well i can tell you something and i mean no offense, Dr. web didn't help as he suppose to, when type cure on the 2 infected files the button get stuck and nothing happens... i am a PC expert and i had to find out the source of the virus i kept looking, i did the regedit thing and the safe mode thing, dr. web helped 20% and that is allow me to work on my computer without explorer.exe and winlogon.exe, the source was the usb i plugged it in before windows launchs... so avast couldn't stop it, i found the main location of the virus and made an execute on it, it was some place in application files. i got a slow internet so i guess logs application will take some time
