Subject: how do I know what processes to end in task manager
If you're suspicious of a particular process, look it up via a search
engine. And get Process Explorer http://www.sysinternals.com/Utilities/ProcessExplorer.html
You probably won't understand how to use it; I'm really posting the link
for others who find this thread.
If the process is malware, you're going to have to do more than just end
it. You'll have to hunt it down and then kill it and its brothers too.
