Update: Kudos to Samsung for hitting this head-on. An hour after we inquired for comment, a company spokesperson tossed over this official quote: "Samsung takes Mr. Hassan's claims very seriously. After learning of the original post this morning on NetworkWorld.com, we launched an internal investigation into this issue. We will provide further information as soon as it is available."
Update 2: Samsung's official Korean language blog, Samsung Tomorrow, has a posted an update calling the findings false. According to Samsung, the confusion arose when the VIPRE security software mistakenly identified Microsoft's Slovene language folder ("SL") as Starlogger, which Sammy was able to recreate from an empty c:\windows\SL folder (see image above). So yeah, move along, it's much ado about nothing -- the R525 and R540 laptops are perfectly safe.
Update 3: Even GFI Software has stepped up and confirmed the good news; furthermore, it'll be changing the way it structures things so as not to set off any more false-positives.
