I keep getting fake windows security messages and "your computer may be at risk" ballons (in the bottom right of windows - i guess that's what its called). I've searched the forums and tried the things others have.

I've run CWS newest version and hijack this. Also have run Norton 2005 with newest definitions etc. I still get these messages at seemingly random intervals.

Here is my HJT log:

I've cleaned out most of what i didn't recognize or found in the sticky post that could be safely fixed.

Please let me know if there is any other relevant info needed.

Thanks.
