OK so if you want to get rid of it you can not rely on any antivirus (yet).
I downloaded Total Commander, opened regedit (start->run->regedit->OK), click CTRL+ALT+DEL, in task mamager end the task named EXPLORER.EXE (your explorer will shut down, i.e. desktop, taskbar).
Now go into regedit under [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run] delete the entries with kava,ckvo or similar.
Go to [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] set Hidden to 1.
Go to [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and delete "NoDriveTypeAutoRun" = 145
Open your Total Commander. Go to Configuration->Options->Display. Enable Show hidden/system files.
Go to each of your drives with total Commander and delete the suspicious files(not folders). The names vary from system to system, so i opened my secondary partition(D:) first and the only files there were those infected so i deleted the same files on C:
Now you can open your windows explorer.
To further clean your PC go to C:\Windows\System32\. There delete the files named kavo or ckvo
