@Gaahak: what firewall do you use. Maybe Kaspersky Anti-Hacker ?
There is an issue in this forum where Avast! thinks there is another av (kasp.) but it is in fact the firewall of Kasp.
If not, try to have a look in C Common files, and also in C Documents&Settings where an old map of Kaspersky could be left behind…???
If so, delete this one and do a search for Kaspersky on your hard-drive.
