A professional can remove the virus, but not unlock the files. Then it becomes your decision -- pay the ransom, or live without everything that's locked. That's why computer experts recommend having multiple backups of your data. The best protection, never click links or open attachments in emails. If it looks suspicious delete it. Also, keep you antivirus updated. "Immediately you want to pull the plug on the computer, that is how you are going to protect your data from further damage," Strickler says.
