Yes, a BIG one...Where is your anti-virus program and where is your firewall. You are not running either one. You are very lucky you don't have many more infections on the computer.
There are some very good Free anti-virus programs, download ONE and install and update it.
Antivir
Avast
AVG8
You choose. But you MUST install and use an anti-virus program. Same goes for the firewall. There are several good free ones out there, also of course Windows XP has the built in firewall.
Run HJT again and place check marks next to the following entries if they remain:

O2 - BHO: VisualTool - {F3A54897-9E68-B11E-A37A-4D1422CE9CAA} - C:\Program Files\VisualTool\VisualTool-2.dll (file missing)
O3 - Toolbar: Mirar - {41B35E5E-FF7A-410E-9DBF-2485FB45C003} - C:\WINDOWS\system32\windg77.dll (file missing)
O9 - Extra button: (no name) - {CD67F990-D8E9-11d2-98FE-00C0F0318AFE} - (no file)
Once you have placed the check marks click the Fix Checked button.
Exit HJT.
Reboot.
Run another HJT scan and post the log. Please don't print it in italics or color, that makes it very hard to read.
