VirusTotal: Online virus scan. VirusTotal: Online virus scan Installing VirusTotal Uploader
But it never hurts to be on the safe side.
There is such an online service VirusTotal(VirusTotal) is a free service that analyzes suspicious files and facilitates the quick detection of viruses, worms, Trojans and all types malware, detected by antiviruses. The results of file checks by the service do not depend on any one antivirus manufacturer, since the VirusTotal service uses several dozen antivirus systems, which allows us to make more reliable conclusions about the danger of a file, compared to any one product.
This allows you to identify false positives of any one antivirus, or, conversely, failures to detect new threats, perhaps already included by other manufacturers in their databases. Moreover, all anti-virus databases used by the service are constantly updated, and the scan results indicate the dates of the last updates of all databases.
A wonderful opportunity VirusTotal is to identify already verified files by hash. After downloading a file, the system calculates its hash and, if there are results of checking a file with a similar hash, it will immediately give them to the user, indicating all the details, including the date of verification. In this case, it is possible to repeat the check at the current moment, with current database updates.
In addition to the usual file upload using a web form, it is possible to send files for analysis using the VirusTotal Downloader program, or via email. To do this, create a new message with the recipient [email protected] , write SCAN in the "Subject" field. Attach a file for verification (the file should not exceed 20 MB, if the attached file is more than 10 MB, the system will not accept it). You will receive an email with the inspection report. The response time depends on the system load at the time of your request.
On the site you can see statistics on scans performed in real time, the number of files that were detected as infected among the total number of files, the top 10 infected files, the number of antivirus updates, the number of files to be scanned using VirusTotal and the latest viruses found.
Service capabilities:
.Free independent service
.Use of multiple antivirus systems
.Automatic update of virus databases in real time
.Detailed results for each antivirus
.Global statistics in real time
VirusTotal does not replace any antivirus software software, installed on a PC. ONLY CHECKS are performed (viruses are not destroyed) of individual files upon request. But more than 40 antiviruses at the same time.!!!

Check the file on VirusTotal
Scan the file for viruses in online service VirusTotal can be done in several ways:
- upload a file from your computer using a browser
- send a suspicious file to e-mail
- install a special bootloader from Virus Total
1. In the first case, use the form on the service website. Call Explorer (the "Browse" button or in some browsers "Select file"), specify required file and click the "Submit File" button. After some time, the duration of which depends on the connection speed and file size, you will see a page with information about the scanned file and the ability to go to a page with scan results for each antivirus program.
By the way, the updated service for online file checking VirusTotal, unfortunately, does not yet have support for the Russian language. However, everything is simple: upload the file and get the verification result. The maximum file size is 20 MB, scanning is carried out by as many as 43 anti-virus programs.
For the English version we do this:
- We go to the site by clicking the button above.
- Click Browse and select the desired file on your computer. It is better to download programs zipped. Maximum size 20MB.
- Then click on the button- Send file.
The VirusTotal service provides a function for identifying already scanned files by hash. After downloading a file, the system calculates its hash and checks for the presence of a file with the same hash. If such a file has already been analyzed, the service will give you the results of its verification, indicating all the details, including the date of verification. Pay attention to the date!
If the last check was a long time ago, it makes sense to double-check the file again. This is generally preferable, because Every day new viruses appear and anti-virus databases are updated. To re-check a file for viruses in the VirusTotal online service, click on the button Repeat analysis now. For the English version: click on the button Reanalyse The progress of the scan is displayed in real time and shows the result of each antivirus scan.
A file scan will begin, the results of which will be displayed in the table below.
When everything is scanned completely, we look at the result. Here is an example (see photo).
What do we see?
Result: 0 viruses!
Not a single antivirus out of 43 detected anything suspicious!
You can safely use this file. If you have tested the program, then install it on your computer.
And here is another example of file analysis (done a long time ago, when the VirusTotal panel was in Russian):
4 pieces of some kind of rubbish were found here.
In the column Result- name of the virus.
Now it's up to you to decide whether to run this program or not...
Check link or site
After a complete scan, a security report will appear.
As a result, we see 0.Clean site!
Although the detection rate is provided by the use of several antivirus programs, these results DO NOT GUARANTEE that the file is harmless!!!
2. Second option- sending files directly by e-mail. To do this, you need to send to the service address [email protected] a letter with an attached file that needs to be analyzed. In the Subject field of your message, indicate SCAN. The size of the file being checked should not exceed 20 MB; if the file is larger than the established limit, the system will not accept it. After some time, you will receive an email with detailed test results. The response speed depends on the service load at the time of sending your request.
3. Third option- to check a file for viruses in the Virus Total online service, you can use the special Virustotal Uploader 2.0 utility, which you need to download and install on your computer. After its installation, the item will be added to the operating system context menu VirusTotal. This command allows you to directly upload files from your computer to the Virustotal service for anti-virus scanning. In this case, the computer must be connected to the Internet.
The report results in this case are displayed in the browser window.
