Hello all, I recently ran Symantec client security and it found a trojan "backdoor.trojan," which it removed. However, after the deletion, my computer started to load and play really slowly. I figure that my computer is already compromised by this trojan and any further attempts to find the virus is useless. I downloaded a program called "Threatfire" and ran a full scan and i found this threat "sequence - Packed/Molebox" found in my System Volume Information folder. I dont know if these problems are related.
It also seems that my computer also runs very slowly and when I check system processes, explorer has a really high memory usuage.
My questions are: Is there a way if I can find out if my computer is compromised by the "backdoor.trojan" and should I format my hard drive (would be hard because I think both of my external drives may be infected).
Thank you for reading.
