Trojans are one of the most common and most destructive forces on the internet, and getting rid of Trojans in Windows 7 can be an annoying task. While the best way to keep your computer virus-free is to keep it from getting a Trojan in the first place, at some point or another all of us have to deal with these problems. Here are basics for getting rid of Trojans in Windows 7.
What is a Trojan and how does it Work?
A Trojan is an especially malicious form of virus that gets into your system and wreaks havoc from within. A big reason why a Trojan is so good at doing damage is the fact that they infiltrate your system looking like a normal, innocuous file (thus the name Trojan after the Trojan Horse). Here are some of the most common types of damage a Trojan will do to your system.
Delete either random files or specific types of files.
Steal your passwords for all of your online programs and websites, sending them to the attacker.
Steal information like credit card numbers and the like.
Steal personal information including pictures, documents and conversations.
Make your computer unusable due to slow down or similar issues.
Getting Rid of Trojans in Windows 7
Now, as previously mentioned the easiest way to get rid of Trojans is to never get them in the first place. Being very careful about what programs you run on your computer and what files you download (especially from unknown sources) is the best way to keep yourself from getting these malicious bits of code. Still, when you do eventually get one there are some great actions you can take to remove them from your system.
First, you want to do any spyware scanning or virus removal from Windows 7’s “Safe Mode.” To enter into this mode, restart your computer and hold or tap F8, and then choose to boot your system in Safe Mode.
From Safe Mode you’re going to want to run a scan of your system with an Anti-Virus or Anti-Spyware program. Make sure that this program is recently updated. Some Trojans will implement protocols that will keep your Antivirus or Antispyware from updating, so manually downloading the newest version is a good option.
Run a scan and delete any files it finds. Often it’s helpful to set your program to run again the next time your system boots and then to immediately restart your computer.
The Two Faces of Anti Spyware Programs
While it’s important to run scans of your system regularly with Anti-Spyware programs, it’s also important to run them in the background so you don’t have to worry too much about getting rid of Trojans in Windows 7. Most programs will offer you an option that effectively shields you from attacks in real time, and doing so is an effective complement to manually getting rid of Trojans in Windows 7 with regular supervised scans.
