Hello,
It seems that you are very frustrated. I am assuming that you are using Windows something, but as you did not specify what you are actually using, it limits what we can say about it.
Couple considerations:
1) Switch to Linux. Escape anything written for Microsoft. This is not to be taken lightly, but Linux has a lot going for it. You can use the internet. You can use your printer (unless it is something really weird!). You can type letters, and save them.
2) If you have to remain with Windows, FORMAT, re-install, and patch. Find a different web browser besides IE. Use Mozilla or Opera. Install antivirus.
3) Tell Mozilla / Firebird to block popup windows. Some sites might not work with it, but well, that is the price of protection.
4) If you are on a cable modem / DSL line, install and configure the firewall properly.
5) If you are into warez, or serial numbers, stay away from the websites that offer that information! Just as a wim, I built a Windose box and went to one of those sites, and caught something. All within 15 minutes.
6) Don't open attachments from email.
It is possible to be on the internet and not get infected / distorted. My Mac and Linux systems have been doing it for several years now. Windows people will need to be more diligent with IE, as a lot more attacks are geared for them. No operating system is perfect; to remain completely clean, unplug from the internet.
