There are 4 download mirrors. The first two contain a zip file that after installation has an exe named aimp_classic_2.0.7.1_beta.exe or so. The 3rd and 4th download links offer a file named aimp_full.exe.

So now I really wonder what's the difference. Anyway, the first two links contain a file with a VIRUS INSIDE. Double-check with virustotal.com where you can upload the file and have it checked by several virus scanners. Strangewise the other two links do not contain a trojan - but also they are named totally different and differ also in size from the first two trojan-infected files.

It seems those Russan developers spread trojan software for whatever reasons. On their webpage itself you can also only download a virus-infected version.

So DO NOT DOWNLOAD THIS !!!
