Hot News about Trojan Virus

Trojan horses are the huge security threat. A Trojan is a program that enters your computer undetected, giving the attacker who planted the Trojan unrestricted access to the data stored on your computer. Trojans can transmit credit card information and other confidential data in the background. Trojans are often not caught by virus scanning engines, because these are focused on viruses, not Trojans. Catching such threats would require the use of a Trojan scanner (a.k.a Trojan cleaner, Trojan remover, anti-Trojan).

How to check/set your IE settings

To download and run the EventLogScan ActiveX control, your Internet security settings must allow you to download and run signed ActiveX controls, or at least prompt you to do this. WindowSecurity.com has gone to great lengths to ensure that this software is safe.

By default, the Internet security settings in Internet Explorer are set to Medium which allow downloading and running of signed ActiveX controls. However, if you have changed your Internet Explorer settings to high, or disabled prompting of ActiveX downloads, then you have to either set your security back to Medium by clicking on "Default level" or change the custom level to "Download and run signed ActiveX controls".



Check if your security settings are set to Medium

Resetting the Internet Security settings to default level

* Go to the Security page of the Internet options dialog (as shown in the screen shot above).
* Click on the "Default Level" button. You will be able to see that the slider has re-appeared. Ensure that the slider is set on the Medium secure levels or lower.
* Click on OK to confirm the new security settings for that zone.

Manually set your Internet Explorer security settings to allow signed ActiveX controls

To manually configure your Internet Explorer security settings to allow you to download and run signed ActiveX controls follow this procedure:

* Open the Internet options of your internet explorer browser (Start > Settings > Control Panel > Internet Options)
* Click on the Security tab
* Click on "Custom level..."
* Set the settings as indicated in the screenshot below
* Click on OK to temporarily set your custom Internet Explorer security settings.
* Click on OK to confirm the new security settings for that zone




WARNING: If you have changed any of your security settings in order to run this test, we recommend that, after running the test, you set them back to the way they were before.

How to a Remove Trojan Horse in my PC

Are you looking for, how to remove Trojan virus, the best place to start, of course, is with the company that made your anti-virus software. Most of the anti virus software companies are quickly respond to threats, and they often will have a virus removal tool posted at their web site within hours of an infection.

There are many anti virus software companies out there, and computer owners certainly have no shortage of choices when it comes time to protect their valuable equipment from harm. It has never been more important to protect our computers and the valuable data they contain. Computer owners know how important it is to run strong anti virus protection on their PC, and to keep that anti virus software up to date. Sometimes despite all our best intentions, however, we find ourselves asking how to get rid of a Trojan virus. No anti virus protection software is perfect, and it is always possible for a malicious program to slip through the radar. Dealing with a Trojan horse program is not always easy, and the cleanup methods will vary from case to case.

If no such trojan horse virus removal tool or instructions are available at your anti virus company, it is always a good idea to look at the web sites of other companies. Often one company will have a solution or information on how to get rid of a Trojan virus before the others have picked up on it. Visiting the web sites of the leading anti virus software manufacturers, including Symantec, McAfee, Computer Associates and Norton, is a good idea. Chances are one of these companies will have posted information about the infection.

After you have found out how to get rid of a Trojan horse virus, it is a good idea to review the steps carefully and to verify that each step has completed properly. In the case of a special virus removal program, the program will likely go through each step automatically. If instead you are working from a set of written instructions it is a good idea to verify each step as you go to make sure you do not miss an important step along the way.

After you have reviewed how to get rid of a Trojan virus and taken the steps to do it, be sure to scan the computer again using your anti virus software program. If the anti virus software finds no infection, the next step should be to reboot the PC and run the scan a second time. Some viruses, especially Trojan horse programs, hide out in the registry and activate each time the computer is restarted. It is important to make sure that the infection is truly gone, and the best way to do that is to restart the computer and run a thorough virus scan.

Steps to Remove a Virus from the System

Step 1
Install any one Anti-virus Software in your System.

* Symantec Norton anti-virus
* AVG anti-virus
* McAfee
* Microsoft Anti-virus

The anti-virus software should be updated regularly to retain its effectiveness. Then only it will delete new Virus Programs.

Before installing the antivirus, close all open applications and terminate any suspicious processes using Task Manager. Sometimes, you may need to boot into safe mode or safe mode with command prompt to delete suspicious programs and references to them in the Windows Registry (run regedit from the command prompt to open the registry editor).

Removing the virus beforehand might be necessary, as some viruses will not allow an anti-virus to operate. However, if you are not successful, you may still continue with the installation.

Step 2
Scan the System to Identify and Locate the Virus

Usually, the anti-virus will run automatically when the system reboots after the installation.

You may want to run a quick system scan to locate the virus.

Step 3
Troubleshooting the Virus Infected Areas

After the antivirus identifies the infected areas, the next step is to rectify those areas.

Methods of Eliminating Viruses

Generally, the antivirus adopts one of two methods to eliminate the virus:

* Removing the virus – When the virus can be easily identified and can be removed without affecting other files, then the antivirus removes it from the host place.

* Quarantine – This is done when the virus cannot be easily identified removed from the file and the removal of virus means the removal of the complete file. In this method, although the virus is not eliminated, it is rendered inactive by moving the file into "quarantine" and renaming it.

Step 4
Perform a Full System Scan

Even after the virus is removed from the system, the next step is to scan the whole system to ensure that no infected files remain.
