Today, we have access to data in abundance, all available on the Internet and ready to serve our various purposes. However, it comes along with a long list of threats, and one of the deadly risks among them is malware. Malware is capable of stealing and corrupting your online/offline data without giving you a chance even to react and prepare for the same. Browsers remain an easy route that malware targets today, and you never know which download or link that you clicked is an invitation to malware files.
Therefore, what do you do to prevent yourself from downloading a malicious file? Well, one of the easiest approaches that you can adopt is to use Browser extensions that scan everything for you. Google Chrome is the most used browser in the world, and if you are also one of the users of Chrome, then OPSWAT File Security for Chrome is an effective browser extension to have.
OPSWAT File Security for Chrome
OPSWAT File Security for Chrome is an easy-to-use browser extension that inspects every download via its MetaDefender Cloud so that you know if your downloaded files are clean enough to access. While scanning the downloads from your Chrome browser, it uses more than 30 anti-malware engines and industry-leading vulnerability scanning technologies. It processes each file or application with a size of up to 140MB that you download on MetaDefender Cloud.
