Hi,

I believe that I've been infected with the SDBot, as I am having symptoms very similar to those reported by another poster on this site (http://www.bleepingcomputer.com/forums/lofiversion/index.php/t328998.html)

In short, every once in a while a Eset security suite window pops open telling me that allxt.com/borders.phphas been blocked. There may be more to the message in the window, but this is all I could copy down in the time the window remained open. I read the about seriousness of this worm from the post I've linked above. I've changed the password to the only banking website I use, however reinstalling my operating system is not really an option since my operating system (Windows XP Pro) came preloaded on my computer.

I've been following the advice given in the post I've linked above. Fortunately I already has Malwarebytes loaded on my computer, updated it, and ran a quick scan. I've enclosed the log report below. I will continue to follow the instructions outlined in the post I've linked and I'll post the results of each my scans in this thread. If someone could take a look at them and let me know if there is more I need to do, I would REALLY appreciate it. Thank you very much!

Hello, As in the other thread we will need to run these as I feel your issues still exist,correct?

These Are long scans

Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.

alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options.

Hi boopme,

Thanks for your assistance. I did run through each of the steps that you outlined, with the exception of Dr. Web CureIt, which stalled a couple of times. After some consideration, I decided to get Windows 7 and upgrade my operating system. I just didn't want to take the chance that some of my information may eventually get into the hands of the hackers. I ran Super Antispyware twice and the 2nd time it came out clean. I also got clean scans from Eset and Trend Micro online scans.

I do have a couple of questions for you. I originally got this worm because I was visiting what appeared to be a legit news site that contained a video on a news story of interest. The embedded video player asked me to update my plugin in order to watch the video, I downloaded the plugin by clicking on the link provided, and then installed it. In hindsight, very stupid I know. I guess I get so used to seeing plugin upgrades for these video players, I just wasn't thinking.

What really concerned me was that I got the following email, sent to an email address I swear I never supplied to Paypal:

The email also had a header containing "To:UserService@orange.fr Reply To: jjndpt@accounts.net" This is not my email address and the whole thing looked too suspicious and so I did not reply. I went through and changed any passwords on accounts that contain my credit card information (even though the credit card number isn't given in it's entirety on any of these accounts. Amazon.com is one example), and I've also notified my bank and they are sending me a new credit card with a different number.

I have some questions:

1.Since I have done a fresh install of Windows 7 (I couldn't do the "in place" upgrade since I had Windows XP), how likely is it that my computer has remnants of the worm and that my ID, bank information, etc. might be stolen in the future?

2. Other than passwords to email accounts and any websites that contain my credit card information, what other precautions should I take? I didn't bother changing the passwords to websites that do not contain any credit card/banking information (a web forum like Bleeping Computer, for example). Should I change ALL passwords, regardless of whether they are for websites that have my credit card info stored on the site?

3. I use Roboform to store my passwords. I also sync them to their servers. I created an entire new account with the Roboform servers and synced my new passwords to this new account. Fortunately I hadn't stored any financial information within my Roboform toolbar. Are there any precautions I should take with Roboform to ensure that my new password information cannot still be stolen via this same worm?

4. Do you have any other advice for me regarding things I might do so that these hackers cannot get my ID, credit card information, banking information, etc in the future?

This is a whole new experience for me. I've never had difficulties with viruses/worms and I'd really like to never repeat this experience again. Thanks very, very much for your help!

Hello I 'll have to look at robForm..
Here are some of our quietman7's Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:

Hi boopme,

Thanks once again for all of your help. As I stated in my last post, I dumped my Windows XP Pro OS and did a clean install of Windows 7 on my computer. Thus far, everything seems to be running smoothly. However, my previous data Windows XP data has been saved to a folder called Windows.old on my hard drive. Not only is this file taking up quick a lot of space on my hard drive, but I fear that, if it still has remnants of the SDBot worm, it might somehow reinfect my computer. I've read varying accounts of whether this it's safe to simply delete this folder all together, or whether one should back it up before deleting. I have an external hard drive and could considerably back it up to this drive, but I also don't want to infect this drive if the worm remains on the Windows.old folder. Do you have any words of advice for me? Should I just dump the Windows.old folder since everything seems to be working smoothly since the clean install of Windows 7 Pro? Is there any reason for me to keep this folder? I have backed up any data from My Documents (photos, music, etc) that I would need and have already reinstalled any software directly from the install discs onto Windows 7. I just want to make sure that all traces of the worm have been completely eliminated. Thanks again for all of your help!

It is safe to delete the folder. If you want to back up and save anything.
2 guidelines/rules when backing up

1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe/.scr/.htm/.html/.xml/.zip/.rar files as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.
