My PC has been attacked by the virus issue since yesterday. Hopefully, Norton blocked all the attack attempts. But I don't know why this afternoon, the attacker used some tools running my PC, and it seems the virus already spread on my system. The "Decrypt_instruction" links and files are created everywhere!!!
I noticed that the virus doesn't encrypt my important documents. And I already delete all the "Decrypt_instruction" links and files. Norton checked and deleted a high risk .exe file. So, I am just wondering what should I do next to make sure my system is safe. Unfortunately, my last back up is three month ago. My most of important documents are created around this two months.
