When you visit http://search.yahoo.com in IE7, a bar pops up at the top of the page asking you if you'd like to set Yahoo! search as the default search option in the IE7 search box. On clicking the orange "Choose Yahoo!" button and saving the file to my HD, NOD32 shows the red "threat detected" window and says that ysetsearch.exe is "probably unknown NewHeur_PE virus". The strange thing is, once I have downloaded the small file to my desktop and re-scanned it, NOD says that the file's clean. Can anyone else confirm/deny this behaviour?
