Troj/Bancos-BGA

Avast is not finding this trojan.  Any good way to find out if this is a false positve and if not the best way to remove the threat without purging Avast?

upload it to virustotal.com (VT) and post the link to the results.

if you want to move the file to avast! chest then do this : virus chest > user files > add files - browse for files > click email to avast! and do a manual update.

alternate method to upload to avast!: zip the file with a password and send the zipped file  to virus@avast.com with the password for the zip in the body of the email.

first of all upload the file to VT and post the link here.

edit: didn't avast give any warning saying "Win32:Rootkit-gen" ?

The program that found these issues was sophos anti-rootkit 1.5.  Avast boot scan noted cab archive corrupted which I have been told means that Avast cannot open the file and does not indicate malware.  Not the spots where the problem exists anyway.

not sure if I can capture a screenshot while doing a boot scan but will try and get it next run

These files seem to be designed so that they cannot be uploaded or copied

according to the sophos log file, it reports windows update files, possibly, which will be copied to a temporary folder while installing any update manually.

and, i think, the temporary files are ok.

can you do a scan using hijack this (get it here) and post log here: use additional options and upload log file.
