Trojan Horse Downloader.perfiler.a

My son downloaded the latest update from AVG and rebooted his PC as requested. The result was every time the PC is booted, it gets to loading the Icons in System Tray and freezes at the AVG Icon. He is then informed Trojan Horse Downloader.perfiler.a Found in file
c:Windows\system\MSA64chk.dll.
Following the instructions to clear this problem, the PC Freezes. He has tried a System Restore but it resulted in the same problem.
He is currently unable to operate his computer at all.
Windows ME is the OS.
All offers of help gratefully accepted. Hoping that a format and reinstall will not be required.
