Below is a list of proccesses in which are all safe if they are in the right default location. I will be adding the locations, and a definition of the process. Some of the info will come from my head, others will come from one of the two links in which I will place at the bottom of this thread.
I'd like to start with a tip or so, depending on if I think of any. Before you question a service or a process, think about what the words could be shortened as, such as svchost.exe. Does it sound like infectionhost.exe, or does it sound like servicehost.exe?
