I blasted Kaspersky for deleting CCleaner and refusing to restore it - well, restoring it and deleting seconds later. The file in question is CCleaner 533 and I have since learned that it is indeed corrupted by a virus. So apologies to Kaspershy for going off half cocked with my public criticism.

I just uninstalled it. It is so intrusive for no reason.
The secure browser runs apparently at random and blocks my password manager from filling in user id and password. About every other web site an alert screen pops up saying that the site is not properly authenticated - sites as common tacos. It is a royal pain to pause to authorize proceeding. Just now a scan found the installation file for C Cleaner which I have used for years.
When I tried to restore the file, the stupid software put it back in the original location and 5 seconds later removed it again. I am just fed up with this software no matter its exalted ratings.
Review about: Kaspersky Lab Internet Security Antivirus.
Reason of review: constant needless alerts and actions.
Monetary Loss: $55.
Preferred solution: Full refund.
