avg found numerous viruses from files within your archive. ( most of your exe's & dlls contain some form of viruses, too many to post them all )

7z.dll, arc.exe, compressor_chooser, ALL have viruses. Cant even upload to virus total, blocks them from uploading.
7z.dll & arc.exe can be replaced from other sources but fix the issue with compressor_chooser or
change it to a batch file so can be run manually.
