Malware removal

A variety of tools are available for removing malware, however to guarantee malware is removed, a complete re-installation of the operating system is essential.

When a computer has been infected by malware, you will need to:

1. Remove the compromised computer from the network: shut off and/or unplug  from the network.
2. Notify the Service Desk for assistance.
3. If a complete operating system re-installation is not an option, please follow these steps to try and remove malware:
   • Perform full system scan with Sophos anti-virus software and remove infections.
   • Perform full system scan with third-party malware removal tools-examples include SpyBot - Search & Destroy, Symantec Removal Tools. Third party tools are subject to their own terms of use, it is your responsibility to ensure you comply with their terms of use.
4. Reset all passwords including ones for external sites you may have visited from the compromised computer.
5. Notify the Service Desk that the computer is ready to be put back on the network.

To help prevent systems from being compromised or attracting malicious software in the future:

• Ensure all systems and applications are kept up-to-date.

• Do not run your browser or other applications as root or administrator unless required
