Hi, I am curently experiencing an issue where winlogon.exe is running 50% of my CPU constantly - it is not fluctuating at all. When I logged in today, I entered my login info and my wallpaper flashed briefly before returning to the login screen. When I logged in again it worked normally. Now my virus-scan is warning me of changes to my shell32 and hosts files (attached), and I have not run WindowsUpdate today. There also are "Generic9.BGEU" trojans in a couple of archives. Lastly, streaming video is having a lot of problems, possibly because of the CPU hogging by "winlogon" but I thought I would mention it for completeness' sake. Are there any new viruses, etc. out that are related to winlogon.exe? When I "logged in" twice, did I inadvertently provide a hacker with my logon info?? Can I manually stop winlogon.exe and have it run normally upon reboot?
