How to check your computer for viruses online. 10 ways

The question of how to check your computer for viruses online is very popular among novice users. Before proposing methods of scanning, I recommend that you familiarize yourself with the following information about online scanning for viruses: the main thing to know is that it will NOT work to perform a full scan of all files on a computer somewhere on a website on the Internet, because then you would have to download all the contents of the PC or laptop to this site. But you can:

  • Check individual programs and other files for viruses completely online, uploaded them to special services.
  • Download special Antivirus utilities, which, although they are called “online scanners”, but work on your computer, and from the Internet use the anti-virus database for scanning (which can also be downloaded to the computer). As a rule, they do NOT conflict with already installed antiviruses.

In this manual, in detail about the various methods of online virus scanning of a computer with Windows 10, 8.1 and Windows 7 or SEPARATE programs and other files. I note that often the prerequisite for certain problems with the work of a computer or the Internet are NOT viruses, but malicious programs, which are ordinary antiviruses “do not see”. In this case, I recommend that you try special malware removal tools.

Trend Micro HouseCall. Online Computer Security Scanner

Trend Micro is a popular developer of antivirus products, little known to Russian-speaking users. Housecall is an online virus scanning utility from this developer, available for free download on the official website

After downloading Trend Micro HouseCall and accepting the license terms, all you have to do is click the Scan Now” to start scanning (Considering that the initial initialization process can take several minutes. the anti-virus database will be loaded, and the process is at 0 percent).

The scan will analyze startup programs, running processes, other typical locations of viruses and other threats, and files on disks. Upon completion, you will receive a report on the found malicious elements with the ability to remove them.

Hybrid Analysis

The disadvantage of the two listed scanning methods is that they are limited to the only anti-virus that performs the scan. Virustotal does not have this disadvantage, but if you are interested in even more powerful online virus scanning tools, I recommend that you get acquainted with Hybrid Analysis.

At first glance, the service is not much different, but during the scan you can select a virtual machine on which your suspicious file will be launched and get very detailed and easy-to-learn reports in the analysis. Separate instructions for using the service: Online virus check in Hybrid Analysis.

Crowdinspect works differently from the other online virus scanners listed in this roundup. The program does not require installation on a computer, and after starting it opens a kind of task manager, which displays the processes running on the computer and the results of their scan using various tools, including the aforementioned Hybrid Analysis.

The utility is excellent and I recommend having it in your arsenal. A separate overview of the tool’s capabilities and where to download it. How to check Windows 10, 8.1 and Windows 7 processes for viruses in CrowdInspect.

Microsoft Safety Scanner

Microsoft has created its one-time scan service, the Microsoft Safety Scanner. The validity period of the product is ten days, after that you will have to download a fresh one, with corrected and supplemented databases.

There is also a newer tool called Malicious Software Removal Tool. Both services work and do a good job with their functions.


Another service that allows you to perform web scanning for the presence of malware, trojans. Many users are already familiar with Trend Micro products. The utility is available on the developer’s website.

After the launch, the download of various Special files is activated, then you need to accept the points of the English-language license and call the Scan Now button to start system testing.

Principle of operation

In fact, it is impossible to check the device without downloading the installer. Scanning is online, but the scanning program itself needs access to your files. So one part of the antivirus functions as a browser module, and the other as a small application. Let’s also get acquainted with a couple of “helpers” that support online verification without downloading.

There are times when everything has been scanned, but nothing dangerous was found, and the device still does not work correctly (there are ad blocks on websites, it is impossible to open a page, etc.), most likely, it is necessary to remove the malware from the device. Before you can check your computer for viruses online for free, you need to know some features:

  • You will have to download an application, and not a full-fledged program, but having a special directory or connection to the cloud storage where it is located. Another method is to drop a suspicious object for verification directly to the site;
  • Such downloadable programs most often DO NOT interfere with the installed full-fledged antivirus;
  • You should use only proven analysis methods, that is, take utilities directly from manufacturers. If the site contains third-party advertising, the resource is unsafe. Antivirus developers do NOT earn money from advertising, they just sell their products, so they WILL NOT post other people’s blocks on their own sites.

If everything is clear, you can start the process.


Perhaps, almost all users know this product. It allows you to effectively check the necessary materials for viruses. Its convenient service quickly analyzes specific objects. For this you need:

  • Select the “Review” item on the official resource;
  • Specify the path to the file that needs scanning;
  • Name on the “Check” key (Or Scan).

Works online efficiently and efficiently, no need to spend a lot of time.

We check your computer for viruses online quickly and for free

Unfortunately, not every user has an antivirus on their computer device. Someone is lazy, but someone simply does not consider it a necessity. If suddenly the equipment starts to slow down or advertising blocks appear in the browser, you can check your computer for viruses online. Today there are several services that allow you to quickly scan your PC at any convenient time. Consider the best antiviruses and their features.

Panda cloud cleaner

At first, Panda had a publicly available tool that runs directly in the browser. Currently, there is only a utility that loads its modules onto the computer (no need to be confused, it is not installed and does not affect other antiviruses). The principle of operation of Panda Cloud Cleaner is similar to the previous product: the anti-virus databases are loaded, and testing of the equipment for threats noted in THESE databases begins. After completion, a report on the “Finding” will be drawn up (when you click on the arrow, all the detailed information about specific elements and the possibility of their removal comes out).

It is worth remembering that the items that are located in the Unkonown Files and Cleaning Systems subsections do not always refer to viruses on the PC. The first item is used to store unknown files and strange for the program entries in the registry. The next one will be the possibility of clearing disk space from unnecessary objects. Experts advise using the portable version, because it does not need to be installed. Among the disadvantages of this tool, one can single out only the lack of Russian-language support.

  • Operational check (about half an hour)
  • Identification of common threats;
  • Highly efficient online cleaning.

Panda is also capable of “self-destructing” after it checks and disinfects files. So it will automatically delete, it will NOT leave anything behind.

Useful content:


This tool belongs to the Google corporation, it helps to check various objects from a PC, as well as various resources on the Internet for the presence of worms, Trojans and other infected software. It is located on the official website, you just need to select the file that needs scanning. You can also specify there a link to a page that arouses suspicion (there is a link below “Check URL”).
