What programs have you used? MBAM is a good one, but no single spyware scanner gets everything.

possumbarnes,

Avast, SuperAntiSpy & Spywareblaster ... at the moment

Update...just scanned another computer connected to the same router & picked up the same infection or perhaps it's a false positive.

If you can run a fully updated complete scan with MBAM in normal mode and run a fully updated complete scan with SAS in safe mode and come up clean on both, then I think its safe to say it's dead. Do the same on every computer on that network to be safe.

Thanks Bub,

Why SAS in safe mode?

Here's something strange... I did boot up in safe mode & for some reason my computer, (fans perhaps) sounded as if they were jet engines. Sure, things can get a little noisy on start up but this did not cease to the point where it actually started to smell like it was burning... slightly. I shut down & restarted in normal mode & the machine slowed down. While this thing was running at top speed, I checked to see if something was running & ... nothing.

Your fan must have a speed control and when the processor load increases, so does the heat
SAS is designed to run in safe mode
Running in normal mode, it might not catch some things
Try a Dr. Web scan. in safe mode, and post the results


Please download Dr.Web CureIt, the free version & save it to your desktop. DO NOT perform a scan yet.

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. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Regarding your initial infection

IMPORTANT NOTE: One or more of the identified infections was a backdoor Trojan. Backdoor Trojans, IRCBots and Infostealers are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge. Read Danger: Remote Access Trojans.

If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control again. and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the infection was identified and removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because this malware has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

"When should I re-format? How should I reinstall?"
"Help: I Got Hacked. Now What Do I Do?"
"Where to draw the line? When to recommend a format and reinstall?"

Thanks Guys but as indicated in some earlier responses, which seem to have been removed, there was a MBAM fp in the latest update, as confirmed by MBAM staff...that's all.

garmanma,

ps- I know this is more of a side topic but....in regards to my jet engines...

Your fan must have a speed control and when the processor load increases, so does the heat


I thought less was running in safe mode so why would my processor load increase?

And..I can't seem to boot in safe mode without the machine sounding like it's going to explode, oddly enough, so considering this, is it still wise to run SAS not in safe mode?

Thanks

Obviously something isn't right
Open Task Manager and see what's running when you're in safe mode

Mark,

Here's the list, however, the System Idle Process is at 99% despite the machine running loudly. It didn't quite kick in to high gear this time but still much too noisy. Normally, when I start up, the machine seems to be louder than it used to be but it does quiet down once everything loads. Again, the machine does run louder than it use too, not only on start up. It's only two years old. I have another 5 year old w/ XP Pro, both Gateways, that is extremely quiet.

task manager
explorer.exe
wmiprsve.exe
svchost.exe
AAWService.exe
svchost.exe
svchost.exe
services.exe
Isass.exe
csrss.exe
winlogon.exe
smss.exe
System
System Idle Process

Thanks!

My guess would be a fan going bad

Just a hunch, but I bet if you uninstalled AdAware things might return to normal
Just a thought

Thanks.... fyi...I just installed AdAware once I realized that SAS couldn't be used properly... safe mode acted this way prior to AdAware.

Update Mbam and run one more full scan
If that backdoor bot still comes back, I suggest submitting a HJT log



Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

[color=green]Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.[/colo
