Windows cannot access the specified device, path, or file...

Gentlemen, I am in desperate need of your expertise. I have been using Avast and Spybot Search and Destroy to keep my computer protected, as well as using CCleaner and Iobit Advanced System Care to keep things streamlined and running smoothly. Avast recently popped up a warning about Braviax.exe, so I tried to do a manual virus scan (as I do once or twice a week) and I got an error message stating "Windows cannot access the specified device, path or file. You may not have the appropriate permission setting to access this file." Confused, I did some research on the message but found nothing relavant to my situation. I tried downloading and installing AntiVir, then clicked on it to run. It started to run, then disappeared after about 5 seconds. I clicked on it again to bring it back up, and Windows gave me the same permissions error. I have now done everything requested of me in the READ AND RUN ME FIRST post, all to no avail.

I could not download RootRepeal because the page had exceeded bandwidth.

I tried to install superantispyware, but i received the message "error 1321:windows installer has insufficient privileges to modify this fil: C:\Program Files\SuperAntispyware\SuperAntispyware.exe"
However, the icon for the program was on my desktop, so I tried to run it, only to receive the original permissions message.

I installed MalwareBytes and tried to run it, but after five seconds it disappeared and I got the permissions message when I tried again.

I installed ComboFix and when i ran it, it came up with the message "combofix has detected the presence of rootkit activity and needs to reboot the machine". After it reboots nothing happens, if I run it again the same thing happens.

Every virus program that I have been able to find has run once for about 5 seconds, or until it tries to do a virus scan, then shuts down. After that I get the permissions message. I would appreciate any advice you guys can give me. I am running Windows XP SP2.

 

Anybody? Anything?

 

Thank you for your help, first and foremost. I'm sorry I missed the rootrepeal link, I was able to run it and it somehow unlocked all the other programs, so I followed your instructions as well as the instructions in the run and read me! sticky. Everything seems to be working now (as far as I can tell, the programs that I first noticed the problems with all seem to be fine now). I have attached the logs you requested, although I did not run the SAS online scan as the one I downloaded worked.

Just out of curiosity, I have been using Avast for my viruses, Spybot Search and Destroy for the malware, and CCleaner and IObit Advanced Systemcare 3 for the maintenance. Avast runs in the background all the time, and I do manual scans with Avast and Spybot at least once a week. How did I get this infection?? Are these programs crap, or was I just really unlucky? Is there something else I should be using instead? Thank you once again for all your advice, I love this site.

 

here are the other two logs you requested.
