Does the latest Adobe Acrobat Reader software have spyware? I've read that it does, others claim it's a feature. I'm not sure if this is a rumor or not. If 5.x does have spyware, anyone know where I can download the 4.0 installer (US English version)?
Only "spyware-ish" feature I've noted is that it periodically calls home and checks for upgrades, which most software does nowadays. If you're unsure of some software, install a firewall app, it should tell you of anything odd going on (you'll still get the fun of cleaning up after any spyware should you happen to install some, though).
