sorry to give u wrong info its actually ISTDNLDR-B-UPX which is the name a/v( version 4.1 home ed ) gave it but in virus chest it named it with the dll so i wasnt sure. I also did the google search which led me guess where?, back to the Avast site and there it was but wow so many, so im still wondering is there anything ive gotta worry about as a result of having had this bug on my system?
