Conflict with Kaspersky Internet Security and can't close miner if it crashes

[SlavAnd]

I was running a completely stock R9 290, on Windows 7, and I was adjusting the settings to find the optimal performance. I set the worksize to 32 and it crashed my system.

When I got back into Windows I deleted the folder and extracted a new one, and now when I run the executable it gets stuck at "Configuration stored in file 'config.txt'", and I have to restart my computer to close it.

In order to get the setup working I have to have my antivirus disabled, even though I've added the miner to its exclusions and this wasn't happening previously.
