Just clicked on a link to dropbox (from someone I know and knew what the folder should contain) and Kaspersky immediately popped up with threat alerts to a virus & worm. I even browsed the folder (pictures) and didn't notice any extra file that shouldn't be there. Kaspersky removed the file, but I'm loath to click the link again to check. I'm wondering if anyone here's had similar issues with Dropbox? Googling the issues turn up stuff that mostly deal with hackers getting your account.
