Infection of a site or part of files with viruses is a real problem that can happen to almost every resource. And, if today you have done everything possible to resist the attack of well-known “invaders,” this does not mean that tomorrow your site will not be infected by new malicious code.
In some cases, the computer can work even with the collected Trojan bouquet. But for a website, a virus caught on it can turn out to be a natural death. After all, search engines regularly check resources and block those that contain viruses or malicious codes. And the point here is not at all about the harmfulness or legibility of Yandex and Google. Simply in this way, search engines protect users, bearing responsibility for the quality of their search results.

How to protect your site from virus attacks

To protect your site from malware, find possible vulnerabilities and eliminate them:

  • regularly update the CMS system;
  • switch to the secure https protocol if you have not already done so;
  • use a secure login and password for the admin panel;
  • do not provide access to the site to third parties;
  • use high-quality hosting and configure modules on it to check the resource for viruses or install special scripts;
  • additionally, check the resource using special online services;
  • if you found a problem, try to fix it as soon as possible.

Now we will look at how quickly and inexpensively you can check a site for malicious code and programs.

Ways to scan a website and files for viruses

There are 4 main types of resource analysis to protect it from viruses and malware:

1. Special modules from a hosting provider Most hosting providers have such means of protection against viruses and hacking for resources whose owners use their services. If you still do not know about such a hoster’s possibility, we recommend that you contact him and clarify this issue. And this is one of the most reliable ways to detect malicious code. Plus, you can set a scan script: specify how often the program will scan the resource and how it will notify you of the problem. In some cases, antivirus modules also offer the option to remove malicious scripts automatically, but it is better to remove them manually.

2. Installing scripts or plugins for protection on the site
There are also special plugins developed for popular CMS systems and platforms for scanning sites for viruses and blocking attempts to hack and introduce malware. If you find any problem, you will receive an e-mail, and it will be in the admin panel.

3. Online scanning of a resource for viruses and the presence of malicious code. You should not rely only on this method of scanning a site. Still, in combination with the above, it can also help save you from many serious problems and find malicious scripts and code fragments that interfere with the regular operation of the resource and threaten security visitors. It can also lead to blocking by search engines.

4. Checking for security problems in Google Search Console. Search engines periodically check the sites registered in their database, looking for malicious codes. They do this automatically and in the background without distracting you or slowing down your site. Thus, they fight hackers, helping resource owners to fend off attacks and protecting system users. But this is not enough, and to sleep well and not be afraid of pests, you need to monitor the situation independently. The Security Issues report will show whether the Google search engine detects a hacked content, unwanted or malicious software, social engineering that can harm users. The report will indicate on which pages and when the problem was found.

To protect the personal data of users, infected pages are marked as dangerous in the search results, and when visiting them, there will be a notification about this. For maximum protection, we recommend that you combine all 4 methods. This approach will allow you to quickly find attempts to inject unwanted scripts and viruses that have already hit, saving money, effort and time. In the meantime, let’s look at the most famous services and tools for scanning sites and files for viruses.

Services that perform code verification. Compared to content analysis, a more profound verification method. With its help, it is possible to arrange a hunt for viruses of absolutely all elements of the site.
