I'm sorry for the delay in replying.
I haven't heard of Recyclers I'm afraid, and although there are ways of deleting files either in Safe Mode or using a delete file utility, (called MoveOnBoot), I don't dare suggest you try it just yet.
(I've just seen reefurb suggest the Safe Mode method and I agree, except I am not sure about Recyclers).
These forums have a Virus & Security alerts forum where there are virus experts that can help. They have a much bettter idea at these things than I do. The link is listed on the left, or you can go here;
I suggest you post a question there about these infections Norton has found.
But before you do, have you also tried different programs to scan your computer? Norton is a good anti-virus, but does not scan for spyware or adware, and you really need other sotware for those. I have listed below what I use;
DOes Norton's include a firewall? Or are you using Windows XP SP2 firewall? If not, you can get a free one called ZoneAlarm from http://www.zonelabs.com
An anti-adware program. Free program is Ad-Aware SE Personal from http://www.lavasoftusa.com
And 2 spyware programs, Spybot Search and Destroy from http://www.safer-networking.org/
and SpywareBlaster from http://www.javacoolsoftware.com/spywareblaster.html
I am also trying out Microsoft's new, (or newly acquired), AntiSpyware software in addition to all the above. It seems ok so far.
Make sure your Windows Operating System, (OS), is up to date. To do this, goto Start, and click the ?Windows Update? link. Beware, if you have not been to Windows Update before, there may be a lot of critical and other updates your OS needs to download.
All of these anti-malware programs (except the firewall), need to have their virus/adware/spyware definitions updated as soon as they are installed, and then each one used to scan your computer.
BTW, sorry about all the studying I got you to do,
