One entry in the HJT log at least has me confused/concerned.....one time it shows, the next time it doesn't;
O4 - HKLM\..\Run: [winshow] "C:\WINDOWS\winshow.exe"

Run HJT again and place checkmarks next to the following;

R3 - URLSearchHook: (no name) - - (no file)

O2 - BHO: (no name) - {44CDB015-C0FC-4268-A704-926B3E02405F} - \
O2 - BHO: (no name) - {B7672BAF-E9A3-49B6-86B2-C81719A18A4C} - C:\WINDOWS\system32\gfprhhne.dll (file missing)

O4 - HKLM\..\Run: [trioService] "C:\PROGRA~1\Freeze.com\3D Falling Leaves\\trioService.exe (I have read some bad things about this website, remove this item entirely from the computer)
O4 - HKLM\..\Run: [winshow] "C:\WINDOWS\winshow.exe"

O16 - DPF: {2D2BEE6E-3C9A-4D58-B9EC-458EDB28D0F6} - http://www.drivecleaner.com/.freewar...eanerstart.cab

O20 - Winlogon Notify: rqrstrr - C:\WINDOWS\SYSTEM32\rqrstrr.dll
