How to properly scan a website for viruses?
In the current realities of the Internet, a rather frequent and big problem is viruses. This happens, most often, in very popular systems and plugins, since due to the huge demand for their use, they are more vulnerable.
Using vulnerabilities, viruses can be loaded onto the site, which in turn record important information and transmit it to third parties. The behavior of viruses on a site may not be displayed in any way and it is often quite difficult to notice their presence, which is why antivirus utilities should be used for sites that can help in finding viruses that have already been found.
If there is a suspicion that viruses have appeared on the site, then measures should be taken to remove them and find the source of infection. It is important to remember that removing viruses is only a partial solution, as without finding the source of infection, it is only a matter of time before viruses reappear.
To check the site for the presence of malicious code, as well as its subsequent cleaning, a set of checks and actions should be carried out :
1. The very first site check should be to check the files on the server. The most common problem with viruses occurs directly in the files that are used to operate the site system, since such files collect a lot of important information about visitors, actions, and so on.
2. An analysis of the loaded resources of the site should be a secondary check, with which online antiviruses can also help. When you go to the site, you should open the developer tools and in the Network tab check the downloaded resources for the presence of third-party plug-in scripts or files. Such files can often collect available information about visitors or perform multiple redirects to fraudulent services.
3. If viruses were found, then you should check the modification date of the infected files on the server. This date can roughly indicate when the infected file was last edited. Based on this information, you can proceed to subsequent checks and search for the problem.
4. It's worth backing up your site in case something goes wrong. When removing viruses, deleting important and necessary code, which has been replaced by the malicious code itself, can become a very real problem. Having a backup copy, you can restore the site's performance.
