Gstatic is a genuine domain used by Google that hosts images, CSS, and javascript code to reduce bandwidth usage online.
Gstatic isn’t a virus and will not damage your PC in any way. It’s completely normal to see the Gstatic URL while loading a web page. It means Google is processing the content on the page.
However, if you begin to see harmful pop-ups from a site claiming to be Gstatic, it could mean your PC has been infected with malware. It’s advisable to conduct a full system scan using a robust antivirus scanner, like Norton, to eliminate any threats.