The main program window looks like this:
In the upper area, you can load the source of a process to check. Below is the “Select file(s) and upload” button, by clicking on which you can upload several files at once. The size of each should not be more than 20 MB, and the number should not exceed 5.
Even lower (in the main window) there is a function for checking a file using a link. When you enter the link, a window appears with 3 options:
1) The file is downloaded to the computer, uploaded from the computer to the server, without being saved in the system.
2) The file is downloaded and saved to a temporary folder, then uploaded to the server for verification.
3) The file is downloaded and saved to the specified folder, after which it is uploaded to a remote server for verification.
If the hash of the sent file matches the hash from the server database, the program displays the following window:

And with Virus Total you can immediately check against all popular antiviruses.
Online file check Virus Total
So let's see what this looks like in practice. Go to the site virustotal.com
The site is easy to use and supports the Russian language. Here we can specify a file on the computer’s hard drive, or go to another URL tab to check the link to the archive or installer. We'll talk about this a little below.
The service has a limitation: it checks files with a volume no more than 128 MB. Please take this option into account.
Click on the button “ Choose File", then indicate the desired file, archive, etc. And click on “ Check" The service will download your file and then scan it with all possible antiviruses.
(During the test of loading the installer in , for some reason the file did not load. Only this message hung for a long time until I closed it myself
After that, I opened another browser - performed the same steps and the file was successfully downloaded. Therefore, if you encounter a problem that the download does not start, change your browser.) This is so, a digression, additional information.
After the download has occurred, Virus Total will begin to analyze the file for the presence of Trojans, viruses, and malware. You will see the verification data in the report.
As you can see, we checked 59 antiviruses and not one suspected a virus. In this list you will see such popular brands of antivirus programs as Avira, Dr.Web, and many others.
Opposite each of them in the column “ Result"If no threats are detected, a green check mark will be given. If the scanning was unsuccessful, you will see a gray peephole.
On other tabs you can view information about the current file, leave a comment, and take part in a vote.
Checking the URL (link)
Now go to the next tab - URL. Sometimes we have to download files from sites that seem suspicious. In this case, we can use VirusTotal to scan the archive or file from the link that we want to download.
First, let’s copy the link from which we are going to download the data to our computer or laptop (right-click on the link and select “ Copy link address") and paste it into the field. Then press the familiar button “ Check».
Important!!! Always include the HTTP:// or HTTPS:// protocol at the beginning of the link. Without it, the service may not load data for verification.
Here the check has already passed through 64 link scanners. And they all showed that the site is clean and safe. To view file data, go to “ Go to analysis of the downloaded file».
Here we see a message stating that the file is safe and can be used. Therefore, you can safely download it from the provided link. Below is a list of all antiviruses and their results.
If you re-check a file or link, the VirusTotal service will remind you of this: when and whether threats were detected.
You can view the latest analysis or start a new scan.
VirusTotal program
For the convenience of users, the developers of the service have developed a program of the same name, which is installed on a computer, and you can analyze links and data at any time without going to the resource itself.

Then click on the button “ Get and upload" In both cases, a page will open in the browser with the results of the analysis.
Please remember that the Virus Total online service will not protect your device. It only checks your data. To protect your computer, install an antivirus; for the first time, .
And that's all for today. We got acquainted with a site that online checks a file or link simultaneously using 57 antiviruses. If you know of other similar services, share them in the comments. It will be very interesting to consider them. See you again and have a wonderful time of day.
Marriage is an agreement, the terms of which are reviewed and reaffirmed daily.
Every user has an antivirus installed on their computer. But situations arise when it is necessary to check a file or archive with an unknown extension. It turns out that the antivirus will not always be able to recognize the threat. What to do in such a situation? VirusTotal.com virus checking service will help.
What it is
VirusTotal is a free service that analyzes suspicious files and links for the presence of viruses, Trojans, and malicious software. Let's look at how to work with it.
What is it for?
Antivirus software developers are guided by their own classifications of malware. Therefore, during scanning, one antivirus will consider the file dangerous, but the other will not. VirusTotal uses several dozen antivirus systems, which will help you make more accurate conclusions about the danger of a file. The databases are constantly updated.
One antivirus will not be able to reliably detect a virus, especially if it has just been launched.
How does it work
The system scans with 70 anti-virus scanners and services. Analyzes URLs, heuristics, signatures, metadata. The scan result report is distributed together with the VirusTotlal society. Any user can comment and vote on whether the file is harmful. This helps other people to know whether it is potentially dangerous.

What to do if some antiviruses said that the file is clean, while others say it is infected? Go to the “Detailed Information” section. Perhaps he has already been checked, but under different names. Then we can assume that it contains malicious code. Look at the information in the “History” section.
The “Community” tab will help you decide. Perhaps other people have left their reviews about it. Based on a combination of factors, you will conclude whether it contains a threat or not.Conclusion
The online virus checking service virustotal.com analyzes files and URL links for the presence of malicious code. The service will provide Additional information about dangerous data that can harm your PC. I recommend using this service as an addition to the installed main antivirus.
