This is true. I've recieved several flakey inclusions in zip folders that were honestly not known to the sender. It's an easy, 'though (luckily) not common mistake. to make. I"ve seen it more often when a MAC user uses a WIN9X machine than not. Until I setup filtering to block EXE's & ZIPs in my newsreader, I was getting 1 or 2 flaky files imbedded in newsgroup postings a month. Usually a WIN9X readonly/hidden/system file included when someone ZIPS something from their desktop. I use Ad-Aware 5.5 to keep on top of the most common Spyware, & visit Steve Gibson'e GRC site to keep abreast of the latest in sneaky datamining techniques & privacy assaults. I'd be pretty certain this is nothing suspect.
