Space Sucking Files!!!!!!!

Whilest reading this great forum i came across a great app called 'what size'
and as my hard drive is looking rather full i downloaded and ran it, only to find a space sucking file containing 18GB!!! of what i dont know.
I am not able to locate it useing spotlight am i the first OSX user to become infected with a virus? i do hope not its nthe main reason i switched.
Advice please ladies and gentlemen.

What is the file called?

If you want to view the file in the Finder, just select it in WhatSize and hit Command+Shift+R (for reveal) to see it in the finder.
From there you could drag it to the trash.

But I'd make sure it isn't something important first, maybe post back the exact filename first before deleting, if you're unsure whether it's needed or not.

Dude, calm down. Just use OmniDiskSweeper to find out if it's a system file:
