What is a backdoor? help

Ok so I have Norton Antivirus 2010 Installed, and I keep getting a notification from norton that it has blocked a backdoor.trojan, but I get it like every 10 minutes, I don't know what to do O.o, what is a backdoor?

I'm not going into dangerous websites or anything, I'm just in facebook..
the location of the backdoor is windows/tmp/svchost.exe

A backdoor trojan differs from a trojan in that it also opens a backdoor to your system. They’re also sometimes call Remote Access Trojans (RAT). These are the most widespread and also the most dangerous type of trojan. They are so dangerous because the have the potential to allow remote adminstration of your system. As if a hacker were sitting at your keyboard, only worse. There’s almost no limit to what they can do. Some common uses:

  • Use your system and Internet connection to send spam (yes, the majority of spam is now generated by infected systems).
  • Steal your online and offline passwords, credit card numbers, address, phone number, and other information stored on your computer that could be used for identity theft, or other financial fraud.
  • Log your activity, read email, view and download contents of documents, pictures, videos and other private data.
  • Use your computer and Internet connection, in conjunction with others to launch Distributed Denial of Service (DDoS) attacks.
  • Modify system files, disable antivirus, delete files, change system settings, to cover tracks, or just to wreak havoc.
If you suspect you’re infected with a backdoor trojan, the first thing you should do is disconnect from the Internet to protect yourself, and others.

Here is the Symantec tutorial on how to remove BackDoor Triojan:

Click the file actions and see what options does it has ?

Heal, FIX or something like that? Sorry I have used Norton long back and so I don't remember the options

It depends on which backdoor trojan is on your computer. There are some that are not easily removed. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable. If the trojan is easily removed, keep an eye on any bank/credit card statements. Otherwise, it would be wise to contact those same financial institutions to apprise them of your situation.

As to the Symantec instructions, I do not agree with the recommendation that you disable System Restore. Clean the computer first, then create a fresh restore point and use Disk Cleanup to remove all but the last restore point.

If you have an anti-malware software installed, I suggest updating and scanning with that as well. Follow that up with an on-line scan.

Let us know if you need additional assistance.

Edit: Since you posted while I was composing, before scanning with another software, etc., I suggest you clear Temp Files. A simple program for that is ATF cleaner. The instructions are simple:

Download ATF Cleaner by Atribune from http://www.atribune.org/index.php?op...d=25&Itemid=25 . Save it to your Desktop.

Run ATF Cleaner
  • Double-click ATF-Cleaner.exe to run the program.
  • Click Select All found at the bottom of the list.
  • Click the Empty Selected button.
  • Click Exit on the Main menu to close the program.
  • Shutdown/restart the computer.


Follow that with further scans.
