So there is this website called grooveshark that shares music, so I went on to listen to some, but then I got a Trojan virus with the the name of Security Tool. The virus had caused a fake security program to pop up on the computer and kept creating pop-ups claiming that fake viruses were attacking my computer. Me and my dad managed to delete it via the Recycling Bin and promptly emptied it, so we think that got rid of it, but I want to know if anyone had this virus put on their computer before? And if this particular virus, the Security Tool, does any actual harm to the computer.
