I have Kaspersky Lab license, but it doesn't work effectively. It doesn't detect viruses. If I take flash memory to another computer, Kaspersky can detect viruses. Why it doesn't work?
The Lab licence will not protect you from viruses because this is just an application that ensures communication between computers and master server. Try to download an active solution based on your licence and install it on your computer. Once you do this, Kaspersky will run in the background and provide protection for anything you may attach to PC. Visit the official website to download Kaspersky products.
