I got infected with a trojan yesterday, accidentally clicked on something and it popped up that screen that tries to get me to clean my computer (happened to hubby a while back, mine looked a little different though). So I followed the steps given here that we followed when he had his problem (his computer has been clean since):

http://www.bleepingcomputer.com/virus-removal/remove-av-security-suite (because he had the AV Security Suite thing and mine looked similar)

Malwarebytes found 10 items, so I removed them and restarted. Things seemed fine until I tried to log on to paypal, and got a box that asked me for lots of personal info before it would let me continue. Had to close that and then Firefox crashed so I knew I still had something. I checked the startup registry and found rundll32 "C"\Users\blah blah blah\DpiSvr32.dll" CreateProcessNotify

I removed that, restarted, changed all my passwords, and things seem fine now, no problem of any kind. Ran Malwarebytes again and everything looked good. I didn't see this DpiSvr32.dll on the list so didn't know how harmful it was or exactly what it was, but just wanted to make sure I was clean.

I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the Posted Image button.

I'm running the scan now and will post the results, so far found one threat. Do you recommend this as continuous anti-virus protection over Norton 360? Is there a better anti-virus program out there? I've been using Norton for years and obviously it's not doing its job so I'm shopping for something better!

Let's make sure you are clean first, but there are several good AV's, some free, I like Eset for their online service.

I'm not sure what that is or how to do that, can you help? When I exported the results in a text file I saved it to my desktop and this was all that was in it:

C:\Users\Kim\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\14\a6c344e-103ef063 Java/Exploit.Agent.NAA trojan deleted - quarantined

I hope I exported the correct thing, but let me know if I need to do something else.

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Ok will do, but just to know, what does this do that hasn't already been done by MB and ESET? I don't have any problem doing it and don't question it, just like to know what it does.

Thanks!
Kim

This is why I keep wanting you to dig deeper, we are looking for evidence of a hidden rootkit that MBAM or Eset might miss.

I disabled all my AV and disconnected from the internet per instructions. Not sure if I should keep trying. I'll wait for your reply before continuing.
