Hello,
I just downloaded CCleaner 2.10.618 from FileHippo today. The installation stopped near the end and Comodo Firewall notified me that a file called GLB1699.tmp was attempting to modify Mozilla Firefox. I've been using CCleaner and I don't ever remember it running any .tmp files that were modifying my Firefox. Has anybody else seen this and can the Piriform team comment on what this GLB1699.tmp file is? I couldn't find a single instance of this filebname in any search engine.
After doing a search of my computer, it seems the full name of the file is GLB1699.TMP-189C30B4.pf and it is running out of the \WINDOWS\Prefetch folder.
