Unless you know for sure that your problem didn't exist earlier than 24 hours ago, you may very well NOT have removed it. If you don't know where you got it, you will most likely go to that website again and get reinfected. I suggest you Get SpyBot Search & Destroy to safely remove spyware. Best of all, it’s free. After installing it, immunize the computer against over 31,000 known pieces of spyware. Then run a full bot check and remove everything it finds using the Fix Selected Problems tab. Keep it updated and run it weekly to keep your computer free of this stuff. Then get Ad-Aware also from download.com and run it the first time doing a Full System Scan. Thereafter, run a Smart Scan daily.

Cookies are spyware, little bits of code that tell website owners who you are and how many times you surf their website. Clean the computer up at least weekly to prevent malware infections.
