I tried to kill the 134.4kB rubbish by entering 134.4kB in the filter list but they keep coming. I also mark them as rubbish but they keep coming back eg: ICKE when I searched for icke. There are some horrible .zip files with a setup.exe file that brings thousands of malicious files including SurfSidekick3. These destroyed my XP installation and kept me busy for months. I had to install a parallel XP and huntkill all invalid files and bad registry entries. It took out taskmanager and Norton Systemworks and stopped XP starting at all.
The one that got through was in a "V for Vendetta" zip file (Excellent film btw) but most of them are in standard sized .zip files. I put .zip in the filter list and am mostly sticking to audio searches. There should be a filter to reject .zip, .ram and .rm so that most of the nuisances and spyware can be avoided.
