I protect my PC from any viruses. Then I could download "1 Click Spamshield". Next time, I installed this program. Once shot down my PC, perhaps BIOS was read. But my PC was hang up. The icons and start menu was be showed. But when I click the menu button, there are no pop up menu. This was not be showed. I use the OS of windows XP. I use DELL 4300c. How are you thinking about the using the 1ClickSpamShield in my PC ? How can I restart PC ? The desktop has many fooders and files. I didi not save these informations in secondary memory. Would you please about the problem solving ? HIRO yamamaybba@yahoo.co.jp 1-4-15, NishiAzabu, Minato-ku, TOKYO
