You'll see your anti-malware update itself, discover what uses most CPU, see which applications hog your memory and much more. It's a good idea to keep Process Explorer open in the background for a few days to get a feel for what's normal for your PC based on your typical usage. If you have a dual core processor or better, you can still access the system and kill the process using Process Explorer. Sometimes normal processes can go wild and suddenly take nearly 100 per cent of the CPU time. Many processes use ports to communicate locally it's nothing to worry about.
You can tell because rather than the local or remote address being an external DNS name, both will be your PC's name, a colon, and the port number. Many of the processes you interrogate in this way will be listening to the local machine.
Note down any unknown sites and search for them online. To convert the IP addresses listed into DNS names, ensure that the 'Resolve Addresses' tick box is selected.

System directories in Windows 7 are all well protected by default, so any malware will have to use a temporary directory outside of the system area. Some very old software, like Microsoft Office 2000, has no signature to check, which will lead to an 'Unable to verify' message. It's likely that the manufacturer isn't a verified signer of images. If verifying the image of a seemingly legitimate process produces the message 'Unable to verify', don't panic. When verifying images, pay particular attention to processes that have no entry in the 'Company name' column, those whose description is blank or meaningless, and those whose name is a jumble of letters. If they match, it changes the text to read 'Verified'. Process Explorer uses the running process to generate its own signature and compares the two. Clicking the 'Verify' button verifies the image against a stored signature. Next to the process's icon are the words 'Not verified'. You can verify that the process hasn't been tampered with or infected by malware by selecting the 'Image' tab. To get more details of any process, double-click it. To make it easier to spot such files, you can click the 'Process' column heading until you get an alphabetical listing.
