It is simple areas that could be potential vulnerabilities, such as auto run for removable media ect.. Once you change these settings with Kaspersky, those changes will remain in effect even if you decide to get rid of Kaspersky, in which case you would have to remember and manually revert them back if you so chose to do so. I would advise against using Kaspersky to make these changes, although you could read up on each one for a better understanding on how they could be a vulnerability.
