When someone sends you an attachment in an email message, Do you analyze it to see if it has malicious code inside?
Many people do not carry out this task, being practically victims at that very moment of an infection that will later alter the proper functioning of their Windows operating system or any other one. To avoid this type of problems and discomfort when working with our favorite applications, we recommend use the antivirus you have installed on your computer, something of which we even recommend previously about one that is the most prestigious in the market. If you don't have it then try any of the following online antivirus suggestions, which only have the ability to scan a certain number of files from the cloud.
- 1. Whole virus
The prestige of this system is great, because, since it has belonged to Google since September 2012, the analysis of our files would be based primarily on the indexing results of its search engines.
For this same aspect, the analysis and revision of a file through this system is one of the fastest and most efficient tasks to perform. Virus Total relies on 46 different online antivirus and can scan files up to 32 MB; Furthermore, if you are going to download a file from the web, you can provide its URL to Virus Total, who will subsequently inform you if it is clean or infected with any malicious code.
Previously this system was known as FilterBit, although now you will find it with the suggested name. With this alternative you will have the possibility of analyzing a file on 42 online servers specialized in computer security.
It differs from the previous method because here, we could already use a file of up to 50 MB for its respective review. If after the analysis no virus, Trojan horse or similar malicious code has been found, the result is a congratulatory badge.
- 3. VirScan
This is another online antivirus scanner that is supported by 30 search engines specialized in computer security. The advantage that this alternative has over the previous ones is that here, you can upload several files (up to 20) simply and when you compress them into a Zip or RAR file, but with a maximum capacity of 20 MB.
As you can admire, there are a few advantages and disadvantages that this alternative offers us, being perhaps an additional one to mention, the fact that the system is a bit slow in its analysis compared to the previous alternatives.

With this alternative, you can review and analyze any file from your computer in the cloud with the servers of this service. The only problem is that it specializes only in trying to analyze the presence of malware and nothing else.
It relies on 20 online antivirus services, being quite effective since its analysis is carried out in real time. The maximum size of the file that you can analyze should not exceed 25 MB.
This alternative comes from the hand of an Italian company that specializes in computer software security. According to many users, this system works independently without relying on recognized online antivirus systems.
In any case, the effectiveness of the job is quite large even when its engines do not include such important brands as Norton, McAfee or Kaspersky.
- 6.chk4me
Although this service is not known to many, but mine can help you identify the presence of malware in any file you want. The opinion of computer specialists says that many of the creators of these malware generally develop their threats taking into account the recognized online antivirus services (which we mentioned above).
This means that malware may not be easily identified in these online services. That is the reason why we should go to this service, because with it we will have a better perspective of what the file under analysis may be containing. Supported by 26 antivirus engines, the inconvenience is that the file to be analyzed must not exceed 3 MB in size, being completely free only in the first five analyzes.
