error messages on my Dell desktop

I've had my dell desktop for about 4 years now. The error
messages I'm getting are "ossproxy" when I go to shut down
the comnputer and when I start up the computer I get
another one that says "cannot execute MAIN. system file
not found"

You've picked up the NetSetter Adware (MarketScore) parasite and need to
remove it. For more details including how to remove it see
http://www.doxdesk.com/parasite/MarketScore.html and also
http://www.pestpatrol.com/PestInfo/N...ter_Adware.asp

Your execute cannot execute MAIN is also the result of malware. So, since
you have or have had at least a couple of unwanted guests ....

When did you last check your system for malware using your preferred
antivirus application making sure first that you are using an updated
current set of viral reference signatures? If you haven't yet managed to
install an antivirus application the download and use Stinger
(http://vil.nai.com/vil/stinger/) and perhaps also F-Prot which will allow
you to scan your system from DOS
(http://www.f-prot.com/products/home_use/dos/).

This would be a good time to download yourself a copy of the free Ad-Aware
SE Personal edition from Lavasoft
(http://www.lavasoftusa.com/software/adaware/) and also SpyBot Search &
Destroy (http://www.safer-networking.org/) and use them to check your
system for other commercial parasites remembering that they are only as
good as when you last updated their reference files. I also use a program
called BHODemon (http://www.definitivesolutions.com/bhodemon.htm that
checks for unwanted Browser Help Objects and SpywareBlaster
(http://www.wilderssecurity.net/spywareblaster.html) which can help
prevent some parasites getting a grip on your PC.

Then there is CWShredder
(http://www.spywareinfo.com/~merijn/files/cwshredder.zip) which is the
best way of getting rid of the many forms of the CoolWebSearch hijacker
details of which can be found at
http://www.spywareinfo.com/~merijn/cwschronicles.html and also
http://www.pestpatrol.com/pestinfo/c/cws.asp..

Finally if you still continue to experience problems download a copy of
HijackThis from (http://www.spywareinfo.com/~merijn/downloads.html).
Create a folder called HJT on C: (not on your desktop nor in your temp
folder) and copy the file you downloaded to that folder. Close as many
applications as you can including all instances of Internet Explorer.
Enable Explorer to see all files and folders (Tools | Folder Options |
View and check "Show hidden files and folders" and uncheck "Hide protected
operating system files") and then run hijackthis.exe and post back the log
to either the HijackThis Forum at http://forums.spywareinfo.com/ or
alternatively http://forum.aumha.org/viewforum.php?f=30 and hopefully this
will enable someone to identify the cause of your problem.
