Hello,

My antivirus's auto-protect quarantined and removed a trojan horse. I use Norton Internet Security 2009 and the following information was provided:


Eraser Version 109.2.0.124
Risk Name: Trojan Horse
Risk Category: Virus
Risk Type: File Based
Risk Level: High
Dependencies: No known dependencies
Affected Area: 1 File, 1 Browser Cache
Details (after clicking on "1 File"): e:\bonus.exe

I used Malwarebytes and it detected 1 infected registry data item:


HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoActiveDesktopChanges (Hijack.DisplayProperties)

I would like to check my system to see if there's any hidden part of the trojan horse remaining or anything else that looks fishy. Thank you for your help.

hi,

Looks like your AV did the job. Always check Malwarebytes for updates before a scan.

Heres some info to help remain malware free:

10 Tips for Reducing/Preventing Your Risk To Malware:

Simply knowing what constitutes a safe action on a computer and what may not will help you tremendously.

1) It is essential to keep your OS (http://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us),(Windows) browser (IE, FireFox) and other software up to date to "patch" vulnerabilities that could be exploited. Visit Windows Update frequently or use the auto-update feature. Staying updated is also necessary for web based applications like Java, Adobe Flash/Reader, QuickTime etc. Check there version status here. (http://secunia.com/vulnerability_scanning/online/)

2) Know what you are installing to your computer. Alot of software can come bundled with unwanted add-ons, like adware, toolbars and malware. Do not install any files from ads, popups or random links. Do not fall for fake warnings about virus and trojans being found on your computer and your then prompted to install software to remedy this. See also the signs (http://www.virusvault.us/signs1.html)that you may have malware on your computer.

3) Install and keep updated: one antivirus and two or three anti-malware applications. If not updated they will soon be worthless. If you frequently have malware then you should review your computer habits.

4) Refrain from clicking on links or attachments via E-Mail, IM, IRC, Chat Rooms, Blogs or Social Networking Sites, no matter how tempting or legitimate the message may seem.

5) Don't click on ads/pop ups or offers from websites requesting that you need to install software, media players or codecs to your computer--for any reason.

6) Don't click on offers to "scan" your computer. Install ActiveX Objects with care. Do you trust the website?

7) Set up and use limited (non-privileged) accounts for everyday use, rather than administrator accounts. Limited accounts (http://www.microsoft.com/protect/computer/advanced/useraccount.mspx) can help prevent *malware from installing and lessen its potential impact.*

8) Install and understand the limitations of a software firewall.

9) A tool (http://nsslabs.com/general/ie8-hardening-tool.html)for automatically hardening and securing Internet Explorer 8.0. Requires site registration for downloading. Changes some of the default settings of IE 8.0 Read the FAQ's.

10) Warez, cracks etc are very popular for carrying malware payloads. Avoid. If you install files via p2p (http://www.virusvault.us/p2p.html) networks then you are much more likely to encounter malicious code. Do you trust the source of the file? Do you really need another malware source?

A longer version in link below.

Happy Safe Surfing.

Hi shelf life,

Thanks for looking over my log and giving me the all clear.

I do have a few remaining questions though:

1. Someone started a thread at MalwareBytes Forum regarding the item that I recently quarantined:

Registry Data Items Infected:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoActiveDesktopChanges (Hijack.DisplayProperties) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.

They stated that this was a false positive. I was wondering if this was a remnant of the trojan virus that my AV quarantined and removed, or if it was okay for me to restore it.

This is the thread at MalwareBytes: http://www.malwarebytes.org/forums/index.php?showtopic=7653

2. Also, I was wondering if you could tell me why there are so many "file missing" entries in my hjt log. I'd like to know if there is a problem with my laptop before my warranty expires.

Thanks for your help!

hi mayanote

Your welcome. Looks like it can be restored from quarantine and added to the ignore list.
It had nothing to do with the file that Norton quarantined.

If all those files were really missing your computer would be a door stop.
Nothing to worry about, its a limitation in hjt when run on Windows Vista.
