WannaCry Virus in General Discussion Posted October 21, 2017 Addendum: Never pay. Majority of times, there is no intention of ever restoring your system, and sometimes they don't even store (or generate!) the means of doing so. Furthermore, should you find yourself infected with something, the first step is always to stop what you're doing and not touch anything (unless you've got a recent enough backup you can revert to). Such as with WannaCry, the only potentially working recovery provided that I know of could only do its job if the computer had not been turned off in between.
