Check computer for viruses online

Antivirus scanners can be used to search for and remove malware on your computer. Usually, you need to download an executable exe file for this to work, but some modern services allow you to perform online scanning as well.

Online virus scan without downloading an installer

Cloud antivirus scanners have the ability to scan your system without installation or registration. A small file or archive is scanned for viruses online without downloading any programs to your computer. However, this method does not completely check the computer for viruses.

Kaspersky VirusDesk

When scanning, VirusDesk uses SecurityNetwork signatures. The scanner searches for and identifies many known threats, providing the user with detailed information about the problems found. Instructions for working with the service:

1. Open the virusdesk.kaspersky.com page using your browser.

2. Select the file or link to check.

3. Click Check.

4. Wait for the scan to finish, which may take up to 2 minutes.

The file or link is scanned for viruses against anti-virus databases. At the end of the procedure, the site can send you a detailed scan report.

Important! There are no treatment options here. The main features of Kaspersky VirusDesk are scanning files and archives up to 50 megabytes in size (several files can be packed into an archive with a virus or infected password) and checking Internet links for potential threats.

Dr. Web

This online scanner scans files up to 10 megabytes using its antivirus databases. The tool cannot be called a complete solution for checking an entire computer for viruses, but it is perfect for spot scanning. This is how you can use Dr. Web Online:

2. Load the object to be examined using the "Select file" button.

3. Click "Check", and wait for the scan to finish.

Based on the results, Dr. Web Online provides the user with a complete report. If necessary, you can contact their support service.

3. Wait while the system analyses the file.

Once complete, you can view the verification details and share them with the security community if you wish.
