Need Help!

Hey guys just became a new user to Avast cause my computer recently got infected with something. Any help that you guys could provide would be greatly appreciated. On to the problem.
It started with the fact that when I turned on my computer the other day an AirGCFG.exe error popped up. I thought that it was weird so I exited out and got ready to look on the internet to see what popped up. That didn’t work because My computer basically froze up, I couldnt click on anything but I could move my mouse and this blackish box popped up in the lower right corner. I shut down my compter and the only way I am able to access the internet is if I dont exit out that error reading. After my friend recomended Avast I ran it and it ran the search through my computer after a restart finding 2 trojan Win 32 I believe they were called. I am running another scan currently as even after that the same problem occurred.
Any help would be wonderful and I hope I dont have to scrap this computer. The AirGCFG.exe error reads: the procedure entry point apsSearchInterface could not be located in the dynamic link lybrary wlanapi.dll

BTW I am also getting a K:/autorun.inf VBS:Malware-gen reading every 10 sec regardless if I choose to delete the virus or not

Maybe this helps…

[*] Download Flash Drive Disinfector and save it to your desktop.
[*] Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
[*] The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.
[*] Wait until it has finished scanning and then exit the program.
[*] Reboot your computer when done.
[*] Note: Flash Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don’t delete this folder… it will help protect your drives from future infection.

I did this and my task bar/ start up bar on the bottom just disappeared

Click ctrl+alt+del and go to file > run and then write down Explorer.exe then click enter.
The bar will be shown again. Or you can just boot the computer.

thanks I just rebooted my computer… Now there is a error popping up from Windows saying Data Execution Provention
To help protect your computer, windows has closed this program. windows explorer.

Also problem has not been fixed… All errors continue… Is my computer done for?

any ideas

Are you using Windows XP/Vista?
Can you schedule a boot-time scanning?
Start avast! > Right click the skin > Schedule a boot-time scanning.
Select for scanning archives.
Boot.
If infected files are found, it’s safer to send them to Chest instead of deleting them.
This way you can further analysis them.

I am using Windows XP.
I did the boot time scan and nothing was found. hopefully everything works fine… thanks for everything I’ll post another message if anything goes wrong
