Download numbers from the browser store show that several million people worldwide currently may be using the extensions, researchers said.

Avast Threat Intelligence discovered the malware after following up on research by Czech researcher Edvard Rejthar at CZ.NIC, who first identified the threat originating in browser extensions on his system, Avast senior writer Emma McGowan wrote in a blog post published Thursday.

Rejthar set a trap to catch the culprit in action and found malicious scripts coming from certain browser extensions.

Avast researchers investigated further and found that infected JavaScript-based extensions contain malicious code that open the door to downloading even more malware to a person's computer, according to McGowan's post.

Of the two companies, Google at least is no stranger to responding to news of malicious browser extensions.
