Say Neigh to the Trojan Horse!

The Trojan horse type of virus and malware gets its name from the classical tale of the Trojan horse. In the story, a horse is sent to the city of Troy. The horse was a cover rather than a gift; it contained a number of soldiers planning to destroy Troy.

That is why calling this a Trojan horse virus is particularly appropriate. Initially, a lot of them seem perfectly normal. However, truly they are malicious and enable hackers to enter a person's computer and do damage.

You could get a virus by downloading a simple screensaver. When run, the screensaver runs hidden programs, scripts, commands, and functions that the user doesn't know about. These programs may be able to usurp your virus protector and get into your computer.

Deleting Trojans can be a problem because they come in so many forms. However, there are a lot of programs available. In fact, since Trojans are viruses, your virus scanner should pick them up.

The first step is letting your virus protector scan your computer. You can delete any files you know to be corrupted. Since your temporary Internet files can hide Trojan viruses, the next step is deleting those.

The next step is restarting and scanning your computer. Any Trojans on your computer will be deleted or quarantined by your virus scanner.

Booting up from a CD and viewing any files before they are loaded can help if you still have problems. They like to hide in registry files and processes. It can be hard to find the files that don't belong in your computer, which is why your virus protector comes in handy.

The problem with Trojans, unlike adware or spyware (sometimes Trojans hide or work in accordance with these things) is that they can come in any file. Take our example for instance, a screen saver file, who'd have thought it?

A good measure to take is to scan every file you download with antivirus software to make sure it's safe to open before you do. Most times it'll be okay, but some times it won't be, when these times occur you'll be happy you spent money on anti-virus software.

If, after you've done all you think you can, the problem persists, then it's time to consult a professional. A computer tech will be able to purge your computer. Of course, expunging your computer's files yourself is also an option. If you have the CD for your operating system, you can reformat your computer. This is necessary because reformatting will delete your OS as well.

This might seem like a huge step, but it's always possible to reinstall your programs afterward.

However, you still need to take care of your computer so the Trojans won't come back!

Norton Antivirus 2007: an Upgrade Finally Worth the Wait

The Norton brand is probably the most synonymous brand when it comes to virus protection software. Norton Antivirus has been in existence since 1990, and since then a growing number of people have come to rely on the Norton name to protect their computers from virus attacks. In fact, Norton Antivirus is considered the most widely used antivirus software in the world today.

Over the years, Norton Antivirus has constantly underwent upgrades as a means of trying to improve on its ability to detect a growing number of viruses that are being spread. Additionally, each generation of the software incorporates several new features and services as a way of making it more effective in its task of detecting and eliminating (or quarantining) viruses as well as turning it into a more robust application. For example, in recent years, Norton Antivirus has begun to incorporate the detection not only of viruses but also of Trojan horses, spyware and worms as a direct response to the growing proliferation of these potentially harmful pieces of malware.

With the release of Norton Antivirus 2007, users should expect to see another set of new features that will help it remain the top of its class when it comes to virus protection. One of the biggest changes in the 2007 version over the previous 2006 version is the decision of the Norton Antivirus team to rewrite much of the code for the application. The result of this overhaul is a faster and lighter version of the antivirus software. Rewriting the code also meant that the interface was streamlined as well. Unlike the previous version, where each task appeared in a separate desktop window, the 2007 version wisely uses tabs inside just one window, which makes it much easier to manage.

Under the hood, Norton Antivirus also benefited from the code rewrite. For instance, the virus scan and the spyware scan now run simultaneously, which drastically cuts down on scanning time. Norton Antivirus 2007 also incorporates many of the functions of Norton Personal Firewall, which means the application can now also double as a “light” firewall.

Another very important feature of the new version of Norton Antivirus is the incorporation of enterprise level anti rootkit functions. This powerful level of protection against rootkits is well worth the price of the software especially with the growing prevalence of rootkit based attacks on computers. Overall Norton Antivirus 2007 is still arguably the best antivirus protection one can get, and the new version was definitely worth the wait unlike previous versions which disappointed.

