Well, specifically bad:( You obligation to anti-adware scan and spyware scan:( Too bad, I can't move about to your house and help you to find the pop-up virus:( So far, Norton Antivirus can't afford much help!:(

Software for scan that I may recommend:
AVG Free edition
Lavasoft Ad-Aware SE Personal
Spybot

You can also try the online virus scan from http://www.pandasoftware.com/
This online scan will give you the result of possible virus, but you call for to delete the virus by your own. You need to entry down the location of the virus and you need to delete the virus from the Command Prompt mode. You necessitate to enter the Command Prompt when you first start your laptop.

By the way, what do you tight by not able to bring back wireless Internet? Do you mean that you can't seize wireless Internet connection? If you obligation to use the wireless way connecting to Internet, your laptop obligation to have a wireless delivery device (some of them call this device as Wi-Fi card). The device can be an internal or external device. It is better for the wireless reception device to be internally attached to your laptop:) In that way, you can own a faster connection. For external wireless reception device, you need to connec the device through USB ports. That will impart you a very slow verbs rate:( Moreover, you need a wireless router if you entail to use the wireless function. Anyway, the wireless connection should pass you an increase in the nouns speed:) It is always true that nouns through wireless is the fastet way of nouns:)
It sounds like some type of virus or spyware get into your system. Run your antivirus program (make sure it has the particularly latest definitions) and run a spyware removal tool such as spybot turn out and destroy or adaware, (once again, the switch is to make sure it's updated). Afterwards, try uninstalling and reinstalling the drivers for your wireless device. If you use a pcmcia card device for your wireless, you may want to try eject it and re-inserting it as well to see if that help.

If you are having issues near the wireless not obtaining an IP address from the router, sometimes this help...

start-run-type "cmd" (no quotes) to open a DOS-like glass
issue the following command (no quotes):
"ipconfig /release /renew"
reboot and try again

Hope this is helpful!
