You observe that your network gateway shows high levels of network activity even though you have closed your e-mail client, Web browser, and all other programs that access the Internet. What types of malwares could cause such symptoms? What steps can you take to check whether malware has gained access to your system? What tools can you use at each step? If you identify malware, what ways might it have entered your system? How can you restore your PC to safe operation, including the special software tools you may use?
