Hi Octopia

To run CHKDSK on the command line use the run command from the start menu then type "chkdsk /i" in the box.

How can you be absolutely sure that it's a problem with Kaspersky? It can be caused by a multitude of things. One thing that is worth checking is the available space on your drive. If it's running very low then it's worth having a clear out. I've found that Kaspersky log files can be huge with certain settings, it's worth checking them and deleting the older ones to free up some space as well as clearing out some of the usual suspects such as the temp internet files.

Personally I don't run the likes of CHKDSK unless I suspect a problem, which is usually no more than twice a year. Excessive use only exerts unnecessary strain on your drive and will reduce it's life span.

If you find it still won't complete, boot Windows in Safe Mode (Press F8 while booting) and try it from there.

Welcome back.
