I recently got hijacked on my pc. Almost all of my files were encrypted, and was told to pay money to get them back. I downloaded the free version of malwarebytes.org software that helped. But all my files are still encrypted, and I'm very unsure of my pc security. I keep getting messages that Trojans are identified and quarantined, as well as getting messages of outgoing malicious websites. I'm not a big pc user, but need my network to be safe.
