More often than not, victims unknowingly install viruses on their own computers. With the complexity of today’s malware, you may need to reinstall your operating system and restore your files from a clean backup in order to completely cure the infection.
How will you know?
If something just doesn’t seem “right” on your computer, it could be infected with a virus or other malware. Frequent pop-up ads, redirected Internet searches, unwanted browser tool bars, fake antivirus messages, and an all around slower system are all signs of a possible malware infection.
Proactive steps you should already be taking
- The University recommends that you install McAfee VirusScan software on your computer. Regularly use the program to scan for viruses.
- Remove all peer-to-peer (P2P) file-sharing programs.
- Regularly back up your hard drive to an external source using programs like Apple’s Time Machine or Window’s Backup and Restore tool.
- Remove as much confidential or personally identifiable information (PII) from your computer as possible. Files containing confidential PII must be encrypted. (UD encryption help pages)
Steps to take after you suspect an attack on your computer
- If you have reason to believe that University related confidential or personally identifiable information (PII) has been viewed or taken, immediately contact firstname.lastname@example.org so IT can begin their investigation of the incident.
- Immediately disconnect your computer from the UD network so you don’t risk spreading the virus to other computers on the network.
- Run McAfee VirusScan to remove any viruses or malware that are infecting your computer.
- Contact your department’s or college’s IT staff or the IT Support Center for assistance scanning your computer’s drive for confidential PII.
- Your department’s or college’s IT staff or the IT Support Center can also advise you whether or not the specific malware requires you to wipe clean your Mac or PC’s hard drive and reinstall the operating system using a clean backup of your drive, possibly from a few weeks ago.
- Both students and staff members can take their computers to IT Client Support & Services, Smith Hall lower level, for a thorough and comprehensive virus cleanup. Contact the IT Support Center at (302) 831-6000 or submit a Help Request Form to request an appointment.
