Hello everyone. I am using Windows XP Home Edition. Before today, my computer ran perfectly and rarely crashed. Well today I installed a game I bought(Knights of the Old Republic if it matters) and began playing it. The game crashed on me a couple times, and my computer completely froze up when I tried to minimize the game. When I restarted the computer, my backround didn't cover the whole screen, and over the backround was a black backround with text saying something about my computer being infected, but I couldn't read it because of the icons on the desktop. Then a window of a virus scanner I had never heard of popped up telling me I had 10 infected files. I thought it was some pop up ad and closed it. My computer froze again shortly after and I restarted it again.

During the restart, I received an error message while Windows was loading(I don't choose a user, there is only 1 so it goes to that by default) saying "Explorer.EXE - Application Error: The application failed to initialize properly(0xc0000005). Click on OK to terminate the application" so I clicked ok and it loaded up the backround of my desktop and that is it. No taskbar or icons. So I restarted my computer again, and again I got the same message, with the same result. I am able to start programs through the Task Manager, but Explorer won't start and I get the same message. I installed McAfee Virus Scan Professional(2005 version) and ran a virus scan which showed no virus'. I have been messing with stuff all night through msconfig. I am able to boot up in Safe Mode and access files that way. I uninstalled the game but it didn't help.

Can somebody please help? I appreciate anything anyone can offer. I just hope I don't have to use the re-format CD(Which I don't have with me). Thanks in advanced.

Are you using these basic security programs?
(They're all free.)
aČ free
ewido security suite
Spybot S&D

These 2, will help prevent spyware/malware from being installed in the first place:

Download them, update them, and then run them.
These programs, updated and used regularly, will do a lot to keep your computer clean of spyware, trojans, keyloggers, browser hijackers, etc...

When installing ewido security suite, under Additional Options uncheck:
Install background guard
Install scan via context menu

Please read this tutorial on Spybot S&D before using it. Spybot can do SERIOUS damage, if not used properly.

Helpful Tutorials:
Using Ad-Aware SE
Using SpywareBlaster
Using SpywareGuard
Using Ewido

If the above doesn't help rid you of the problem, then:

Read How to post a HijackThis Log.
Please read, and follow, all directions carefully.

Then, run a log, and post it in the HijackThis forum, at this link. Do not, fix anything, yet.

Thanks for the help. I downloaded Ad-Aware SE and Spybot S&D, and ran scans on both. Ad-Aware gave me 6 spyware and Spybot S&D gave me 3. After clearing these out of my system I still recieve the same error message. I then downloaded HijackThis, but when I unzip it I get a notice from McAfee saying that it has detected a virus, and I am not able to open hijack this. If I scan the HijackThis folder with McAfee it tells me there is a worm in it. Is this normal? Thanks for the help

I've also found that my sound isn't working. I tried running a game on the computer and I got a notice before it started saying that my sound card was missing or disabled, and it asked if I wanted to continue without sound. Anybody know what could cause this? Thank you for the help

Hi there, this should get rid of the error.

Go to start > run and copy and paste next line in the field:

regedit /a C:\backupkey.reg HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RPCKDM

Then open notepad and and copy and paste next bold in it:
(don't forget to copy and paste REGEDIT4)



Save this as "fix.reg" Choose to save as *all files and place it on your desktop.

It should look like this: Posted Image

Doubleclick on it and when it asks you if you want to merge the contents to the registry, click yes/ok.

Reboot and open your Internet Explorer.
Post a new hijackthislog in your next post.

Ok, I did this, but it did not work the way you described. Is something suppose to happen when I copy and paste the first line into Run? Nothing happens. When I save that notepad as "All files", it shows up with the icon of a file with no program to run it, and when I double click on it, it asks me what program I want to run it with. Thanks for the help
