DrMadhead Posted June 30, 2021 ID:1466553 Share Posted June 30, 2021 (edited) Hello, Two days ago my computer was infected by some malicious malware. I ran malwarebyte, ESET scan, and some other antimalware programs. I was able to remove most of the malware, but I noticed that my command prompt opens and closes quickly every so often. I suspect that it has something to do with windows command processor because this program only appears on the start up manager of norton security, and does not appear on task manager. Furthermore, when I try to turn off the start up option for windows command processor, it keeps re-enabling itself. What do I do?

Maurice Naggar Posted July 1, 2021 ID:1466608 Share Posted July 1, 2021 (edited) Thanks for the report file. As I think I understood what you described at the start. There is some kind of a "command window" that you see briefly at the time of Windows startup. That is what you have some concern about. And that you had had some kind of malware a couple of days ago. I will be guiding you to scan, check for malware. . I see this pc has ESET Security. A excellent security app. Did you do a scan with ESET today ? . [ 1 ] As a next basic step, Please set File Explorer to SHOW ALL folders, all files, including Hidden ones. Use OPTION ONE or TWO of this article https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html [ 2 ] There are a couple of hidden files under appdata/roaming, which will be removed. There are 2 files flagged by Defender as threats that will be removed. This script will also run the Windows System File Checker to check the system files. There is a suspicious Task for "Firefox Default Browser Agent DFF4CD17B6770B9A" that will be removed. The script Fixlist.txt needs to be saved to the same folder that contains FRSTENGLISH.exe / it is on Downloads Please save the (attached file named) FIXLIST.txt to the Downloads folder Fixlist.txt The custom script on this post is ONLY for this machine and NO other. Please be sure to Close any open work files, documents, any apps you started yourself before starting this. If there are any CD / DVD / or USB-flash-thumb or USB-storage drives attached, please disconnect any of those. The system will be rebooted after the script has run. Start the Windows Explorer and then, to the Downloads folder. RIGHT click on FRSTENGLISH.exe and select RUN as Administrator and allow it to proceed. Reply YES when prompted to allow to run the tool. If the tool warns you the version is outdated, please download and run the updated version. IF Windows prompts you about running this, select YES to allow it to proceed. IF you get a block message from Windows about this tool...... click line More info information on that screen and click button Run anyway on next screen. on the FRST window: Click the Fix button just once, and wait. PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. If you receive a message that a reboot is required, please make sure you allow it to restart normally. The tool will complete its run after restart. When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run. Please attach the FIXLOG.txt with your next reply later, at your next opportunity. We will do more later. You should take some time, to run a new scan with your ESET Security. Let me know what that reports. Edited July 1, 2021 by Maurice Naggar corrected font issue Link to post Share on other sites More sharing options...

Maurice Naggar Posted July 1, 2021 ID:1466698 Share Posted July 1, 2021 Thank you. The run is good. I do expect that you are not seeing a odd-command-window screen flash at windows startup. Our program, Malwarebytes for Windows can detect and remove most malware with no further actions required for free. Please download, install, update and do a Threat Scan with Malwarebytes and post back the log Then, locate the Scan run report; export out a copy; & then attach in with your reply. See https://support.malwarebytes.com/hc/en-us/articles/360038479194-View-Reports-and-History-in-Malwarebytes-for-Windows-v4 Let me know how the situation is after that. 😃 Link to post Share on other sites More sharing options...

Maurice Naggar Posted July 3, 2021 ID:1467183 Share Posted July 3, 2021 I am glad to have worked with you. We can proceed with cleanup of tools we used. To remove the FRST tool & its work files, do this. Go to your Downloads folder. Do a RIGHT-click on FRSTENGLISH.exe & select RENAME & then change it to UNINSTALL.exe . Then run that ( double click on it) to begin the cleanup process. Delete mbst-grab-results.zip Delete mb-support-1.8.4.896.exe on Desktop Adwcleaner you may keep & run on-demand as desired to check for adwares. Any other download file I had you download, you may delete. [ BEST PRACTICES ] Backup is your best friend. Keep backups of your system on a regular basis to offline storage & keep those safe. https://forums.malwarebytes.com/topic/136226-backup-software/ It is not enough to just have a security program installed. Each pc user needs to practice daily safe computer and internet use. Best practices & malware prevention: Follow best practices when browsing the Internet, especially on opening links coming from untrusted sources. First rule of internet safety: slow down & think before you "click". Never click links without first hovering your mouse over the link and seeing if it is going to an odd address ( one that does not fit or is odd looking or has typos). Free games & free programs are like "candy". We do not accept them from "strangers". Never open attachments that come with unexpected ( out of the blue ) email no matter how enticing. Never open attachments from the email itself. Do not double click in the email. Always Save first and then scan with antivirus program. Pay close attention when installing 3rd-party programs. It is important that you pay attention to the license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed. Take great care in every stage of the process and every offer screen, and make sure you know what it is you're agreeing to before you click "Next". Use a Standard user account rather than an administrator-rights account when "surfing" the web. See more info on Corrine's SecurityGarden Blog http://securitygarden.blogspot.com/p/blog-page_7.html Don't remove your current login. Just use the new Standard-user-level one for everyday use while on the internet. Do a Windows Update. Make certain that Automatic Updates is enabled. https://support.microsoft.com/en-us/help/12373/windows-update-faq Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware. For other added tips, read "10 easy ways to prevent malware infection" https://blog.malwarebytes.com/101/2016/08/10-easy-ways-to-prevent-malware-infection/ Stay safe. I wish you all the best.
