I am working with a machine right now (windows xp home) that has been giving me nothing but problems, thus far I have been relatively successful at resolving most but right now i am getting a strange error and i could use a little help if anybody out there has any ideas.
the error is as follows:
"rj8CDyAf.exe - application error
the instruction at "0x7c9118c5" referenced memory at "0x006f0036" the memory could not be read" please help

Actually is? There is no reference to it on any Search that I've done so I'm not sure what if it's supposed to be there.

Anyway no matter what it's not finding the Memory to load properly so it sounds like some kind of infection to me though it may be for some little hardly used specialized application.

Unfortunately without knowing what it's supposed to launch it's impossible to offer any better advice.

I have seen a similar situation that involved a trojan that created executables with randomly generated names.

To see if this is what is happening, try to boot to Safe Mode (not Safe Mode with Networking). When in Safe Mode, search for that file name and rename it (rj8CDyAfTEST.exe). Now restart and see what error message occurs, if any.
If the executable name is now different but the rest of the error is the same, you have a similar infection to the one I ran across on a system several months ago.

Here are the steps I did to remove it.

use this tool: RootKitRevealer (http://tinyurl.com/y3hgq9)
and AVG's free RootKit detector and Remover for good measure: (http://tinyurl.com/35jq2t)

After that you should know if a trojan is indeed involved and which one it is.
Next, I recommend you go here:

TrendMicro has always been my favorite source for virus information and removal.
My second choice would be BitDefender. Here's a link to their extensive library of free removal tools:

There may be a lot of manual steps and time involved to clean everything up and there may be additional investigation involved if the issue remains.

If by chance the rootkit detectors do not find anything, do some additional searches (you may want to do these regardless).
Perform a full system scan while in Safe Mode using AVG Free:

and X-Cleaner Micro:

They may not be need in this case, but here is a very good free on-line scan offered by BitDefender: http://tinyurl.com/aauh5 .
And another by TrendMicro: http://tinyurl.com/2xis .
