Step How to choose the best antivirus
How to choose the best antivirus. Nowadays it is practically impossible to do without anti-virus software . However, we often hear about what antivirus or maybe choose the best antivirus whether free or paid but don't know how to choose the best antivirus. In this article I'll explain how to choose the best antivirus.
Here is the step.
A virus, no matter how good and effective, never offer complete protection against all types of viruses for the present day and future. In fact, the antivirus software products are only designed to be human and therefore might also report false positives. There is grouped into four group or categories.
First.
It is based on the method of signatures.That can identify a potential virus through recognition of its structure which is why you need to keep the definitions, that the information on the structure of the virus, up to date, otherwise it is as if the virus there It was right.
Second.
Based on heuristic rules in practice, this type allows to detect viruses that are not yet contained in the archive of the definitions usually, this second technique is used together with the method of the signatures. This type of virus can search for parts of the source code of the program and compare them to those programs considered malicious.
Another method how to choose the best antivirus would be rather to verify the integrity of the program through its checksum. Example, when you download a program from the internet, often also referred to a specific string, such as MD5 or SHA-1, which serves to ensure the authenticity.
Third.
Type identifies a potential virus not according to the structure of the virus but rather according to its behavior. In this case, it is not necessary definitions nor the heuristic rules in place will use a collection of possible actions that are precisely the behavior of a given virus.
In this category there are also the virus that use the sandbox that in practice, allow you to run a program in a virtual environment by controlling what actions then this makes in a nutshell, if the program, when executed, does not have a harmful behavior can then be started normally.
Lastly.
Type of virus which is one of the most recent instead uses data mining algorithms and machine learning. In this case we try to determine whether the file is benign or not through the features that are extracted directly from the file itself.
Although the first type how to choose the best antivirus is the most widespread. In theory, the best antivirus would be just what is simultaneously using the greatest number of these techniques. However, that in addition to these types also spreading the virus cloud that are nothing more than anti-virus particularly light in terms of resources used because through the use of an internet connection, rely on control and analysis of suspicious files directly to the producer of anti about suspicious files. If you want, you analyze them through that VirusTotal is a free online service that allows you to scan a file with more than 46 antivirus engines simultaneously. Examples of these are cloud antivirus Panda Cloud Antivirus, eScan and Immunet.
But it is better for a fee or a free antivirus?
The paid versions, usually possible to identify new threats in advance of the free virus, also observed fewer false positives. In addition, the paid antivirus offer better care than the free version, do not have annoying ads and also integrate other essential programs such as anti-malware, anti-spyware, firewall, filter against malicious websites and parental control.
In a nutshell, if you do not have to protect many computers, the free antivirus should be enough because it does not renounce protection in itself but rather the extra function to make up for this lack it would be enough just a little more patience and install. I hope that explanation is clear about How to choose the best antivirus.