Virus Total is one of the most popular services that allows you to check a file or URL for malware. Provides a 100% probability of detecting dangerous data, including a variety of viruses, Trojans and worms that pose a particular threat to any information located on your computer.
On the main page of the free website checking service, there are three tabs - “separate file, link and search”. To load the required object from the PC memory, just select it through the built-in file manager and click the “Check” button. If you need to check a link, copy the URL of interest from the address bar of your browser, then open the corresponding tab on VirusTotal, hover over the special input field, right-click on it and click “Paste” or use the keyboard shortcut Ctrl+V.
The virtual software works with all modern web browsers, including: Google Chrome, Mozilla Firefox, Internet Explorer, Opera and many others. Please note that the file being checked, of any format, must not be larger than 128 megabytes. After the real-time scan is completed, you will see a list with results from different antiviruses. VirusTotal com makes it possible to repeat the last analysis, you can view detailed statistics and be aware of all potentially dangerous objects found during diagnostics. In addition, in the upper right part of the interface there is a special tab with ratings of files and links. Thus, each user can check for viruses online and leave their opinion on whether a file or website page is harmless or infected.
The service uses the following antiviruses: Dr.Web Link Scanner (Dr.Web), Emsisoft (Emsi Software GmbH), ESET, FortiGuard Web Filtering (Fortinet), FraudSense (FraudSense), G-Data (G Data), Google Safebrowsing (Google) , K7AntiVirus (K7 Computing), Kaspersky URL advisor (Kaspersky Lab), Malware Domain Blocklist (DNS-BH), AutoShun (RiskAnalytics), AVG, Avira Checkurl, urlQuery (urlQuery.net), VX Vault, ParetoLogic URL Clearing House (ParetoLogic ), Phishtank (OpenDNS), Quuttera, Qihoo 360, SpyEye Tracker (Abuse.ch), StopBadware, ThreatHive (The Malwarelab), Trend Micro Site Safety Center (Trend Micro), Wepawet (iseclab.org), Malwares.com (Saint Security), Netcraft (Netcraft), AegisLab WebGuard (AegisLab), Alexa (Amazon), AlienVault, Comodo Site Inspector (Comodo Group), CyberCrime (Xylitol), Dr.Web Link Scanner (Dr.Web), Wepawet (iseclab.org ), Yandex Safebrowsing (Yandex), ZDB Zeus, Zeus Tracker (Abuse.ch), Zvelo, C-SIRT (Cyscon SIRT), CLEAN MX, Antiy Labs, Kaspersky VirusDesk, K7 Computing (K7AntiVirus, K7GW), F-Prot, F-Secure, Baidu-International (Baidu), BitDefender, Bkav, TrendMicro, TrendMicro-HouseCall and so on.
Recently, many antivirus software have become interested in cloud technologies. Either Microsoft, then Panda, and soon ESET will also introduce similar tools into corporate products. But “clouds” are not all that the Internet has to offer in the fight against unknown types of viruses. You can, of course, analyze processes, services and other files using specialized utilities, but there is a more varied method, ready to squeeze one single file in the grip of sixty antiviruses.
Now there is a great need for online scanning of suspicious files using antivirus solutions. There is only one problem - users are accustomed to the fact that some inconspicuous antivirus in the tray does everything for them, and sending each file for scanning is an ordinary case when the situation has completely gotten out of control.
One of the online checking tools has long been a service called VirusTotal. For example, you suspected a file from a working flash card was malicious, went to VirusTotal.com, added it (up to 32 MB), the system began checking. If it finds a similar scanned file, it will notify you of the result of the previous scan, and if a repeat scan is necessary, VirusTotal will begin scanning with 50+ antiviruses. The system checked my 14 MB file in less than 2 minutes, there are no problems with speed.
Another thing is that the service is more suitable for checking sites for malware rather than individual files, since it is incredibly rare to come across files that would be ignored by leading anti-virus solutions.
On the one hand, the advantage of the service is scanning with 50+ anti-virus databases at once, but who doesn’t allow you to download a couple of anti-virus scanners from leading laboratories ( and ) and run a search on a specific folder or file? I don't think they will ignore the infected file. It’s another matter when you don’t want to update utilities, but need to check the file with fresh databases.
For more comfortable work with the resource, there is the “VirusTotal Loader” utility. Unfortunately, there is no information about her on the official website, but she can perform very useful operations. When launched, the program displays a list of active processes on your system, from which you can select a suspicious one and send it for scanning to VirusTotal. The utility also allows you to select local files on the disk for scanning or specify a remote file URL.
conclusions
The VirusTotal service is very useful in cases where you do not use antiviruses at all, or you suspect that your antivirus has missed “malware” and want to check it with other antivirus solutions. This can be very useful in case of false positives, as well as when antiviruses “baptize” programs as malicious only because the developers of this antivirus have a competing solution and it is profitable for them to get rid of competitors in this way. You don’t have to look far for examples - AVG antivirus easily and naturally baptizes the Reg Organizer utility as “potentially dangerous”, while offering its product. VirusTotal will also help you check the site you want to visit for the presence of malicious scripts.
