Trojan Removal

A Trojan or a Trojan Horse Virus is a program that a computer user downloads thinking it is one thing (such as an mp3, video or some program) but is actually something else entirely, living up to its namesake from the ancient Greek days. Once executed, a Trojan usually performs some useful function, but is commonly used to unknowingly allow unauthorized access to the user’s computer system at the same time.

Hackers and Cyber-Criminals use Trojans to gain remote access to a user’s computer so they can use your computer to perform just about anything under the sun, usually something malicious that they can profit with financially.  Some examples of this are:

• Data or Identity Theft
• Keystroke Logging (keyloggers)
• Downloading or Uploading Files
• Viewing the User’s Screen
• Crashing the User’s System

Depending on your security software … or lack of, a Trojan infection can go undetected for several days to several weeks, and even indefinitely if you have expired, corrupted or no protection at all. But there are usually telltale signs that should make you suspicious of an infection if your computer has become very slow for no good reason, if your internet browser home page was changed, or it keeps automatically redirecting to some other webpage, otherwise known as a hijacked browser. If you are experiencing any or all of these symptoms, your computer is probably infected with a virus.

Sometimes they give themselves away by using misspelled versions of legitimate file names, or even random names that stick out like a sore thumb to an experienced PC Technician.

Aside from a Trojan infections, most computers are usually infested with a variety of other forms of Malware such as Spyware, Adware, and Browser Helper Objects (BHOs), and sometimes Worms, Viruses, and Rootkits. But the most common type of Trojan infection these days are the Fake Alerts Programs, such as a Fake Antivirus Program.

Typical Symptoms of a Trojan Infection

• Slow computer performance
• Windows randomly freezes
• Hijacked Internet Browser
• Randomly appearing popup windows, especially while surfing the internet
• Fake Alerts, when some program alerts you that your system has numerous Windows and registry errors or a variety of infections, and even redirects you to a website that prompts you to purchase their software to remove the infections.

Can I Fix It Myself?

The solution varies on a case-by-case basis depending on your operating system, severity of the infection, what security software you already have installed, whether it is updated or not, if the internet still works, and on-and-on. If you have several of these things going for you in your favor, you may be able to try and fix it yourself, otherwise you might want to save the trouble and chance of making it worse by having it professionally repaired.

From my experience, I can tell you that most people will choose the least expensive approach, whether or not they have any training or tools to do the job. They figure that they can Google for some freeware program and fix it themselves for free. Just beware that there are plenty of malicious links that may show up in your search results that may promote products claiming it can fix your problem, but in reality may just infect your computer further.

Also, many of the techniques PC Technicians use to clean computers involve much more than just running scans with some program. Many of these techniques require an advanced knowledge of Windows and its built-in utilities such as the Registry.

Rather than trying to repair your system with one of the free basic antivirus programs out there, I suggest you at least download and install a free trial version of a top-tier antivirus program such as an ESET Nod32 or Smart Security. That will at least buy you some time before you decide if you want to ultimately go with the freeware method. Then I would follow-up with a good antispyware program such as SUPERAntiSpyware or MalwareBytes.
