backdoor trojans

[tbon45]

no not what your thinking. the last couple time ive done a scan on my comp i found 2 backdoor trojans. what are they and where do they come from. and how do you get rid of it. im running win xp i have updated virus protection and a firewall and anti-spy. i also have a router to hook up my playstation. how could someon get in with all that. any help would be great thanks.

What are you using to scan with, and what trojans are you finding?

Also, just because you have a virus scanner, firewall, etc, you're not necessarily protected. A firewall is useless unless it's actually on and configured properly. Also, if you use Internet Explorer as a browser, keeping it updated gives you a better chance of staying clean, but it's still not a sure thing. It may be that way for other browsers, but IE gets targeted most, since it has the largest user base.

You say you have Win XP. Do you have Service Pack 2 and all other updates? That should help as well.

yeah everything i have is up to date i check for update at least twice a week. it dosnt tell me the name exactly just that it says backdoor trojan. i know im not 100% protected i just dont know what this and where it came from. ive only seen it twice so far. it says its in my documents and settings\emachians\temp local settings filebut i cant find the local settings file.

Okay, but what program are you using to scan for trojans and the like?

As for where they come from, it can be a lot of things. Websites can run harmful code on your computer if you don't have the security settings up high enough. Things you download can do the same thing, especially if they don't come from a trusted source. Also email attachments can be a problem.

And if I'm not mistaken, local settings is a folder, and possibly a hidden one.

i have adware 6.0 spybot and the anti spy from yahoo. i never had this until about a week ago when it first showed up.

Trojans, backdoors, droppers, what ever you call them, generally work in two stages. The first stage is the trojan or dropper which is a bit of java or such delivered along with a web page or e-mail. A scan often finds them laying around though they haven't caused any problems.

The second stage is for the code to try and install another (malicious) program. To do so, it needs to exploit a security hole or backdoor which will let it change things where java (or other security) should normally not allow the change to be made. It's a programming flaw in java or explorer, etc. which the dropper takes advantage of.

If you keep current on maintenance, you have a very low probability of trojans being able to drop something bad into your system because the maintenance updates fix the programming flaws the torjan exploits. The results is the tojan program gets "access denied" or equivalent when it tries to make the changes to your system.

Bottom line is that you may see trojans on your system (you can't stop them from coming) but they can't hurt you (because you have all the programming fixes installed) and the scanner/cleaners will warn you as they remove them.

Where they come from...

Most of the time you pick them up while surfing for porn on sites other than Literotica.

Literotica has a good record but a lot of picture or suposed picture sites do have trojans around in their code.

I catch 10 or 15 a week when surfing, my protection does catch them before they do anything, but it is really annoying that some sites appear to have them and do nothing to remove them, I have emailed sites and informed them about the ones my protection picks up, but I have never had a responce.

Keep on top of it and don't let it get you down.

Norton Internet Security is the only way to go. It includes norton firewall and norton antivirus. I have never heard any complaints about symantec products. They have great tech support too.

Norton

If you could find a different program other than norton anti-virus, do so. In my experience, as well as industry 'professionals' I know, Norton does not catch all that many virus' and does not update thier definitions as often as needed. Not to mention it is a resource hog (slows your computer a lot). Right now I'm using Nod32 and it's great. Good scanning config and lots of updates.

Ditto.

I've started tearing Norton (Symantec) off of my customer's computers even if they have a year left on their license.

The corporate edition is better, but not generally available to people unless thier employer gives them a deal.

There is a new version of AVG free (version 7) that looks good too.

If you are still using AVG Free Version 6 then you are no longer getting updates and need to upgrade.
