Remove mention of anti-virus scan

Index page mentioned binary assets were being
scanned for viruses - this is not being practiced
consistently, and should not be mentioned. Removing
for now, and will eventually be replaced with
legal disclaimer indicating downloader is responsible
for determining safety and suitability of all assets.
