Cloud services to check your computer

Unfortunately, you cannot check your computer for viruses using only one website opened in a browser. The fact is that for security reasons, web services do not have access to local files and programs on the PC.

But there are cloud antiviruses that can check the system without full installation and registration. To use one of them, you just need to download a small client and run it. After that, you can scan the entire computer or select partitions for a partial scan. In the process, the program will download the data it needs from the cloud. If viruses are found, the service will offer to remove them.

If you want to scan your computer with a cloud antivirus, try these services. All of them are products of well-known companies and work in a similar way - according to the scheme described above. Therefore, you can choose any of them.
