Hi everyone, I've been using ccleaner for several years with no issues, but just recently I've noticed that it will not clean firefox cache. After it cleans it only says 4 files, and always 4 files have been clean. The box is checked. Firefox is not running. I checked that in my start task manager. I thought that there could be a conflict with another program, so I unistalled 3 programs in which one was my AVG internet security. It was around the time I installed it that i noticed the issue, but it still does it. I'm scratching my head here. Any insights or suggestions would be appreciated. Thanks much. P.S. I'm using windows 7 home edition, 64 bit.
