Is there an PDF checker(s?) that runs on XP? I've seen some command-line unix tools that will give some indications of malicious PDFs... but I'm not sure what I should be looking for in utilities to find something gui-fied, that I can just drop a PDF on and find out if it's going to zip-bomb, or auto-launch (if I'm using FoxIt, I've heard Adobe *might* be on-top of *some* of those security holes), or whatever else... I've been downloading PDFs rather indiscriminately, and I'd really like to check 'em (are they working? how many pages? encrypted? have auto-launch commands? etc., etc., etc.) before launching. I'm not sure that my anti-virus and anti-malware will catch 'em if they want to **** with stuff. Luckily, I've avoided the iLivid install traps... so far. But that's just because I've been really squirrelly about being willing to launch an exe to get at a PDF.
