cannot load "ddayv.exe" after virus chicking computer

When I start my computer I get the message cannot load or run ddayv.exe.

This came up after I did a virus check of my system.
Orriginally the laptop began to be sluggish and when closing various windows -the system toolbar and systray would disappear.
I have run AVG and adaware (which had a problem and I had to reinstall). In searching, I have installed HIJACK THIS and have made a copy of the log and was wondering if someone could take alook at this:

Hello, and welcome to the forum.

My name is Simon V., and I'll be glad to help you with your computer problems.

Step 1

Please download and install CCleaner.

Open CCleaner. On the Windows tab, leave the default options alone.

• On the Applications tab, check (tick) all the boxes except Saved Form Information. This will remove all your saved passwords if you leave this box checked.
• Click on the Run Cleaner button at the bottom right hand corner.
• When the cleaner has completed, click Tools in the Left Pane.
• Verify that Uninstall is highlighted in color, or click on it.
• In the lower right, click Save to Text File.
• Pull down the arrow at the top of the Save dialog and choose Desktop as the location.
• You can leave the filename as install.txt.
• Click Save, then exit Ccleaner.

Step 2

Please visit this webpage for instructions for downloading and running ComboFix:

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Post the log from ComboFix (C:\Combofix.txt) when you've accomplished that, along with a new HijackThis log and the CCleaner Uninstall List.

Do you still need help?
