Latest Release of OPSWAT Metadefender Chrome Extension Adds Support for Data Sanitization

OPSWAT today announced the release of a new version of MetaDefender Chrome Extension with newly added support for MetaDefender data sanitization technology. MetaDefender Chrome Extension now allows Google Chrome users to scan and sanitize all downloads and files for malware using multiple anti-malware and data sanitization engines. This unique new feature will help users to prevent document-based malware exploits and block unknown threats.

OPSWAT, the industry leader in data sanitization and Content Disarm and Reconstruction technology, has researched and demonstrated the benefits of using data sanitization. Through data sanitization, content that could be exploited by hackers, such as scripts, macros, and hyperlinks, is removed from files while maintaining the files' usability. By introducing this technology to its Chrome extension, OPSWAT is helping users to make sure their downloads are secure and do not contain hidden threats. The extension is available for free for everyone in the Chrome Web Store.

Tomas Hertus, Product Manager for MetaDefender Cloud at OPSWAT, explained: "We added data sanitization technology, also known as Content Disarm and Reconstruction, to MetaDefender Cloud in the beginning of 2017. We are excited to now offer our users this prevention technique in their browsers with the updated MetaDefender Chrome Extension."

MetaDefender Chrome Extension scans all file downloads with 40+ commercial anti-malware engines in MetaDefender Cloud. Scanning with multiple anti-malware engines ensures that more viruses, spyware, Trojans, and other threats can be detected — threats that might be missed by a single anti-malware engine. In addition, MetaDefender Cloud automatically triggers data sanitization for the following file types: PDF, DOC(X), XLS(X), PPT(X), RTF, BMP, JPG, EPS, BMP, and TIFF. Once a file is analyzed and sanitized, a clean version of the file with all exploitable content removed is provided for download.

Hertus added, "Document-based malware attacks have become more and more common, and we wanted to enrich our free services so that anyone can check for and block malware in email attachments and file downloads. This service is very useful for both commercial and home users, as it's important to check any downloads entering your machine. As demonstrated by our Content Disarm & Reconstruction Report, this technology helps to strip all kinds of threats from documents and prevent malware infections."

MetaDefender Chrome Extension is a free product available for everyone in the Chrome Web Store. Visit this page for more information about MetaDefender Cloud.
