How do I protect my computer from Ransomware?

Esther Silver's picture
  • If you receive a Ransomware popup or message on your device alerting you to an infection, immediately disconnect from the Internet (wifi or unplug wall connection) and external drives to avoid any additional infections or data losses.
  • Always use antivirus software and a firewall. It's important to obtain and use antivirus software and firewalls from reputable companies. It's also important to continually maintain both of these through automatic updates.
  • UCSF IT provides client security software (anti-virus and firewall in one) free of charge to UCSF faculty, staff, students, and researchers: http://software.ucsf.edu
  • Maintain a current patch level for any operating systems and applications.
  • Back up service (CrashPlan Pro) is offered at no additional charge, to all ITFS supported desktops and laptops as part of the ITFS Basic Support, and to UCSF Medical Center supported laptops - https://it.ucsf.edu/services/crashplan
    UCSF staff, faculty, and students can purchase a CrashPlan subscription for personally owned computers at a discount.
  • Exercise caution. Don’t click on links inside emails, and avoid suspicious websites. If your PC does come under attack, use another computer to research details about the type of attack. But be aware that the bad guys are devious enough to create fake sites, perhaps touting their own fake antivirus software or their de-encryption program.
