Given the apparent resolution of your problem, I'll
re-post the information I gave you as an official
answer. It's not clear from your response whether 
you ran a virus scan or installed and ran the 
programs I recommended for rooting out malicious
spyware and adware, but I would strongly encourage
you to utilize these options, given the considerable
benefits to your system, and the fact that they are
all free options.
If the problem recurs, or if you have questions 
about the programs I recommended, let me know.

APPA3A3 returns no results in a Google search. It seems safe 
to assume that you can delete this file without loss of anything 
of use. It's also possible that this file is part of a trojan or 
spyware. If you are unable to delete it, due to its being in use, 
try rebooting into safe mode and delete it that way. Once it's 
gone, I'd strongly suggest running a virus scan on your entire 
system. If you have no antivirus software, use a free online  
service, such as: 
 
Bit Defender:   
http://www.bitdefender.com/scan/licence.php   
   
Trend Micro:   
http://housecall.trendmicro.com/housecall/start_corp.asp 
 
 
You may also benefit by downloading and running the   
following three programs which search out malicious adware,  
spyware and BHOs, or Browser Helper Objects:  
  
Ad-Aware:

Spybot Search & Destroy:  
http://spybot.eon.net.au/  
  
BHODemon:  
http://www.definitivesolutions.com/bhodemon.htm  
 
 
You may also need to ascertain that the necessary Windows 
file, shell32.dll, exists in its proper location in: 
C:\Windows\System\ 
but if you cease getting the error popup, and everything 
seems to be working, this may not be a problem.
