Win32/Kryptic.AWC Trojan
During a Google search I clicked one of the links. The page loaded, but changed its content automatically after about five seconds. The web browser (Firefox) crashed. NOD32 popped up saying it quarantined a file:
Object: h**p://redirectcounter2.com/egvwxy2.exe It said it was a variant of the Win32/Kryptic.AWC trojan. It's impossible to delete this file. The quarantine warning keeps popping up every second or so. While GMER was doing its thing an executable (.../Mozilla Firefox/a.exe) popped up in a "DOS" window. The window is black with the cursor jumping around when active and in the foreground. When GMER was done I noticed I couldn't access my USB drive any more. Any help will be greatly appreciated.

Re: Win32/Kryptic.AWC Trojan
Please visit this webpage for download links, and instructions for running ComboFix tool:
http://www.bleepingcomputer.com/comb...o-use-combofix Please ensure you read this guide carefully and install the Recovery Console first. The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode. This allows us to more easily help you should your computer have a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time. Once installed, you should see a blue screen prompt that says: The Recovery Console was successfully installed. Please continue as follows:
When the tool is finished, it will produce a report for you. Please include the following reports for further review, and so we may continue cleansing the system: C:\ComboFix.txt New dds log. A word of warning: Neither I nor sUBs are responsible for any damage you may have caused your machine by running ComboFix. This tool is not a toy and not for everyday use.

Re: Win32/Kryptic.AWC Trojan
Hi Blade81,
Thanks a bunch for your help. There were a few other symptoms after the infection. I couldn't see some files on my desktop (ark.txt, attach.txt). The Windows Task Manager wouldn't start. Neither would Thunderbird nor Firefox (were still running, but couldn't be killed with the task manager not working) nor ComboFix. I restarted the computer and things seem to be working properly. Here are the logs. Again, thanks for your help.

Re: Win32/Kryptic.AWC Trojan
Hi,
Could you run some web searching and let me know if there're any issues with the results there?

Re: Win32/Kryptic.AWC Trojan
Thanks for your quick response.
I did a few internet searches, and there were no problems, no redirections or pop-up windows or anything. Also, I was able to remove the egvwxy2.exe from the NOD32 quarantine list after the computer restart. But the a.exe file is still in the Program Files/Mozilla Firefox folder. Thanks, No-Know |

Re: Win32/Kryptic.AWC Trojan
Ok. Thanks for the feedback. Let's run one more check.
Open notepad and then copy and paste the bolded lines below into it. Go to File > save as and name the file check.bat, change the Save as type to all files and save it to your desktop. @ECHO OFF SWSC QUERYEX OPTIONS= config TYPE= DRIVER GROUP= "SCSI MINIPORT" >logit.txt START Logit.txt DEL %0 Double-click on check.bat file to execute it. Notepad should open up with Logit.txt file contents. Please post that back here.

UPDATING WINDOWS AND INTERNET EXPLORER IMPORTANT: You Need to Update Windows and Internet Explorer to protect your computer from the malware that is around on the Internet. Please go to the windows update site to get the critical updates. If you are running Microsoft Office, or any portion thereof, go to the Microsoft's Office Update site and make sure you have at least all the critical updates installed (Free) Microsoft Office Update. 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.

The following are recommended third party programs that are designed to keep your computer clean. A link as well as a brief description is included with each item.
Just a final reminder for you. I am trying to stress these two points. UPDATE UPDATE UPDATE!!! Make sure you do this about every 1-2 weeks. Make sure all of your security programs are up to date. Visit Microsoft's Windows Update Site Frequently - It is important that you visit 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. Once again, please post and tell me how things are going with your system... problems etc. Have a great day, Blade
