Sorry, the server I'm using appears to be having some issues. No matter, I'll just have you create the file manually. It's quite simple. First, copy everything in the code box below (highlight, right-click, select Copy)...
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows]
"AppInit_DLLs"="avgrsstx.dll"
Open Notepad and paste the text there (Ctrl+V). Then go to File > Save As. Click on the Save As Type arrow and select All Files. Save the file to your desktop as fix.reg and double-click on it. If you are asked to Run or Cancel, select Run. When asked if you would like to add the file to the registry, click Yes. You can then delete the file.
Also, did you try searching for that rtrbos file?
