How to use Gmail antivirus
gmail automatically Analyze the emails you receive. Once you receive an email in your inbox, Gmail will automatically run an antivirus on the attached files. Whether you receive them or send them, it is capable of detecting if there is any type of malicious file in the mail.
What happens when is a virus detected? Google indicates that if there is a virus in an email that you are about to send. This way you will prevent them from hacking your computer, for example. You will see an error message stating “A virus has been detected” and it will give you the option to send the same message or email but without including the attached file that it considers to be infected.
In the event that you receive a message with attachments infected by a virus, you will be notified. Gmail automatically scans received emails and sent emails. If it detects the known virus in an attachment sent to you, it will automatically reject the message and the sender will be informed. If it detects the virus in an email attachment that is already in your inbox, it will make it impossible to download that file. You will be able to read the email but not download the attachment that, according to Google, is infected with a virus. Unless you unlock it manually.
In case you want to open an email that Gmail blocks, we can do it. If someone has sent you an email with any type of file not allowed by Gmail, such as .apk files for applicationss, for example, you won’t be able to open it. In this case, there is a solution: from Google they explain that if you are sure that it is a secure file, you can ask the sender to upload it as a document or file to the Google Drive cloud. Once it is uploaded to a folder in Google Drive, you can attach it as a Drive file in an email to send it to you.
How to protect yourself and avoid viruses
Beyond taking advantage of the antivirus for Gmail, it is recommended that we use common sense so as not to get infected with any attachment… It is essential to be wary of offers, of raffles in which you have not participated, etc.
Do not open emails from strangers
Do not open emails with senders you do not know. In case there is an attachment, please do not download it on your mobile phone or computer. If you don’t know who the sender belongs to, it’s best to delete it or, under no circumstances, open a file.
Look at all the details.
Be wary of known senders. That is, if you receive an email from Netflix with attachments, first confirm that it claims to be who it is and that it is not a scam with malware attachment or any type of file that can infect your computer or PC.
Use the spam option whenever you receive suspicious emails to prevent them from coming back to you from the same sender. By itself, Google already marks as spam emails that it deems to be unreliable.
Be careful giving your data
Do not register your email in any service or website that is not reliable because they could give your data to third parties and make it more likely that all kinds of emails with fraudulent content will arrive. In these cases, you can resort to temporary emails for this.
