List of resources

Checking via Yandex and Google

There is no check, but there is an autonomous site parser for malicious code that monitors the state of the resource when the robot crawls it. To use you need to have Yandex and Google Webmaster. How to register is not the topic of this article. In the office we find the “diagnostics” section and the “security and violations” sub-item.

If everything is in order, then the inscription will be as in the screenshot. In Google Webmaster you need to go to “Security Issues”. If everything is normal, then online service will write approval.

It is not possible to perform a check upon request; it occurs in automatic mode. Regularly log into the webmaster account of the Yandex and Google search engines.

Unknown online program with a huge arsenal with a large number of parameters. There is also a virus check, which is simple but worth listening to. Go in and fill out the domain field.
. In the right column are the rest of the free tools.

Virustotal: will run 65 antiviruses for free

Virus analysis from virustotal boils down to parsing on popular sites and displaying the results. Here is the official website and enter the domain.

The report does not contain numbers or symbols; it contains a table of popular anti-virus scanners with the result of the scan: safe – green, red – infected.

Out of 65 scanners, one level of infection was shown. Quterra we’ll talk about it below, the blog is clean. For me, the virus scanner from virustotal is the most democratic and gives you a choice. After reading the reviews, I came to the conclusion that if no more than three are fighting, then it’s fine, but if not, then we need to look for a worm.

Quuttera.com: checking your website for viruses online has become easier

Quterra.com offers to check the site for viruses online. There is a lot of information for your free reports, then what is given for a fee? Seriously, as a webmaster I was afraid of three mistakes with home page. It turned out to be unfamiliar plugins. Official address and according to the old scheme, name and check.

There will be a long check of the resource from head to toe, including all pages. Be patient, the detection results are truly encouraging. After the analysis, click “detailed report.” There are three active sections in the menu; the errors themselves and suspected viruses are located in the “scanned files analysis” section.

1. Tab section.
2. Malicious. I point to the autoptimize plugin file, which absorbs all the site styles, thereby speeding up loading.
3. Suspicious. Medium threat level. I found a threat in the author's comment.
4. Potential threats. I found it again with the autoptimize code.

To view threats, click on the required section and find suspicious file and the code itself.

• Link to a suspicious object.
• The “view code” link opens a pop-up window with a piece of code that does not meet security rules.

I concluded that autoptimize provides an opportunity for hacking, we need to look for an alternative.

Rescan Russian scanner

New online tool, address here, distinctive feature: in Russian and enough information. Check and start as standard.

After a few seconds, it will issue a report that the wpsovet has passed the test on all points. The service boasts of cooperation with major hosting providers, timeweb, hostland, fastvps and others, it’s difficult to check, but we’ll take their word for it.

Sucuri: surprised

Go to the address and insert the site data by clicking scan website.

All points are good except the last one, but how did he determine that WordPress was not updated to latest version, hid information about the engine version on the blog. I was surprised, but I didn’t think so. In the third point: absence secure connection SSL and https protocol.

Aw-snap: checking all pages

I’ve known aw-snap for a long time, I’ve moved more than once. Scans the source code and all pages for errors and viruses. The address is here, don't look at the outdated design and tabular layout. Enter your address and view the report.

I see that the main errors are in the CSS, more precisely in the use of the display:none property, which hides the content from the visitor. I can’t fix this bug; it’s built on this technique of hiding elements under different conditions.

Kaspersky: adding virus sites to the database

You have found a virus and infected resource, you can enter it into a special Kaspersky online database. We go to this address, insert the domain of the resource being checked, simultaneously choosing whether it is clean or infected.

Depending on the choice, Kaspersky will check the resource and decide whether to blacklist it. I don’t quite understand how it works and how to find out the result of a virus scan.

Bottom line

Other popular antiviruses cannot check a website for viruses online, neither nod32, nor Avast, nor eset. They have.

I can summarize after checking with all antiviruses online:

• We need to look for a replacement for the autooptimize plugin.
• Regularly update the engine and plugins.
• You'll have to change the comments.

Goodbye to everyone, and in conclusion there is a video.

Among the many antiviruses, utilities and scanners, it is very easy to get lost and it is difficult to understand how exactly to check a site for viruses. Next we will talk about this in more detail.

1. Use online check:

• Sucuri - here you can check your website for viruses and malware for free. Quite a popular and accurate online scanner.
• Web Inspector from Comodo is a free online virus and malware scanner. The site describes the symptoms of site infection. You can treat your site for free if you find similar symptoms on your site.
• The free Ai-bolit service is one of the most popular solutions among technical support hosting. There is an online scanner and installer on Personal Computer. Quite reliable service.
• Virusdie is also distributed free of charge and you can check for viruses online. Very comfortably.
• VirusTotal is a good and very well-known resource around the world that checks whether your site is in the virus database of the most popular antiviruses and other similar services.

We recommend checking each of them to eliminate the possibility of a site being mistakenly identified as safe. For example, if you came to the site new virus, then at the time of verification not all services may have time to add it to their database.

2. Check via Google and Yandex

Who better than the most popular search engines should be able to search for viruses on websites. If your sites are not added to Google Webmaster Tools and Yandex-Webmaster, then do it urgently. Because In addition to checking for viruses, these services provide a lot of usefulness for website owners. There is no point in writing about how to use them, because... their interface changes approximately every six months.

