Hello friend, I have windows XP that has become infected with RECYCLER folder also called Trojan horse. This Virus always run in the background. I tried a lot of thing but I have not been able to find solution. One of my friends suggests me to use Combo Fix to come out this problem. I tried that also but not successes. This folder propagates itself by copying RECYLER folder to the root of all media or drive. My USB drive is also infected with this. It also run registry key. It rename the folder also.What is the step to come out this problem?
