Please check you shared folder, if it has filled with files of the most popular games all in the 10.3KB --90.6KB file size, than you most likely have a virus called W32.KWBOT.WORM. This has a key logger, and allows the virus sender to enter your system at will, see everything you typed, see all of your passwords, and full control over your system. Please get an antivirus program if you do not have one [check local office stores as they are free every other week with a rebate]. Visit an antivirus software site for a removal tool. Change your passwords and be cautious when downloading exe files. Some common sense will tell you that "Macro Media Dream Weaver Full Working Plus Serial.exe" cannot possible be a file that is 33.3KB. Also browse host before downloading and ungroup their files. If you see 100 files all with different names, but the same small size, then find another host. If they have chat active, tell them they are infected. As peer to peer becomes an uncontrolled security risk, more ISP's will have an excuse to block traffic.
