Last night, my anti-virus program picked up a virus called W32.Cridex!gen5. I though it is already removed by my anti-virus, but today after I booted up my computer, I can still get the virus warning about it from the tool. It says that it can only quarantine it but can’t remove it. That makes me feel really nervous. Can it damage my computer somehow? How about my information saved on the system? Can they be stolen? What should I do?

This Trojan can help cyber hackers to connect to the corrupted machines remotely without being known by computer users.
