it found 18 differnt things wrong with the machine

these is one it could not get rid of

TROJ_RENOS.IS

and it says its in location

C:\WINDOWS\system32\tazth.dll

so does this mean i just go there and delete this file and everything will be back to normal?

the pop ups still pop up all the time and it hasn't got rid of them 2 windows at the bottom of the task bar
