When a virus file analysis gets into your computer, it can cause several types of damage. The most common type of malware is designed to replicate itself and spread to other computers, and it can also do things like steal information or delete files. Antivirus technologies can detect infected files and quarantine them. In some cases, the antivirus technology may be able to repair a damaged file by removing the infected code.

Malware can use many techniques to avoid detection, including modifying files and hiding from signature-based detection tools. To understand how a malicious program operates, you can use static analysis tools like VirusTotal or reverse-engineering tools like x64dbg, IDA Pro, and Ghidra.

Step-by-Step Guide to Virus File Analysis and Protection

Static file analysis helps you find potentially dangerous files and folders in your organization. You can find out which files have read, write, or execute permissions that can be exploited by insiders and external entities. You can also pinpoint duplicate and non-business files that are consuming disk space. Finally, you can track file permission hygiene to identify inconsistencies that could indicate an attempt by insiders to gain unauthorized access.

While static file analysis can provide valuable context, it is often not enough to detect certain types of threats. For example, polymorphic and metamorphic malware are often designed to evade signature-based detection by constantly changing their code. Additionally, a standard kill chain may consist of multiple executables that trigger each other, making it difficult to analyze with static methods alone. For these reasons, it is important to pair static analyses with dynamic analysis in a risk-based approach.
