Was there ever an answer to this issue? I have used both CCleaner and Chrome for years and never had this issue until the last few months. If I run just the Cleaner (not the Registry cleaner) it removes my LastPass Chrome extension. I end up having to reinstall LastPass... things are good up until I run CCleaner again. If I knew what option to uncheck from the Cleaner list to keep it from removing LastPass I would just do that as a workaround. I will say nothing I have checked looks like it should be removing the extension/app from Chrome. If anyone has had the same issue and figured out a way to fix it let me know because any help would be appreciated. Thanks in advance!
