SDFix - removes worms and trojans

Last night when i browsed my thumb drive i found a folder named new folder and the extension is .exe. i didn't know why but without thinking i clicked on it twice to see what is inside. Just after that it came to my mind that the folder could be some sort of virus. It was true indeed (eventhough i 'm not sure whether it is a virus, malware, spyware or else) but it was harmful since my task manager was disabled..i couldn't run regedit and folder option was missing from the tools drop down menu. After googling, i found this SDFix .


Here is the manual how to use the tool.
SDFix is a program written by AndyManchesta that can remove many different types of Trojans and Worms. You have most likely reached this page when researching a program in our Startup Database and it directed you here to learn how to remove it. If you follow the instructions below, SDFix will remove the known Trojans and Worms found on your computer.
