Infected With Trojan Horse Agent4.AQLZ – How to Remove?

The Trojan Horse Agent4.AQLZ virus is a malicious attack that computer hackers have designed with one goal in mind, and that is to gain access to as many computers as possible and steal personal and financial information to be used to commit fraud and sell on the black market to other cyber criminal groups. Like Trojan Horse PSW.OnlineGames4.ALGT, this is a very dangerous virus, and a perfect example of why every computer should be equipped with updated anti-virus software that is set to run every time the computer is turned on. While some users may consider that extreme, it is important to make sure that the computers are protected.

Once the Trojan Horse Agent4.AQLZ virus is installed on the computer it begins to alter the system settings. It disables some programs while burying itself deeper into the root directory, making it harder to find. It then has the ability to grant access remotely to the hackers and allow them to search through all of the files and directories on the computer. The look for anything that they can use to commit identity theft and bank theft. Think about all of the information that is stored on a computer. Personal data and financial data. A hacker could easily find contact information and then if the user happened to have tax return documents stored on the PC they could then have the social security number and other personal identification information, which would be all they needed to open up credit cards in the users name and commit other financial fraud.

While the hackers are searching through the computer the Trojan Horse Agent4.AQLZ virus will begin to attract and install additional Trojan’s and Worms. One of the biggest indicators that something is wrong is the slowing down of regular options on the computer, and this is due to the available memory on the computer being used up by these additional viruses. If nothing is done these malicious attacks will use up all of the system memory and it can lead to a complete computer crash. If that happens there is a chance that all of the data and files will be lost unless is it backed up on an outside platform. Hence, you must get it off of your computer ASAP.

  • Some programs will not even open and warning messages will be displayed instead, warning the user that they are not available. As the Trojan does more damage the warning and error messages will become much more frequent.

This will destroy all of the data and files on the computer. There is a very good chance that the hard drive will not be able to be recovered after. This is why it is so important to keep a backup on a cloud server or on an external hard drive to make sure that you never lose valuable information and files in the event of an attack.
