Just ran CCleaner again. No zip files, but it now shows Content.ie5 containing 27 random .png files and something called TSleepinfo_EXE.
TSleepinfo_EXE is probably this files tsleepinfo-exe that you downloaded twice. Nothing to worry about.http://systemexplorer.net/file-database/file/tsleepinfo-exe/7252808
The png images are all replicates of a picture from a newspaper article I read using Firefox, not sure why they've appeared repeated in Content.ie5!
Everything pages you download or read on the internet goes to the Temporary folder.
If you do not want to keep anything the temporary folders can be emptied when you close Internet Explorer.
Under Tools, Internet Options, Advance tab.
Place at "Check mark at: Empty Temporary internet file folders when browser is closed."
