I've recently had my laptop infected by the trojan: maran.j

I've tried ad-aware, ewido online scan, bitdefender online scan, and spybot (all run in safe mode). Spybot is the only one that detects the trojan but everytime I delete it, it returns automatically on the next restart. If somebody could help me please, thanks.

See if you have these files on your computer.

Troj/Maran-J is a password stealing Trojan.

Backdoor Trojans, IRCBots and Infostealers are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans as part of an exploit to to gain unauthorized access to a computer and take control of it without your knowledge. Read the Danger: Remote Access Trojans.

If your computer was used for online banking, has credit card information or other sensitive data on it, you should immediately disconnect your computer from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay and forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breech.

Although the backdoor Trojan has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because the backdoor Trojan has been removed the computer is now secure. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat and reinstall the OS - "When should I re-format?".

In my book that is a good thing. Those are files you should have if Trojan.maran is on your computer.

Likely a "false/positive".

If you are not having any malware symptoms, I would ignore it.

Did Spybot actually identify any file on your computer as being Trojan.maran?
If it does, let us know the file name and location.

Happy Thanksgiving!!

I ran spybot again and it came out clean. I guess after running 5-6 different spyware cleaners, one of them actually deleted it. Thanks for the help! Happy belated T-day.

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recent Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
