Virus detection and removal Nimda_E analysis mouse out of control and virus intrusion

Recently, my mouse was randomly moved without listening to the command. I suspect there are viruses or Trojans, so I used Kingsoft drug overlord, iparmor5.33, And the cleaner to scan and kill none of them.
Problem. However, I found several tasks with no paths, versions, and information under "system information-running tasks" (see the attachment for details ). I don't know whether this is the case or not. Could you tell me?
What are these three tasks, can they be deleted, and how can they be deleted? (2002-3-3)
