Web page Trojans are vulnerable to forgery and anti-virus software does not have the ability to scan and kill web page Trojans. In this case, we can identify web page Trojans based on the performance of computers. Generally, computers infected with web Trojans have the following symptoms:

1. Slow system response: attackers often exploit Internet Explorer vulnerabilities to create web page Trojans. Generally, they exploit this vulnerability to execute attack code by constructing a buffer that overflows the browser or component with a large amount of data. Therefore, when a user suffers an overflow webpage Trojan attack, the system usually responds very slowly, the CPU usage is high, the browser window does not respond, and the task manager cannot be forcibly disabled.

For large memory computers larger than 1 GB, after being infected with web Trojans, the task manager can still be opened. If you find that the process in Task Manager is more than 90% in IE browser, you can determine that your computer is infected with web Trojans. In addition to the above phenomena, computer hard disks infected with web Trojans perform frequent write operations, and the hard drive indicators are on.

2. Process loading changes: Once a web page Trojan is loaded successfully on your computer, it also occupies a process during running. However, some attackers may disguise the trojan program as a normal program, or steal the system process, making it hard for common users to find out.
