explorer.exe - High CPU Load

Hello, i need help please. Whenever i run the file deletion module of CCleaner, my explorer.exe begins to eat up 80-99% of the cpu performance. According to mark russinovich's process explorer it seems like SHLWAPI.dll is causing this behavior. Any advices?

Edit: I think that fixed the problem:

[...] The SHLWAPI.dll Ordinal was 505 in this case. I got rid of half the problem by right clicking on the C drive in Explorer and then selecting Properties. In the Properties dialog box, I unchecked "Allow Indexing Service to index this disk for fast file searching", and then applied it to all subfolders and files. [...]
