Trojan:O97M/Mountsi.D!ml – heuristic detection name that states about a trojan malware installed.

You should double-check before eliminating any programs or files related to the pop-up alert of the detection.

This Trojan:O97M/Mountsi.D!ml virus is one of many detections that can appear on the screen when your anti-malware tool checks the state of the machine that is possibly infected or affected by the intruder. You should pay close attention to random alerts from AV vendors because, in many cases, these warnings and virus detections are false positives and not related to anything on your particular machine. When your tool delivers you the message about positive findings, you can rely on the software and remove the threat, but a full scan and double-checking should help you determine if it is really needed.

Name Trojan:O97M/Mountsi.D!ml
Type Trojan/ false virus detection
Issue The AV program can show such false detections and scare the user without any reason, but serious infections like this can run to damage the machine, steal data, expose the system to more dangerous programs
Distribution Threats can spread silently when it comes to trojans and other sneaky viruses. Malicious macros,[1] infected or corrupted files, hacked sites can lead to infiltration of such virus too
Elimination You should remove Trojan:O97M/Mountsi.D!ml using a powerful anti-malware tool, so programs can get detected and terminated properly

Trojan:O97M/Mountsi.D!ml is a computer virus that can trigger processes in the background and make changes without your permission or knowledge. The worst thing about such silent intruders as trojans, malware, and worms is the distribution and shady methods of running needed procedures in the machine's background.

You might get exposed to malicious material and find the Trojan:O97M/Mountsi.D!ml installed later on. It happens quickly, and you cannot know when the infiltration happened unless you recall the file you downloaded or the page you already visited.

Malicious files with the payload of this malware can be dropped on the computer by another virus too. You may need to remove Trojan:O97M/Mountsi.D!ml and another program that triggered the infection in the first place. This is why anti-malware tools are needed, and experts[3] recommend keeping such tools on the system and running them more often.

You should avoid these infections as much as possible, but it is not that easily achievable. Trojans can be malware droppers or downloaders and lead to infections of damaging threats like ransomware. Threat behaves as it is coded for, so you might not even notice Trojan:O97M/Mountsi.D!ml, but only encounter the later virus that caused damage.

Running ReimageIntego or a PC tool can help indicate what issues are caused by the infection and other problems that are not related to malware infections.

If you find files, suspicious programs, or different additions on the machine, you should try to determine if the infection alert is really associated with malware pieces like Trojan:O97M/Mountsi.D!ml. You can try to find processes running on resources and files that trigger suspicious behavior. Rely on proper AV tools and security programs before you delete anything from the machine.

Trojan payload gets dropped directly on the computer

Trojans and other malware that is spreading around using malicious files, shady websites, or other intruders can mask various tasks in the background and hide traces of the infection entirely. It is designed to use common file types and drop payload files using EXE or DLL files via email attachments and directly from pages and pirated software packages.

Some exploits and vulnerabilities can be used to infect computers with such malware. Remote access tools or scams can be set to result in these trojan attacks too. Internet is not a safe place, so make sure to run security tools more often since malicious emails and even suspicious files can be indicted, and virus infiltration avoided.

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
