rmy ransomware problem resolved
Thank you Dominic, firstly.
I googled ransomware infection and found a site that suggested MalwareHelp.Org. There I found what program to download and get rid of this thing. My ransomware was different. A "MS Tools Center" window came up listing 30+ at risk files and I was prompted to buy virus protection.
Long story short, after 2 days and running the program twice, I'm good as new.
Thanks for your help!
