Computer, Spyware & Virus

Most people with even just a cursory understanding of Greek mythology are familiar with the story of the Trojan Horse, the clever ploy devised by crafty Odysseus that finally ended the decade long Trojan War. The story goes that the Greeks pretended to surrender and left a peace offering of a large wooden horse, but hidden inside the wooden walls were the strongest Greek warriors waiting to ambush the city of Troy when the Trojans let their guard down. The horse was dragged through the city gates and while the Trojans slept, exhausted after celebrating what they thought was the end of the war, the Greek warriors came out of hiding and destroyed Troy once and for all.
So what does this story have to do with Trojan virus removal? Well, the way that a Trojan horse virus attacks your computer is similar to the way that the Greeks ransacked Troy many, many years ago. Crafty hackers have devised a way to infiltrate your computer without your even being aware of it. Technically, you're aware of the infiltration itself but you don't realize that it's dangerous until it's too late. It's kind of like taking candy from a stranger with questionable motives. Trojan horses usually come in the form of a harmless looking e-mail or file like music or pictures. You download or open it, and nothing seems to be amiss.
But maybe you start to notice that your computer is moving awfully slowly. Random pop-ups keep dominating your screen. In the worst case scenario, your passwords are all compromised and you've basically lost control of your computer. These are good signs that you might be infected with a Trojan horse, and some Trojan virus removal might be in order.
Often people depend on antivirus software to remove Trojan horses, which can be helpful but it's not a surefire solution. It's a good precaution, but Trojan viruses are always evolving and you can never be sure, so Trojan virus removal by antivirus software isn't guaranteed. You should constantly update your antivirus software in order to protect yourself as well as you can. The only way to get rid of a Trojan horse for sure is to clean reinstall your computer. This essentially means erasing everything on your computer, so you have to backup everything you want to keep and then reinstall it.
A clean reinstall will ensure Trojan virus removal, but it's tedious so the best way to be free of Trojan viruses is to prevent infection in the first place. Don't download anything from a source that you don't trust! And if you do, understand that there are risks and prepare to deal with the consequences.
