Trojan.StartPage: Best Threat Protection and Fixing Guide 2025

Trojan.StartPage is a malicious software that poses a serious threat to individuals and organizations alike. It belongs to the category of malware known as a botnet, which allows cybercriminals to remotely control a network of infected computers for malicious purposes.

One of the key features of Trojan.StartPage is its ability to perform cryptojacking, a form of unauthorized mining of cryptocurrencies using the victim’s computer resources. This is achieved through CPU hijack attacks, where the malware injects cryptojacking scripts into the victim’s system without their knowledge or consent.

As a result, those affected by Trojan.StartPage may experience a significant slowdown in their computer’s performance, increased electricity bills, and potential damage to their hardware due to the excessive strain on the CPU. Moreover, the unauthorized mining of cryptocurrencies can also lead to financial losses for the victims.

Who is most affected by Trojan.StartPage?

• Individuals who download files from untrustworthy sources
• Employees who use company devices for personal use
• Organizations with weak cybersecurity measures
• Users who do not regularly update their antivirus software

Trojan.StartPage, also known as StartPage, is a type of Trojan horse malware that first emerged in the early 2000s. It is designed to redirect a user’s homepage to a malicious website, usually one that is filled with advertisements or other harmful content.

Discovery and Evolution

The Trojan.StartPage malware was first discovered by security researchers who noticed a pattern of users reporting unauthorized changes to their browser settings. Upon further investigation, it was found that a Trojan horse was responsible for these changes, hence the name Trojan.StartPage.

Over the years, Trojan.StartPage has evolved to become more sophisticated and harder to detect. It has been known to disguise itself as legitimate software or hide within other files to avoid detection by antivirus programs.

Notable Incidents

• 2005: Trojan.StartPage was involved in a large-scale phishing attack that targeted banking information of thousands of users.
• 2010: A variant of Trojan.StartPage was discovered that not only changed browser settings but also stole sensitive information such as passwords and credit card numbers.
• 2015: Security researchers uncovered a new strain of Trojan.StartPage that was spreading through infected email attachments, causing widespread disruption.

As technology continues to advance, so too does the sophistication of malware like Trojan.StartPage. It is important for users to stay vigilant and keep their antivirus software up to date to protect against these types of threats.

Trojan.StartPage is a type of malicious software that is designed to spread and infect computers through various vectors and methods. Understanding how it spreads is crucial in preventing and protecting against such threats.

Infection Vectors:
