<p>
|
|
Ace Portables contacted AZ Computer Guru LLC after their financial institution requested verification that company workstations were free of malware. Upon investigation, we determined that the previously installed antivirus software (McAfee) had silently expired, leaving the machines unprotected.
|
|
</p>
|
|
<p>
|
|
We removed the expired McAfee installation and deployed <strong>Bitdefender GravityZone</strong>, an enterprise-grade Endpoint Detection and Response (EDR) platform, across both company workstations. During the initial security scan, Bitdefender detected and automatically deleted a malicious browser extension containing a Trojan on one machine. Both machines have been fully scanned and are confirmed clean with no active threats.

|
<li><strong>Deployed enterprise endpoint protection</strong> — Bitdefender GravityZone EDR was installed and configured on both machines, providing real-time threat monitoring, behavioral analysis, and automated response.</li>
|
|
<li><strong>Malicious extension deleted</strong> — The Trojan-infected browser extension was automatically detected and removed by Bitdefender during the initial scan.</li>
|
|
<li><strong>Extension blocked globally</strong> — The malicious extension has been added to our managed blocklist, preventing it from being installed on any endpoint under our management.</li>
|
|
<li><strong>Full system scans completed</strong> — Comprehensive antimalware scans were run on both workstations. Both returned clean results with no further threats detected.</li>
|

Both Ace Portables workstations have been verified clean and are now actively protected by enterprise-grade endpoint security. The previously unprotected state caused by the expired McAfee subscription has been fully resolved. The detected Trojan was automatically removed before any confirmed data exfiltration occurred, and preventative measures are in place to block future threats.
