Hi, 1. Default apps: .pdf: I want to open pdfs in my sandbox using PDFXCView. I've assigned it under file association outside sandboxie, but there is no entry on Default Programs to add it. In Sandboxie, there is no way to add PDFXCview in All Applications settings. But even if I add Adobe reader to a sandbox, pdfs still always load an unregistered version of Foxit Phantom Reader (which asks me to re-enter serial number), even though I've disabled Phantom as default pdf reader from within Phantom's settings outside Sandboxie. .zip: I want to open zip files within sandbox using 7zip, but even though I've seen 7zip as enabled in sandbox's applications with two dashes (--), every time I open zip files within sandbox, I see error 'cannot open the files as archive'. How can I resolve this? 2. AV & AntiMalware Scans: What's the safest way to run scans on files downloaded into sandbox? Should I Explore Contents and run unsandboxed scan apps within sandboxed files? Or should I try to run Scan apps as sandboxed on files within same sandbox?