Google has another service for checking a site for viruses GoogleSafeBrowsing. You just need to enter the name of your site in the appropriate window and click on the magnifying glass icon.

3. Check offline

Now let's check the site files directly on your computer. This check can identify most hacks that are not particularly active and may go undetected when using the online services we described above.

First, you need to download the site files to your computer.

Important! Do not run any site files or edit them on your computer. Otherwise, your computer may also be infected with site viruses.

1. Al-Bolit is a very popular tool. Since it can be used offline by installing it on your computer, we couldn’t help but add this scanner to the review.
2. ClamAV- free antivirus, suitable for any OS: Linux, BSD and Windows. You can install it on your computer and “run” the files. Virus databases are updated every 4 hours.

Important! Make sure that there is no conflict between the antivirus for the site and your antivirus for the computer (if you have one). In theory, everything should be fine, but if not, be sure to write to us about it.

When removing malicious code, do not think that you have cured the site. Yes, you restored the site, but the “hole” through which it was hacked remains, and 99%, that after a short time, the hack will happen again. Therefore, we have prepared tips for you on how to treat an infected site and how to improve site security.

The tool is designed to online check websites for unwanted software and other security threats. With its help, you can quickly check whether a site is under sanctions of the Yandex search engine, which does not allow it to occupy high positions in the search results.

How are sites checked for viruses?

The tool uses the Yandex API to identify malicious content on site pages. When crawling page URLs (indexing), Yandex robots carefully analyze the contents of each page and, having detected a virus on them, add this information to the index database. Search system marks the resource as dangerous in its search results and browser.

At the end of 2016, Yandex knows about 370 thousand dangerous pages (not counting Google, Rambler, Yahoo, etc.) that contain viruses, and this list is updated daily. During the day, Yandex browser users download 1.1 million files using a computer, of which 42 thousand are recognized by the Protect technology as dangerous.

The presence of viruses on a website has a very negative impact on its positions and is an important ranking factor. This is due to the fact that Yandex tries to guarantee the security of its issuance. Sites that distribute malicious codes and services will be marked as dangerous.

Types of threats that are guaranteed to be detected by scanning with this tool

What to do if a virus is detected on the site?

If you do not spread viruses of your own free will, then you need to cure the infected site; this can be done in two ways:

1. On one's own. To do this, you need to have a set of special skills and software that allow you to effectively analyze a site for the presence of web shells, malicious elements in templates, a database, or on the server as a whole.
2. With the help of experts. To do this, trust professional programmers from MegaIndex
   Specialists will scan the resource for vulnerabilities, “clean” the code from viruses, install an antivirus and clear the site’s reputation in search engines.

IN Lately The Internet has become the main habitat for viruses, since only there they can effectively spread on user computers. Gone are the days when systems were infected through disks or flash cards. With the increase in the amount of downloaded information, the number of infected computers has increased, as users perceive a threat from the Internet as something abstract and something that will not affect them.

Unfortunately, it is not. Neglecting basic security can jeopardize our data stored on hard drives. Infections of computers of large corporations became indicative ransomware virus, which extorted money for unlocking, and otherwise encrypted the data. Most contracted it due to simple carelessness.

Prevention of infection

First of all, you need to use antivirus programs. Most of them are capable filter traffic, in advance warning users about the danger lurking in the resource being opened. Even free versions can significantly enhance computer protection.

Secondly, you should go to browsers, in which it is built checking sites. They warn about the danger that awaits users on a particular site. One of these is Yandex browser. It has it built in by default plugin, which scans the site and limits access to openly malicious resources. If a user tries to access such a page, he will see a warning message and a prompt to close the tab.

Thirdly, try don't cross via suspicious links in in social networks. VKontakte itself warns that the site may be dangerous, so do not neglect the advice of the service. Most infections occur this way.

Using Google to check

This option is suitable for site owners who want to make sure that their creations will not harm users world wide web. If the site does not belong to you, then you will not be able to check it through search engines.

To begin, let's go to webmaster panel. It is located at google.com/webmasters/tools/home (you need to log in to your Google account). After that, click on the button “ Add resource" and enter the link to the site in the window. After that, click “ Add».

After this we will be required confirm rights to the site. To do this you need to place HTML template on the resource so that Google can identify us. We carry out all the steps from the instructions and click “ Confirm».

After confirmation, we can view all the information about our site. To do this, select the tab “ Security issues" If there are viruses on the page, the system will notify us about it. If not, we will see this picture.

Yandex for checking for viruses

By and large, in Yandex we repeat the same procedure as in Google:

Doctor Web and Kaspersky

For the most part, by checking a site through these two services you can be 97% sure that the site does not contain viruses. These laboratories have devoted years to developing antivirus programs, so there is no doubt about their competence. Let's start with Doctor Web.

Let's go to the official website vms.drweb.ru/online. In addition to checking for viruses, you can view an extensive selection information about viruses and their spread. The main part of the page is the address bar in the middle, which enter the link to the resource you are checking and click “ Check».

After a while we will get detailed description checks carried out, as well as a conclusion about the danger or safety of the page.

Job " Kaspersky"is built on the same principle. However, here we can also check files. Enter URL in the address bar and click check.

Unlike the previous service, we are not burdened with verification details, but are given the result immediately.

Other online services

In addition to those already discussed, there are other services for checking links:
