Hi TFL :
Once you are "clean", I recommend you do the following :
1) Your Hijackthis log shows a slightly outdated version of Sun Java,
which can be a Source of getting a "Vundo" infection, which you had;
therefore, uninstall ALL Versions of this program you have, then go to
www.java.com to get the latest version .
2) To reduce the possibilities of "boy" going to Porn Sites, install the
very good & FREE "SpywareBlaster" from
www.javacoolsoftware.com ;
there is a "Tutorial" on this program at
www.bleepingcomputer.com/tutorials/tutorial49.html .
I would not bother using the "System Snapshot" Section .
