Geez, if you don't know, how can you expect someone else to.

It's not which program was downloaded, it's which program was installed/used(some may not install but could write a register entry) that matters. However, if the program was installed, you should be able to find some trace of it in START->PROGRAMS, etc.

Try using RegCleaner (do a SEARCH, the url is here!) to see if it finds a register reference to a file(s) which does not any longer exist on your hdd, etc.

Good luck.
