Okay i am on Microsoft XP And this may not be the most deadly one but the most annoying one Virus/spyware/unkwon is called : winReanimator This is a fake antivirus program that just doens't die Annoying popup and icon in the taskbar every few minutes. There is no way to take it out unless you visit the registry Side Effects: Annoying adult ads, firefox popups, icon is taskbar which you can't take out, and REALLY ANNOYING redirects everytime your browsing through the internet. Example: your searching through ebay or google, you click a link and you get automatically redirected to a site you don't want. The most common one is called "search explorer" Currently my laptop is infected with this virus from a bad download I made fomr bittorent. I have abandoned my laptop and I am using my PC right now. If anyone has any idea how to get rid of it for windows xp please let me know I am sure at least 1 million of our population has their systems infected. As I have googled how to disinfect it and there were thousands out there asking the same question. I posted this as this related to Microsoft, if you think this is the wrong place to post please let me know so i can ask the mods to take it out. Thank You -james
