Sunshine,
It is my guess that your computer has spyware and adware. They become the "magnet" to draw in all the unwanted connection attempts.
In addition, you could be infected with a trojan/worm.
Do you have any antispyware installed such as
SpywareBlaster and
SpywareGuard?
Spybot Search and Destroy, and Adaware are manual antispyware scanners you can download.
All of the programs above are freeware:
www.snapfiles.comAt this point, I would install a manual scanner such as
Adaware from
www.lavasoft.de and run it to clean up the computer.
Also run a full Avast virus scan with it set to Thorough and include Archives.
In addition, consider installing
Hijack This. You will find the link on Eddy's signature at the bottom of his posts. It is an excellent tool. If you do decide to use it, there is both a downloadable and an online
Hijack This Analyzer that goes with it to determine the condition of your system. The online HJT Analyzer is easier to use and understand.
I hope this information was not too much for you. If you need further clarification, please ask me.
