Hi,
The Christopher account is clean now. However, some infections do pass to the other computers in the network. Let's have a look at them too.
- Click Start > Run type "%userprofile%\desktop\dss.exe" /config click OK
- This will bring up a pop up box.
- Uncheck Main log.
- Check Extra log
- check the 5 boxes beneath it.
- Hit the Scan button.
- When the scan finishes the Extra.txt file will be minimised in Taskbar at the bottom of your screen.
- Post it back here please.
===========================
Run HijackThis from each account and post the logs please.
