Hi stevo7388
Click here (http://www.trendsecure.com/portal/en-US/threat_analytics/HJTInstall.exe) to download HJTInstall.exe
Save HJTInstall.exe to your desktop.
Doubleclick on the HJTInstall.exe icon on your desktop.
By default it will install to C:\Program Files\Trend Micro\HijackThis .
Click on Install.
It will create a HijackThis icon on the desktop.
Once installed, it will launch Hijackthis.
Click on the Do a system scan and save a logfile button. It will scan and the log should open in notepad.
Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
Come back here to this thread and Paste the log in your next reply.
DO NOT use the AnalyseThis button, its findings are dangerous if misinterpreted.
DO NOT have Hijackthis fix anything yet. Most of what it finds will be harmless or even required.

Hi
One or more of the identified infections is a backdoor trojan.
This allows hackers to remotely control your computer, steal critical system information and Download and Execute files
I would counsel you to disconnect this PC from the Internet immediately. 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, and it would be wise to contact those same financial institutions to apprise them of your situation.
Though the Trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of Trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:
How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud? (http://www.dslreports.com/faq/10451)
When Should I Format, How Should I Reinstall (http://www.dslreports.com/faq/10063)
We can attempt to clean this machine but I can't guarantee that it will be 100% secure afterwards.
Should you have any questions, please feel free to ask.
Please let us know what you have decided to do in your next post.

i shall back up all my files and folders and addresses etc.. and re-format the harddrive. thankyou for responding so quickly.
Hi
Thanks for the info.
Do you need any help with reformatting?
stevo7388

no, i dont need any help with reformatting. i have some experience with it. disc in, reboot and wait. install, install and install. i know the drill... thanks anyway.
Hi
OK, thanks for letting me know.
See below for my tips for the future:
Looking over your log, it seems you don't have any evidence of a third party firewall.
As the term conveys, a firewall is an extra layer of security installed onto computers, which restricts access to systems from the outside world. Firewalls protect against hackers and malicious intruders. I want you to download a free firewall NOW from one of these excellent vendors:
1) Comodo (http://www.personalfirewall.comodo.com/) (Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage")
2) Online Armor (http://www.tallemu.com/online_armor_free.html)
3) Sunbelt/Kerio (http://www.sunbelt-software.com/Kerio-Download.cfm)
4) Agnitum (http://www.agnitum.com/products/outpostfree/download.php)
5) ZoneAlarm (http://www.zonelabs.com/store/content/catalog/products/sku_list_za.jsp?dc=12bms&ctry=US&lang=en&lid=nav_za) (uncheck ZoneAlarm Spy Blocker during installation if you choose this one)
If you are using the built-in Windows XP firewall, it is not recommended as it does not block outgoing connections. This means that any malware on your computer is free to "phone home" for more instructions. Simply put, Windows XP contains a mediocre firewall. This firewall is NO replacement for a dedicated software solution. Remember to use only one firewall at the same time.
Make your Internet Explorer more secure - This can be done by following these simple instructions:
From within Internet Explorer click on the Tools menu and then click on Options.
Click once on the Security tab
Click once on the Internet icon so it becomes highlighted.
Click once on the Custom Level button.
Change the Download signed ActiveX controls to Prompt
Change the Download unsigned ActiveX controls to Disable
Change the Initialize and script ActiveX controls not marked as safe to Disable
Change the Installation of desktop items to Prompt
Change the Launching programs and files in an IFRAME to Prompt
Change the Navigate sub-frames across different domains to Prompt
When all these settings have been made, click on the OK button.
If it prompts you as to whether or not you want to save the settings, press the Yes button.
Next press the Apply button and then the OK to exit the Internet Properties page.
Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.
Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com (http://www.windowsupdate.com) regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.
Install Malwarebytes' Anti-Malware - Malwarebytes' Anti-Malware is a new and powerful anti-malware tool. It is
totally free but for real-time protection you will have to pay a small one-time fee. Tutorial on installing & using this product can be found below:
Malwarebytes' Anti-Malware Setup Guide (http://bfccomputers.com/index.php?showtopic=1644)
Malwarebytes' Anti-Malware Scanning Guide (http://bfccomputers.com/index.php?showtopic=1645)
Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.
A tutorial on installing & using this product can be found here:
Using SpywareBlaster to protect your computer from Spyware and Malware (http://www.bleepingcomputer.com/tutorials/tutorial49.html)
Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.
Here are some additional utilities that will enhance your safety
MVPS Hosts file (http://mvps.org/winhelp2002/hosts.htm) <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your computer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
Winpatrol (http://www.winpatrol.com/) <= Download and install the free version of Winpatrol. a tutorial for this product is located here:
Using Winpatrol to protect your computer from malicious software (http://www.winpatrol.com/features.html)
Stand Up and Be Counted ---> Malware Complaints (http://www.malwarecomplaints.info/index.php) <--- where you can make difference!
The site offers people who have been (or are) victims of malware the opportunity to document their story and, in that way, launch a complaint against the malware and the makers of the malware.
Also, please read this great article by Tony Klein So How Did I Get Infected In First Place (http://castlecops.com/postlite7736-.html)
Since this issue appears to be resolved ... this Topic has been closed. Glad I could help.
Note: If it has been five days or more since your last post, and the helper assisting you posted a response to that post to which you did not reply, your topic will not be reopened. At that point, if you still require help, please start a new topic and include a fresh HijackThis log and a link to your previous thread.
If it has been less than five days since your last response and you need the thread re-opened, please send me or your helper a private message (pm). A valid, working link to the closed topic is required.
