The Error #268D3 is not specifically a virus. However, it is a browser hijacker. While many believe the popup error is a virus itself, it is actually scareware or ransomware to make you believe you have a virus. The scam company then hijacks or holds your browser/computer hostage and/or downloads malicious software on your machine, requiring you to remove it (or call them to remove it).
