Yesterday, Kaspersky company blacklisted a  lot Kaspersky keys. I have some active Kaspersky Internet Security 2009 Keys, but all of them are only work in Chinese version. BUT, you can change the languge file and use them in english version.Here are some working keys for you all:

kaspersky antivirus 2009 key = kaspersky antivirus  8 = KAV 8

Kaspersky internet security 2009 =Kaspersky internet security 8.0 = KIS 8

kaspersky internet security 2009 (sch)-20090726-04e4e3c7

kaspersky internet security 2009(sch) -20091012-0459b7a9

kaspersky antivirus 2009 key(sch)-20091211-0459d0d1

kaspersky antivirus 7.0 key (en)-20090620-03283c5e

For the keys who have been signed (sch), if not working in your english version, you should do some changes(before you install you new kaspersky keys, you should delete the old blacklisted keys first)
1 Close your Kaspersky.
2 Open C:\Program Files\Kaspersky Lab\Kaspersky Internet Security 2009\Skin\loc change the file name “en” to “sch”
3 open the Registry . Start->Run->Input regedit then find HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\protected\AVP8\environment ,on the right, you can find Localization, change the name “en” to “sch”. Close.
4 Restart explorer.exe, or restart your computer.
5 You can use the keys FREE!Good luck.
