Thanks for the info. Only thing is I can't block the extention cause it's mp3 and most of my downloads are mp3s. Don't mind much about them coming up in the searches since I know the two main offending sizes 134.4kb and 60.5kb (although there may be more I am not aware of). But it's the fact that they are a trojan or spyware or whatever that is able to know what I am searching and it presents the offending file in that name is what bugs me and how to find it on my system to put an end to that.
Thanks for your help
