Yes I do have ideas :D! Download Microsoft Anti-spyware! I have a feeling I'll be saying this a lot. If you don't like microsoft get Spybot and Adaware. They work well in conjunction, but MS Anti-Spyware owns them :D. It's not your broadband connection, it wasn't from deleting your cookies or cache either. I suppose I could be incorrect in that regard, but I doubt it. Deleting your cookies is generally a good idea (gets rid of tracking cookies and such) most antispyware programs will do that for you though. Anyway you also want to get some virus protection and a firewall. Zone Alarm has a nice, free firewall. You can also find some online virus scanners such as housecall.antivirus.com. You must be protected on all fronts!
1)Get Microsoft Anti-spyware
2)Update Microsoft Anti-spyware
3)Run it
4)Get Zone Alarm Firewall
5)Get some anti-virus software
6)Go to housecall.antivirus.com
7)Run a virus scan or virus/spyware scan.
8)Don't forget to update Firefox (if you forgot)
9)Be Happy
Hope this helps
p.s. Sweet Clementine bah! bah! bah! Thats a song... nevermind *runs away*
