Dangerous Spamming Floods Inbox and Brings Virus To Personal Computer

I always get irritated every time I surf in the internet, because my internet connection always ran slowly and slowly specially during night time. I really hate this experience that my message will not be send, because the slow internet, and it is very annoying that I cannot retrieve the messages I typed, so I always fall in retyping them from trash, and sometimes I forgot the most important things that I must include in my messages. Other problem is that, when I am chatting in my yahoo messenger, I always got disconnected and left behind with the topic, and I can’t catch them easily, for I have to log in again and it took me long time. I am always sending messages for I thought they receive it, and in reality they never get it, so I really have to wait the time that the internet connection becomes alright.
