Your virus scanner may detect the lobby as unsafe - this is a false positive and should be reported to the makers of your scanner.
All hail Little Fighter 2. It is, quite frankly the best brawler in its class that has ever been my priviledge to play. The characters are wide, and each has a specific fighting style, so it is possible to get really good with any character. Some of the special moves, however, do get a bit repetitive.
YinYin has provided a list of virus scanner report forms where you can submit the lobby for verification as a false positive.
