How did HookSpoofer infiltrate my computer?

HookSpoofer is distributed through various bundlers, which are packages that combine two or more files into a single entity. Bundlers hosting HookSpoofer can be found on various websites, including file-sharing platforms, torrent sites, and software download portals.

Cybercriminals can also distribute bundlers through phishing emails or malicious advertisements. Users may end up downloading these bundlers through various means, including clicking on links in phishing emails or downloading files from unreliable sources.

They may also inadvertently download the bundlers when downloading legitimate software from a compromised website. Once the bundler is downloaded and executed on the victim's device, HookSpoofer is installed and begins its malicious activities.

How to avoid installation of malware?

Use reputable antivirus software and keep it updated. Only download software from reputable sources, such as the software developer's official website. Be cautious when downloading files and programs or clicking on links received through unsolicited emails or messages. Do not trust ads on shady web pages.

Keep your operating system and other programs up to date with the latest security patches. Avoid connecting to public Wi-Fi networks. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
