OInstall.exe Virus


OInstall.exe is a Trojan horse infection known for its multifunctional malicious abilities. Hackers can use OInstall.exe to establish remote control over a given computer and to run various harmful processes and tasks on it without the victim’s knowledge.


The OInstall.exe Virus

As far as history is concerned, the term Trojan horse comes from the ancient Greek myth about the wooden horse used to conquer the city of Troy. When it comes to computing, a Trojan is a particularly dangerous, very common and very nasty virus, which – much like its historical equivalent – is mounted stealthily into the system and can be used for various criminal purposes. This is especially true for OInstall.exe which is one of the latest representatives of this notorious malware family.

What can hackers use OInstall.exe for?

Depending on their criminal intentions, the hackers who stand behind OInstall.exe can use it for a number of malicious activities. Your files could be in danger if the crooks want to have fun with them and delete, replace, modify, duplicate or corrupt them. It may also be considered amusing for the hackers to just crack, hack and crash some of the system’s processes and software. But compared to what is next, this is probably the least disturbing thing that can happen if you have OInstall.exe on your machine.

One of the most dreadful uses of Trojans is for the distribution of Ransomware threats. Usually, the Trojans are used to find weaknesses in the system which can be exploited by other malware. In the case with Ransomware, the Trojan acts as a backdoor and ensures the swift insertion of the infection into the target computer.

Another fearful ability of Trojans is to access and steal all types of data they want. Such threats can collect banking information so you can be robbed, account information so hackers can steal your identity, keystrokes so that your passwords are revealed, as well as any business or personal information that you keep on your computer. This can happen when the malware secretly activates your camera and microphone and monitors your activities, conversations, and correspondence.

The fact that OInstall.exe could be used for so many malicious activities makes it an unpredictably dangerous piece that needs to be removed at once.

Can Trojans be avoided or deleted?

It is possible to avoid Trojan threats and other serious infections or at least limit your chances of landing one if you follow some basic safety rules. For instance, you should stick only to reliable and reputed web content sources and avoid anything like cracked program packages, torrents, pirated materials, web pages with sketchy ads and links, spam messages and e-mails from unfamiliar senders. This is the foundation of safe web surfing and is essential to your online safety. Investing in a premium-class antivirus program to detect and remove harmful programs on time is another very important thing. You’ll find a lot of professional system security tools online but if you need a trusted one right now, make sure you check the program on this page.
