Have you made a backup of your system?

no i had n't backed up my system.

You might enable Windows Defender and let it have ago at your virus. It is pretty solid when it comes to removing infections. I am not sure if it would do a better job than Kas though.

By the way, stick with the version of Flash that comes with Win8--at least for now. My understanding is that this version is the one that currently works best on Win8.

Also, it may not work, but you could try doing a system restore--assuming that you have created at least one restore point dated prior to your problem. Note that system restore is not highly regarded when it comes to removing viri.
