Guys if anyone of you have hard times in uninstalling KIS 2011 beta follow these steps:

To remove files and folders :

rd /s "%allusersprofile%\Application Data\Kaspersky Lab"
rd /s "%allusersprofile%\Application Data\Kaspersky Lab Setup Files"
rd /s "%programdata%\Kaspersky Lab"
rd /s "%programdata%\Kaspersky Lab Setup Files"
rd /s "%programfiles%\Kaspersky Lab"
rd /s "%ProgramFiles(x86)%\Kaspersky Lab"
del /f "%windir%\system32\drivers\kl*"
To remove registry entries :

reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run /v avp /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ Windows\CurrentVersion\Run /v avp /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KasperskyL ab /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\kl1 /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\kl2 /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\klbg /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\KLIF /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\klim5 /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\klim6 /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\klmouflt /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\R oot\KL_KLIM5MP /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\R oot\KL_KLIM6MP /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\R oot\LEGACY_KL1 /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\R oot\LEGACY_KLBG /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\R oot\LEGACY_KLIF /f
You have to run those commands in safe mode. Running those commands one by one is tough task, so copy the commands to notepad and save remove files and folders commands as kisuninstall1.bat. and save registry entry removing commands as kisuninstall2.bat and then execute them by double clicking it. Remember that this should be done in safe mode.

@Grr, installed KIS with recommended settings.

Yeah, beta products will have bugs and I've came across some serious bug, well it seems that Kaspersky is giving incentives to testers who tell them about bugs. May be a free one year license is waiting for me.... I'm gonna put that KIS 2011 back again on my pc.
