Problem between Avast4 GUI and CLI

I am running openSUSE 10.2 and when I was running a scan on my system Avast GUI says this:

File "/windows/C/pagefile.sys" is infected by "Win32:Adloader-AC [Trj]" virus. Version of current VPS file is 764-8, 08/12/07.
I tried to tell Avast what to do with it but no matter what I told it it errored out, so then I run avast from xterm on /windows and the CLI avast reported that /windows is virus clean. Not knowing which version of Avast is right I am running Clamav to see what it says, but shouldn't the GUI and CLI be giving the same report, considering its the same program. I will post the result of clamscan. Could I have possable stubled upon a bug in Avast?

Most probably a false positive of the Linux version.
When you run a boot time scanning with Windows, will avast detect this file as being infected?

No, according to avast, using both boot time scanner and on-demand scanner, under windows, and the Microsoft Live One Care scanner my windows boot is clean. I can tell that more than likely its a false positive, seeing as every scan I ran on my system except the Linux versions GUI came up as my system being clean. Clamav’s clamscan even came back as being clean.

please, update avast to the latest VPS file and then try to scan the file again

Same GUI picks up the Win32:Adloader-AC [Trj], using VPS version 765-1, 08/13/2007, and the CLI says that it is clean

Could the difference be in different scanner settings (“all files”, “whole files”, etc.)?

Well using the GUI I tell it to do a thorough scan including archives, and at the command line I let it do the default action which is to scan all files including archives, as far as I can tell it is the same thing.
