I was recently infected with what I think was a variant of
Trojan.PageStart. It took me about 24 hours to figure out how to get
rid of it. I tried all of the conventional ways that were suggested,
but to no avail. While contemplating hara-kiri I stumbled upon a
suggested fix that said go to Internet Explorer/Tools/Manage Add-ons
and disable any suspicious looking items. One of the items I disabled
was iaak.dll. Instantly the trojan was gone.

I just noticed that it, iaak.dll, is back. I don't currently have any
symptoms of this trojan. I googled for iaak.dll but got zero hits. Is
there any information on what this file is?

I'm running XP home.

Have you tried AVG Anti-virus?  You can find a link to Free (for
personal use) AVG and other tools to remove viruses and spyware here
www.vermontpcsolutions.com/tools_anti_virus.html.  Good luck!

To simly disable the trojan is not enough as it is a dll file it will
automatically restore itself into your system settings.

I would suggest that you disable it using
http://www.startupmechanic.com/ and then search for the file on your
PC (startupmechanic will also assist in pin pointing the file
location), once found remove it and clean your system using
http://www.ccleaner.com/

The AVG virus solution is also a excellent route to take.

You can try several things to attempt to rid your system of this malware.

Firstly, I highly recommend you use an ad-ware/spy-ware removal
application.  I personally use two programs for this task.

Ad-Aware (Free):

SpyBot Search & Destroy (Free):

I have been repairing Computers for 7+ years; I have tried out all the
different firewalls and anti-virus programs out there.

I HIGHLY recommend you pay for your anti-virus.  I have a friend who
was running AVG and was infected with 11 Trojans.

I recommend you buy NOD32 anti-virus.  It has won the most awards and
hasn't failed any ITW virus test in the last 7 years.
