RansomeWare is probably the worst virus scam that demands a lot of money ($2,000) or all your files are trashed. I already had System Mech Pro installed and was trying out Norton antivirus at the time, and the RansomeWare virus went right past them both. I installed SpyHunter, it caught it and quarantined my kidnapped files safely. At least alowing me to use my computer. It couldn't rescue my quarantined, and now renderred useless document files, and the book I was writing. Fortunately I was able to get many of them restored from a protected back-up on my external Samsung hard drive. All cudo's to 'Spy Hunter'. Thank you Enigma... I eventually had 'Spy Hunter' destroy the quarantined 'Ransome Files'.
