Hi to all==> "Nothing will work with your current version of Kaspersky, because KASPERSKY security is very good in this version, you should do something sensible to solve it "
i can try to explain in easy way...ok
1) Delete all the keys you trying to install or blacklisted :-S
2) Then, Uninstall you current version, even delete folder from Program folder___
Then downlod this fine Registry cleaner for the cleaning your Windows registry-->
http://www.ss-tools.com/files/registry_fixer_setup.exe--> RUN and CLEAN--> DELETE ALL INVALID ENTRIES==> this will also boost your Windows speed by 20% :-)
3) Restart your PC, Fresh install your Kaspersky, ACTIVATE trial version first..
4) After activation, UPDATE your version to latest VIRUS DATABASE for maximum security..
5) right click on Kaspersky taskbar icon--> settings--> Update--->then set, RUN MODE: MANUALL
6) then go this page--> http://www.area51warez.info/softwares/antivirus/10140-kaspersky-anti-virus-database-update.html
download update from here--> follow instructions by click on image, extract update to C:\av-i386-cumul
7) Right click on Kaspersky taskbar icon--> settings--> Update-->settings tab-->deselect+ disable kaspersky lab server--> click add and show the drive where you place extracted folder for Update--> but not trying to update with this, because you have already update in trial version remember...

===> YOU CAN ALWAYS UPDATE YOUR ANTIVIRUS IN THIS FASHION

8) Now go to--> settings--> Network--> click on proxy server settings, then tick + select,
USE PROXY SERVER--> then set use specified proxy sever settings--> write address of any fake useless server like this one ---> 10.0.0.5: port 80 or try anything you want..
9) Now you can Activate your version with previous black listed keys, but remember that, not trying to go very far, like 2010, you can use 2008 keys too, its very good, ok...
10) i hope you are happy now, its a not a secret now, because i have just told you :-)
