IT Security Week | Ransomware - Will your University Data be held to Ransom?

What is Ransomware?

Ransomware is malicious software which when installed on your PC can prevent you from using your PC properly. Sometimes the ransomware locks your PC so you cannot access your programs and files but ransomware can also encrypt files on your PC. The software will then demand a ‘ransom’ or payment from you to get access to your programs or files again.

Ransomware mostly affects PC users, though it is also a growing risk on Macs.

How could my PC become infected by Ransomware?

Ransomware like general viruses can infect your PC from many sources including:
