"How to use Kaspersky for Lifetime without Patch"
Generally Kaspersky provide us 30 days trial period on its Anti-virus Product. So there are the few steps that you have to perform when your trial license going to expire after 30 days for getting a new trial license :
1. Delete old key and turn off self defense (Settings-Options in kaspersky and turn off Enable self-defense, and click OK).
2. Open Registry editor (click start in windows menu then goto run and write regedit and click Ok) and go through these :
For 32bit OS: HKEY_LOCAL_MACHINE \ SOFTWARE \ KasperskyLab \ protected \ AVP9 \ environment
For 64bit OS: HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ KasperskyLab \ protected \ AVP9 \ environment
3. Right look for PCID and right click and modify three or four last numbers or letters example : (8F10C22F-6EF6-4378-BAB1-34722F6D454)
and enter any other three-letter four-number and close the Registry Editor.
4. Right click on Kaspersky icon in the task bar and choose exit.

I am Gokul krishnan of cnss 8D. Really according to me Kspersky is a great anti-virus and you should not minimise it in 30 day trial version but you must purchase a full virsion for just Rs550.
Let the money go but it is the best anti-virus ever. HAPPY KASPER DAYS!!!

Well i have already tried this patch a month ago and i am sure that you will be blacklisted once you connect to the web.So better use Avast or Avira.Avast is the best when updated and it doesn't slow down your computer too.
