicious advertising, or malvertising, involves delivering malicious software through online advertisements. Users may encounter infected ads on legitimate websites, and clicking on these ads can lead to the download and installation of PUPs and browser hijackers.

In summary, PUPs and browser hijackers often leverage deceptive and unethical distribution methods to infiltrate users' systems. To protect against these unwanted programs, users should be cautious when downloading software, keep their operating systems and software up to date, use reliable anti-malware tools, and practice safe online browsing habits. Additionally, reading user reviews, paying attention during software installations, and avoiding shady websites can help mitigate the risk of PUPs and browser hijackers.
