Help! I am infected with a virus that Avast said is in c:\windows\system32\drivers\mfl,sys. It said that it is a windows Trojan32 (other). I followed the instructions and deleted as well as moved it to the chest after the second time but it keeps coming back. I have system restore off as well as cleaned all my temporary files as well as my cached files. It keeps coming back and I am lost
Thanks
