The remote host is vulnerable to a local privilege escalation flaw.
The remote host is running AVG Antivirus. This version of AVG is reported to be prone to a flaw where a local attacker can escalate privileges and gain administrative access to the application or system. An attacker exploiting this flaw would need to be locally authenticated. Successful exploitation would result in the attacker gaining SYSTEM access.
Upgrade to version 7.5.476 or higher.
