AntiVirus Information


AntiVirus Information

A computer virus is a piece of code intentionally written to cause damage to software or data files or to attempt to take control of a computer's resources to use it for malevolent purposes. Viruses execute on a given trigger, such as;

  • running a program
  • opening an email
  • or even simply visiting a particular website
 DCU Policy on AntiVirus Management 

DCU Policy on AntiVirus Management

College Policy states that Information Systems Services and users are equally obliged to exercise due care and vigilance in combating the virus threat. It is in the interests of all users to protect the information on their computers as some viruses can do irreversible damage such as deleting your files.

 ISS Services AntiVirus Procedures 


Information Systems Services have invested in comprehensive anti-virus scanning systems to ensure that all email entering and leaving College is scanned for known viruses and infected emails are quarantined or deleted where appropriate. Additionally some file extensions which are known to be associated with viruses are blocked by the College Mail system.


A site license for McAfee is available to all DCU staff. If you wish to submit a software request please click here.

McAfee VirusScan Enterprise combines antivirus, antispyware, firewall, and intrusion prevention technologies to proactively detect and remove malware. It reduces the cost of managing outbreak responses, stops zero-day threats, and mitigates the window of vulnerability—the time between the discovery of a vulnerability and when fixes are deployed

Information Systems Services constantly monitor the DCU Network for evidence of virus infections. Where a computer is identified as having a virus which may spread to other computers on the network, Information Systems Services may disable the computers network connection.

Users who suspect that their network point has been disabled for this reason should contact the ISS Service Desk (5007). Once IS Services support staff have confirmed that the machine is clear of infection the computers network connection will be enabled again.

User Responsibilities

All users should install Antivirus software and follow the instructions to ensure that their computer is protected from viruses. Please contact ISS Service Desk if you have any questions.

 AntiVirus Information for Students 

Windows Defender

If you have Windows 10, you’ll get the latest antivirus protection with Windows Defender. When you start up Windows 10 for the first time, Windows Defender is on and actively helping to protect your PC by scanning for malware (malicious software), viruses, and security threats. Windows Defender uses real-time protection to scan everything you download or run on your PC.

If you have an earlier version of Windows and are using Microsoft Security Essentials, it’s a good idea to move to Windows Defender.

Schedule a scan in Windows Defender

Windows Defender regularly scans your PC to help keep it safe. If you want to set your own scan schedule:

  1. Search for and open Schedule tasks.
  2. In the left pane, expand Task Scheduler Library > Microsoft > Windows and then scroll down and double-click the Windows Defender folder.
  3. In the top-center pane, double-click Windows Defender Scheduled Scan.
  4. Select the Triggers tab, and then select New.
  5. Set your time and frequency, and then select OK.

Microsoft Security Essentials

For students who are not using Windows 8 or 10, Microsoft provide a free anti-virus that can be downloaded and installed from Microsoft Security Essentials.
