Passwords sometimes not asterisks

Hello - Sometimes when I type my passwords into forms, sometimes they don't display as asterisks initially. Either nothing is displayed or they show up initially as vertical lines. When this does hapen, most of the time they eventually render as asterisks. I have been chalking this up to maybe my computer is busy or slowed due to new slower wireless network. However, I found a file called service.exe in one of my folders and I do not know what it is, which made me suspcious. Also one day a while back I clicked on the wrong website and it turned out to be one of those popups that then try to force you to install something by not giving you another option. This seemed to be just before the weird password type-in installed inccoredtly. Attached is a copy the results of running HijackThis. Also, just to note that I have shut down most of my processes, but I see a number of odd programs still running in my list of processes in Windows Task Mgr. Thank you fo for any help you can provide.