Xp Antivirus: Dreadly Security Software Removal

The year 2008 definitely showed its benevolence for Internet scammers: they found a way to get paid for their illegal activity.
And that way includes wild distribution of fake security software via aggressive spamming on forums and blogs.
One example of such software is a notoriously known XP antivirus, also called Windows XP antivirus 2008. It is a classic rogue software that behaves quite differently from what it claims to do. So, instead of scanning for viruses and removing them, it ruins the system security by opening wide breaches, then installs Trojans and acts like any other spyware – but that's not all. XP antivirus scares the user into buying the full version of it! Of course, the paid version doesn't get any milder on the computer, but it reaches the goal – its creators get money for their evil work.
So how do you tell if your PC has been infected with XP anti virus?
There are signs that cannot go unnoticed:

Windows-like balloons inform about malware detected in the system;
A corrupt Windows security center recommends downloading antivirus software;
Pop-ups scare the user with all kinds of messages urging to get the protection NOW;
While visiting websites you may see annoying pop-ups offering free online scan.

A sad fact about this rogue software is that it stays unnoticed by antivirus programs. To get rid of XP antivirus, you can follow several simple manual steps:

1. unregister DLL-files related to XP antivirus or modified by it;
2. end malicious processes in the Task Manager;
3. remove relevant entries from the Windows registry;
4. locate and delete program files installed by the software.

There's nothing really complicated with the manual removal procedure; any intermediate PC user can do that.
However, if you don’t feel like playing with the system and registry (which is always risky), there are tools that can do the removal process for you for free.
Visit the hubpage in my resource box to find detailed instructions on how to get rid of XP antivirus.

Virustrigger is not an Antivirus!

It all starts when the Vundo or Zlob Trojan makes its way onto your computer. The Trojan is set to run on login and can get on your computer from you opening spam or accepting what you think is a video codec. After that your computer is flooded with pop-ups telling you that your computer is infected and only VirusTrigger will save your computer.
 
When you click on the pop-ups and go to VirusTrigger2009.com or virus-trigger.com you will find a fake scan that tells you that needed Windows system files are an infection. You will then be prompted to pay either $49.95 or $79.95 for a “full version” of VirusTrigger.
 
A closer look at the website will find a fake article about achievements of the company. An even closer look will find many grammatical errors in the text and no contact information to be found. In some places the VirusTrigger product name is changed to TotalCleaner.
 
Once the money is paid and VirusTrigger is installed on your computer you will find that the pop-ups do not go away. In fact, pop-ups stating your computer is under attack will be added to the pop-ups telling you that you are infected. More advertisement pop-ups show up on your desktop. VirusTrigger is really a bundle of malware, spyware and adware. VirusTrigger will also change your browser settings and connect itself to the internet to join your computer in a spam campaign or a denial-of-service attack without your knowledge or permission. VirusTrigger will stay resident in your background, slowing your computer down.
 
If you try to remove VirusTrigger you will soon find that Add/Remove Programs does not work. In fact, removing it manually barely works, and is dangerous if you are not familiar with the registry of your operating system. This is because if you miss a single file VirusTrigger will reinstall itself, and it is hard to get all the files. We call programs that behave like this rogue anti-spyware programs.
 
Programs like VirusTrigger are also called rootkits. A rootkit is a piece of programming that digs into the root of a computer’s operating system (the registry) and takes some fundamental control of your computer. This includes changing your browser settings, connecting your computer to the internet for reasons you would not want it to connect to the internet for, and without your knowledge or permission.
 
So how do you remove VirusTrigger? If you can’t uninstall it the usual way and manually is dangerous and iffy, what do you do? A little leg work is needed on your end. You have to do some research. As you learned from VirusTrigger you can’t take a company’s word that it is legitimate. You can’t believe the articles on their site they post about themselves. You can go to websites known to give awards for exceptional programs and browse through the winners of their awards. A few places to look are Tucows, WUGNET, Soft14.com and Topshareware.com. If a program has any of these awards you have not only a legitimate program, but also a good program.
