That will depend on what the virus is. Did Symantec already identify the virus?<br />

Yes it has but we are tying to locate the port and site from which it was downloaded.

Can you post the name or some description of the virus. Without knowing that it will be hard to know. <br />
<br />
Otherwise you just have to review your open network ports, password &nbsp;policy, file creation dates and times, and network logs (e.g. ftp server, web server etc.) and hope to find something around the time of the infection. The time of infection can be deduced by looking at all files created by the virus and checking dates and times.<br />

Antivirus

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.

OS Security

System Utilities are a type of system software used to support the computer infrastructure, distinguishing it from application software which is aimed at directly performing tasks that benefit ordinary users. Commonly used utilities include password managers, disk managers, system monitors, data synchronization tools, security and antivirus software and editors.

System Utilities

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.
