- Bitdefender QuickScan;
- Comodo Cloud Antivirus;
- ESET Online Scanner;
- Kaspersky Security Scan;
- Norton Security Scan;
- Panda Cloud Cleaner;
- Trend Micro HouseCall;
- Avira Internet Security.
It is worth noting that none of the utilities listed above is a full-fledged anti-virus program. As the name suggests, they are all completely free and are great for performing the scanning procedure.personal computer and system security checks.
It is also important to keep in mind that all remote antiviruses are not able to replace full-fledged antiviruses that can reliably protect your computer from various malicious software. The best option would be to use a combination of each type of utility.
ESET Online Scanner

Summarizing the information, it can be noted that this program perfectly performs the function of additional scanningsystem, but nevertheless, it must be combined with a full-fledged antivirus.
Avira antivirus

Here it is worth making a clarification that Avira Internet Security Suite is specifically considered. This software is quite popular not only because of the large number of functions that allow you to protect your computer from various malicious files and programs. It is also quite relevant due to the support of cloud scanning technology known as Protection Cloud.

- the program has a firewall that protects the device from phishing;
- user can use password manager;
- an additional, extremely useful and relevant feature today is the presence of a VPN client.
However, it should be borne in mind that the Avira Antivirus interface is extremely inconvenient and constantly imposes various additional software on the device owner.
Bitdefender QuickScan

A program that can be safely called "Real cloud antivirus". But its main disadvantage is the limited list of browsers with which it can interact. Their list looks like this:
- Internet Explorer;
- Mozilla Firefox;
- Google Chrome.
This is extremely inconvenient for many users. The downside is also the extremely small amount of functions performed. So the program can only:
- notify the user about the infection of the operating system;
- also gives only the name of a file or program that can harm your computer. The user needs to search for the location of the pest on their own.
The following positive qualities can be endured:
- high quality malware detection;
- phishing protection;
- very simple and user-friendly interface;

- the user can delete the detected pest without leaving the program;
- there is an opportunity to choose any of the three (quick, custom or full) levels of scanning the operating system.
As a disadvantage, it is worth noting the rather long period of the full verification procedure. So one of the tests showed that the utility completely checks the system in more than seven hours. Which is a very unsatisfactory indicator.
Quick system scan takes approximately 10 minutes.
Summarizing all the information, it can be noted that this program is quite innovative. But due to such important disadvantages as the length of the full scan, it is not the best choice.
Panda Cloud Cleaner

Cloud antivirus "Panda" is quite effective software among other representatives of this category. It is also installed on the computer as a separate application for the Windows operating system. One of the functions of the program is to automatically download the latest signatures before each start of the scanning procedure. Features and benefits include:

- user can remove detected threats without leaving theantivirus;
- in quick scan mode, the program completes the procedure in about ten minutes;
- full check is done faster than many of the programs of this type listed above and presented below - a little more than half an hour.

- list of malware and infected files;
- degree of system protection and availability of installed programs to perform this function;
- presence of other system security issues.
As negative points, one can also note the rather long time for a full scan and the traffic limit on the free version.
Comodo Cloud Antivirus
