Thank you for the help.
The major problem "the page can't display" is already solved.
I ckecked "2:病毒木马注入Explorer.exe进程中,导致运行IE慢。杀毒,或者重新安装系统", and I didn't
find any virus on my computer. Although, I am at US and I have T1 internet speed, but the access
speed to your website is still kind the slower than before. Anyway, thanks again. I like YYcaF very
much.
