Watch out: new computer virus!
Recently there has been a computer virus that took down many NHS trusts. The virus is called wannacry, and is a type of ransomware.
Here's what you need to know about it...
Ransomware is a type of computer malware that encrypts files, disks and locks computers. The hacker then demands a ransom for decryption tool which has to be paid within a stipulated time in the form of bitcoins.
The good news is, if you run windows and have updated recently you are safe, but it's still important to always follow these best practice steps with any computer...
- Make regular backups of important files on some form of removable media like a USB drive. Don’t keep the USB drive plugged into your computer!
- Do not open attachments from unknown sources and do not download or open unauthorised software.
- If you suspect any unusual hard drive activity on your computer, immediately shut it down and disconnect from the network. If your computer is managed by an IT company, report to them. If not, then we recommend booting into safe mode and running a full antivirus scan.
- Do not enable macros on office documents that you do not trust.
- Keep your software and operating system up to date by installing automatic updates as soon as you see them.
Just remember, anything that looks suspicious- probably is!
