Hello people! I need help! everytime i open my computer, a window pops up saying that yuqhu.dll cannot be initiated. I did a scan with avg and found out it was a worm. i healed it but it still pops up.. I looked at the start up, saw hwyai enabled which opens the yuqhu.dll. it also says that downapup thing. I need help. How do i get rid of this file. My USB also is infected i think bec i ran a scan, and it found two files infected including autorun.info.. please help..
Here are what avg found.. i cleaned and healed them with avg but they dont go away. THey keep coming back. my usb virus also in "f:\"

infection: virus identified worm/downadup path: c:\users\K-TRONICS\appdata\roaming\yuqhu.dll
virus identified worm/downadup path: f:\RECYCLER\(a bunch of numbers)\jwgkvsq.vmx
f:\autorun.inf

this is my hijackthis log.. i dont know if its right. sorry please help. thanks! i've disabled the hwyai yuqhu thing on the startup by the way
