I have had a look at the site and it appears that it (Parasite.js) is benign, indeed friendly.
So where did parasite.js come from? I did not knowingly install it on my computer. Is it a component of Avast or included in some other software. Remember this Comodo HIPS pop up occurred immediately after Win 7 bootup and was the first time I ever saw mention of Parasite.js
I cannot recall whether I had opened my web browser at the time, but could this parasite.js be part of a website armoury?
Thanks for your help.
ps I have done a full bootscan of my pc it is showing clean as well as with Superantispyware.
