My friends PC has been infected with the PCQQ ransomware virus. It has become an extension for EVERY SINGLE FILE in my PC. Not even a single file is opening now. It has encrypted every file format and no file now, can be opened even after changing it's extension. There are work related softwares and files related to 3d modelling and design at line here. I also don't have ANY backup for my work files and all the files are encrypted now. I've tried to remove this virus by watching YouTube tutorials but I can't follow some steps as there are files MISSING which the tutorials say I have to delete. How can I resolve this ??? Please help me. She's a college student like me and her 2 years work is encrypted from that virus. Please help.
