“Avast Secure Browser”.ink Malware

Recommended Posts

So I ran a Malwarebytes scan and It came up saying that “Avast Secure Browser” was a trojan.

I thought it may have been a virus naming itself after Avast’s browser, but when I reset after quarantining, I found that Avast’s browser based off of Chromium was uninstalled.

I scanned 2 days prior and it did not come up. 

Does this mean Avast’s browser was compromised somehow? As I don’t think the browser was updated.

Is there any further action I should take with Malwarebytes beyond the quarantine?

Hello @ErikMouse

This appears to be a false positive. Please restart Malwarebytes and check for updates. Then do another scan and the detection should no longer be there.

Let me know

Thanks

Ron
