I think because we're running in safe mode, ComboFix needs a little help.
Highlight and copy the following:
"C:\sUBs\combofix.cmd"
Then go to
Start > Run, paste it into the text field, and then click
OK. ComboFix should start up again, and should produce another log in C:\ComboFix.txt. Post that log for me.
Is normal mode still sluggish? I'm curious if uninstalling one of the antivirus programs was the solution.
