Lsmo.exe is a Trojan horse infection that was spotted just recently. This particular malware is designed to perform various harmful activities inside the users’ computers and if you have been infected with it, we highly recommend you remove it as soon as possible.

For this reason, in the next lines, we have prepared a detailed removal guide with instructions on how to manually detect and delete the Trojan-related files and run a complete check on your system for any remains. We have also collected some basic information about this type of malware and in the paragraphs that follow, we will share with you the typical behavioral traits of Trojans, their most common infection and distribution methods as well as a few very helpful tips on how to prevent them in the future.

What issues may Lsmo.exe cause on the infected computer?

Once it is introduced to the machine, Lsmo.exe usually releases various infectious files. Unfortunately, without a proper antivirus program, the Trojan may remain hidden deep inside the system and the lack of visible symptoms of the infection may help it to silently perform its harmful tasks. The hackers, who control it, may program it to redirect users to malicious sites and prompt them to click on fake messages and links. Of course, this is nothing more than a scam because the users may be redirected to phishing sites and all the information they may introduce there may fall into the hands of the cyber criminals. This Trojan may also collect personal information including the user’s personal and business telephone, social security numbers, credit card details, keystrokes, passwords, and similar information. It may be programmed to reach the control center of the fraudsters and can be used for illicit activities unhurriedly. What is more, Lsmo.exe may be used to insert other malicious infections such as Ransomware, Spyware or other dangerous viruses inside the computer or simply to create a mess in the system. It is not uncommon that the Trojan may modify all major system files, may delete or corrupt the data, stored on the hard drives, manipulate the system processes and Registry keys or cause sudden crashes and general instability of the affected computer.

How does this Trojan spread?

Unfortunately, this harmful virus is spreading rapidly and has already successfully infected hundreds of computers. According to the latest reports, Lsmo.exe is distributed through different free downloads, links, attachments and exploit kits, which means that it can penetrate the victim’s system by taking advantage of vulnerabilities in non-upgraded software. In addition, this malware can be downloaded along with fake software updates, usually Java or Flash Player. While these programs are wholly legitimate, the cybercriminals take advantage of user confidence in them by linking infected files and promoting similar modified updates through insecure Internet sites. Therefore, we strongly recommend that you stay away from unknown sites and avoid downloading well-known software from them because such downloads may contain malicious files and may greatly damage your system. Needless to say, you should always upgrade your programs and protect your computer with powerful anti-virus software. Also, do not trust on spam emails, different free links and social shares that prompt you to click or download something. Always stick to reputed web content sources and avoid interaction with too-good-to-be-true offers and sketchy sites.

Step 1

The first thing that needs to be done prior to anything else is that you boot your PC into Safe Mode. If you are not sure how to do it, use this link to a guide on how to enter Safe Mode.

Step 2

Press Ctrl + Shift + Esc to open the Task Manager. Go to the Processes section and look for any suspicious-looking processes. Usually, malware processes use high amounts of RAM and CPU and also have shady description (or none at all). Right-click on those processes and select Open File Location. If you are sure that the process is coming from the virus, delete everything in the file location. Also, right-click on the process again and then select End Process.

Step 3

Press Winkey + R and type appwiz.cpl. Press Enter and in the newly opened window look for any shady program installs. Right-click on the suspicious programs and select uninstall. Follow the prompts to uninstall the sketchy application.

Step 4

Open the Run window again (Winkey + R), type msconfig and hit Enter. Go to the Startup section and from the list of programs, uncheck everything that seems shady or has an unknown or suspicious-looking manufacturer. Click on OK. On Windows 10, the startup programs list is in the Task Manager.

Step 5

Open the Start Menu and paste the following line in the search bar: notepad %windir%/system32/Drivers/etc/hosts. Click on the first result that gets displayed. A notepad file should open, look at the bottom of the text and see if there are any IP addresses below localhost. Write to us in the comments if you saw anything there.

Step 6

Type regedit in the Run search bar and hit Enter. When the Registry Editor opens, press Ctrl + F, type the name of the virus and select Find Next. If anything gets found, right-click on it and select Delete. Do this for all search results.

Additionally, manually navigate to the following directories and see if they have any folders/keys that look shady (with a lot of random numbers and letters):

  • HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Run
  • HKEY_CURRENT_USER > Software > Microsoft > Internet Explorer > Main
  • HKEY_CURRENT_USER > Software > Any other random directory

Delete everything that looks suspicious. If you are not sure whether to delete something, be sure to ask us in the comments.
