Malware deactivated my ESET NOD32 and Malwarebytes doesn't run

Hi everyone!

I am in deep despair! I think my laptop might have been infected by a malware. I and my buddies were at this coffee shop and we were using the free Wifi. My ESET NOD32 initially detected the virus/es (the one i remember was peerfrag.exe) so I was a bit appeased and I was a bit confident because I update my virus database daily. The situation of my friend's laptop (OS Win Vista) is worse; it actually refused to run anymore and just displayed this message upon startup saying windows is looking for errors (something like that) which displays several corrupted files after scanning.

NOTE: I TRIED THE INSTRUCTIONS IN READ AND RUN ME FIRST BUT WAS NOT ABLE TO PROCEED BECAUSE THE SITE WHERE I'M SUPPOSED TO DOWNLOAD CC CLEANER DOES NOT LOAD. I THINK IT'S BLOCKED TOO (LIKE ANY OTHER WEBSITES OF ANTIVIRUS SOFTWARE)

So okay. What is actually happening to my computer:
*BLOCKED ANTIVIRUS SOFTWARE WEBSITES
*ESET NOD32 DOESN'T WORK. THE MESSAGE "error communicating with kernel" IS DISPLAYED
*MALWAREBYTES ANTIMALWARE DOESN'T WORK TOO (SO I UNINSTALLED IT.)
*FOUND IN THE TASK MANAGER: A9a4d1.exe (This just appeared from nowhere). I actually end this process upon startup. It is not persistent.
*SOMETHING WANTS TO OPEN INTERNET EXPLORER. THE TAB: "This page is unavailable offline" appears persistently.

I'd be happy to proceed with the "READ AND RUN ME FIRST" BUT I HAVE NO IDEA HOW TO PROCEED WITH DOWNLOADING CC CLEANER. I think it might be possible that someone just provide the download links so I could use a downloading software (I have DAP).

Thanks! Gracias! Merci! Salamat!

 

BTW!

I USE:
OS: Windows XP 32 SP3
Browser: Opera
