Explanation
Browser redirection occurs when malware modifies browser settings, the hosts file, or DNS entries to redirect specific URLs to different destinations - in this case, replacing legitimate e-commerce sites with error pages. The fact that the internal website works normally rules out a general network failure. The antivirus automatic update failing over the network (while manual USB update succeeds) is a classic sign of browser/DNS redirection malware that blocks connections to AV update servers. No viruses detected after the update is consistent because the manual update succeeded and the scan ran on a now-clean system. Incorrect time (A) would cause SSL certificate errors across all HTTPS sites. Hijacked email (C) doesn't explain the website issue. Rogue antivirus (D) would typically show fake warnings, not replace sites with errors.
