All of this is a good start, but Task Manager still doesn’t give you quite the in-depth look at a process that you can get with a tool such as the Sysinternals Process Explorer. It includes a number of parameters.

In this two-part article, I’ll recap what I learned in that session and show you how to utilize some of the popular Sysinternals utilities to assist in your malware hunt. After cleaning, no more suspicious processes and system behaved normally: That’s the basis of the “Zero Day” concept – a threat that’s so new there are no protections against it yet in place.
One thing to keep in mind, though, is that some malware will use pseudo random generated process names, in order to prevent you from finding any information in a search. Then you can specify whether it displays handles or DLLs. By using the -u switch, you can get a list of all unsigned files. It’s designed to withstand your efforts to kill it, thus the “reboot and repeat” caveat, which continues until you’ve dealt with all of it.

The problem sysunternals most anti-malware tools is that they rely on signatures to detect the malicious code. We noted earlier that malware is often packed, and the color purple in Process Explorer is an indication that the files may be packed; Process Explorer looks for packer signatures and also uses heuristics e.
An extremely handy feature is the ability to right click a process and select “Search online” to do a web search for information about the process, as shown in Figure 5. For example, you can display the image path name to show the full path to the file toolw connected to the process. You can see this additional information in Figure 3.
