1. Accessing VirusTotal: Start by visiting the website at https://www.virustotal.com/. Here, you will find different options for scanning files or URLs.

2. Scanning a File:

• Click on the 'File' tab to upload a file from your device. After selecting the file, you'll confirm the upload and wait for VirusTotal to scan it. This method is particularly useful for checking whether a specific file is malicious or not^[4].
• Be cautious and avoid uploading sensitive files that might contain private data, as doing so can lead to potential information leakage.

3. Scanning a URL:

• If you want to scan a URL, you can click on the 'URL' tab, where you can copy and paste the URL for examination. VirusTotal will analyze the URL’s threat intelligence and reputation^[4].

4. Performing a Search:

• The 'Search' option allows you to input a wider array of identifiers, such as file hashes, IP addresses, or domains, to find related analysis reports. This is useful for identifying previously scanned items in the VirusTotal database^[4].

5. Reviewing Scan Results:

• After a scan, VirusTotal provides a detailed report summarizing the findings from various antivirus engines. You will see a score indicating how many engines flagged the file as malicious, along with other relevant details such as file hashes, submission dates, and community comments^[5][6][9].
• For URL scans, you'll similarly receive information about how many partners deemed it harmful and additional contextual data about the site^[5].

6. Using the API:

• For more advanced users, VirusTotal also offers an API that allows for automated queries, such as uploading files, retrieving scan reports, and searching for specific attributes programmatically. This can be particularly useful for integrating VirusTotal with other security workflows^[6][9].

7. YARA Rules and Advanced Search:
