***Reposting a problem originally posted in December but not resolved***
My son's computer was recently infected with a pretty nasty bit of malware, which I successfully removed with the wonderful assistance of Bleeping Computer folks. The machine is running Windows XP Media Center edition SP3 with all available updates, and it is connected to a wireless network using a Linksys compact Wireless-G USB adapter. The router is Linksys Wireless-G, model WRT45G, with the firmware recently updated.
Now that the malware is gone, sometimes (but not always) when I restart the machine, I get the message "Access violation at address 00000000", which seems to be coming from the Linksys Router Monitor. When I do get that message, then another message "PCARMDrv.exe failed to initialize" appears when I shut down the machine. However, the machine does connect successfully to the internet, and there don't seem to be any further connectivity issues while it is running. There are two other machines on the network and they are having no problems, so Iím reluctant to mess around too much with this. (I didnít set up my network and know almost nothing about it.)
When I posted this issue earlier, the BC helper suggested that I run msconfig and check the system startup, then look for PCARMDrv.exe and uncheck it. So I ran msconfig, but PCARMDrv.exe was not listed. And now I have an additional problem. While running msconfig, I also looked at the Services tab and clicked "Hide Microsoft services", examined the list, then de-selected "Hide Microsoft services" and hit OK. Even though I made no changes, somehow this put it into Diagnostic or Selective Startup mode (I forget what it was called). I got a message about access denied and needing administrator privileges, even though I was logged in as a user with admin privileges, so I restarted the machine and set it back to Normal mode. However, now every time I restart the machine, I am prompted to choose which operating system I want to start, and the list contains two identical entries: Windows XP Media Center Edition.
So, how can I get rid of both these issues? Neither one is preventing us from using the machine, but I donít think I should ignore them. Thanks!
