iexplore.exe virus

Has anybody encounterd the iexpolre.exe virus this always pops up with a screen view downloads-Windows Internet explorer       View and track your downloads.

It asks for you to run or save the download but then pops up with the same download screen so it just goes in circles, when asked to connect to support desk to gain acsses to my computer it asks to run the program and when I hit run it repeats and does not let anyone else log-in so how do I get rid of this virus.
