In google chrome, advanced settings, clear browsing history, my Hosted App Data will not clear. There are over 2,000 apps in there, most are old and not used or needed. I have discovered that most of these old apps have come from shortcuts I created to have a temporary references, and then deleted. I have deleted the majority of these apps individually, but they came back on the next startup. I use avg tuneup to keep my computer clean, and now I regularly clean the browser. It works fine except for Hosted App Data. Can someone help to clean Hosted App Data, beyond browser cleaning.
