A trojan virus is a type of malware that disguises itself as a legitimate program or file. Once installed on a computer, a trojan virus can give attackers remote access to the computer, allowing them to steal data, install additional malware, or launch other attacks. Trojan viruses are often spread through phishing emails or malicious websites, and they can be difficult to detect because they often do not exhibit any noticeable symptoms.
It is important to be aware of the risks of trojan viruses and to take steps to protect your computer from infection. Some of the most effective ways to detect trojan viruses include using a reputable antivirus program, keeping your software up to date, and being cautious about opening email attachments or clicking on links from unknown senders.
If you suspect that your computer may be infected with a trojan virus, there are a few things you can do to check. First, try running a scan with your antivirus program. If the scan does not detect any malware, you can try using a specialized trojan scanner. There are also a number of online tools that can help you to detect and remove trojan viruses.
