Trojan.Tdss.HWD keeps coming back

[Javiier]

Why does the Trojan.Tdss.HWD keeps coming back on my computer repeatedly. The Trojan.Tdss.HWD keeps coming back was detected first a month ago now and using my Kaspersky anti-virus I was able to delete it. But then again after few days I again got an alert message regarding the detection of Trojan.Tdss.HWD. Now every time I delete it and it just keeps coming back. How to permanently delete it?

Trojans are designed to hack the user's sensitive information. The Trojan.Tdss.HWD is also designed for the same purpose. The remote attacker can also gain access to the infected machine. The Trojan keeps sending back the user's sensitive data to the remote attacker. To save itself from getting deleted it makes an entry in the Windows Registry.

The Trojan.Tdss.HWD is also being recognized by Microsoft as a Severe Level Threat. This trojan is known to carry out the following actions on the infected host machine:

• Redirecting search queries.
• Cause Denial of Service Attack.
• Downloading unknown files that contain malicious programs.
• Send user data to remote hacker.
• Install Fake anti-virus.
• Corrupt System Restore Points.

It can be that the trojan has modified your Firewall settings. As the trojan might have succeeded in disabling the Windows Firewall it makes it more easier to keep coming back to your computer. So in order to restrict the trojan from coming back you would first have to check your Firewall settings. Following steps will help you to Turn On Windows Firewall on Windows 7:

• Go to the Start Menu.
• Open the Control Panel.
• Enter Windows Firewall in the search box and select Windows Firewall.
• Click on Turn Windows Firewall on or off.
• Click Turn on Windows Firewall under each network location that you want to help protect, and then click OK.

It seems that the trojan has modified the antivirus program which though might be able to detect it, it fails to remove it completely. I recommend you to use some other reliable antivirus. I am using Avast anti-virus and I suggest you also may try using the same. This anti-virus has a Boot-Scan feature that will help you to scan your computer before the operating system is loaded.
