Sicurezza del computer

L’antivirus non fornisce sicurezza

Se avete montato un antivirus sul vostro computer non siete al sicuro.La minaccia dei virus non si combatte solo con l’antivirus. L’antivirus, semplificando, è un contenitore di tutti i virus scoperti nel mondo fino ad oggi; l’antivirus controlla i vostri file confrontandoli con il suo contenitore : quando vede che il file corrisponde ad uno di quelli immagazzinati vi segnala e blocca la minaccia.

E’ quindi chiaro che l’antivirus è efficace solo se trova un virus che era già stato segnalato da qualcun altro nel mondo. Non può fare niente per le nuove scoperte.

Ci sono inoltre dei virus che non si manifestano come tali se non dopo che l’utente, Voi, li avete attivati. Sono tutti quei virus che vi arrivano come allegati nelle email e che passano quindi la scansione dell’antivirus. Quando ci cliccate sopra, state lanciando un programma: il computer non può autonomamente decidere che quel programma, lanciato da voi, sia un programma malevolo; siete voi che comandate e quindi siete voi che infettate.

Consigli per una buona protezione del computer

  • Usate un servizio di email dotato di un sistema antispam e antivirus efficace. Diminuirà il numero di file che arrivano.
  • Pensate. Leggete la email, non cliccate sui link senza sapere cosa state facendo. Passate con il mouse sopra il link senza spingerlo : vedrete l’indirizzo al quale si collega e se l’indirizzo non centra niente con il soggetto che vi ha mandato la email… è un virus
  • Pensate. Leggete bene i pulsanti nei siti in cui navigate, non rispondete sempre “si” o “consento” senza aver riflettuto.
  • Usate Office 365. La maggior parte dei virus opera dentro i file di Word, Excel che vi mandano. Office 365 con le impostazioni di sicurezza attivate rende i virus non eseguibili.
  • Backup : fate un backup periodico dei vostri dati su un supporto vicino a voi (chiavette usb, un altro computer, sistemi nas)
  • Backup su Cloud : fate un backup periodico in un posto “lontano” dal vostro computer: il cloud è in questo caso, uno spazio su internet in cui memorizzare i vostri dati

Come vedete, tra i consigli, non abbiamo citato l’antivirus….. ma male non può certo fare.

Against cryptoviruses

The cryptovirus or ransomware can enter into our computer. No matter what we are trained to recognize suspicious emails. Sometimes we are tired, distracted and our level of attention is lowered. “They” are increasingly clever and good at making us make mistakes. We open attachments that we should not open. At this point, the damage is done. The virus encrypt a file at a time very quickly: we estimated that the virus is able to encrypt 10,000 files in 30 minutes. After encrypting files on your computer, it starts to encrypt the files of all network folders where able to enter: servers, your colleagues’s of computers. The damage can be incalculable. In our experience there is no anti-virus that can counter it. When the virus starts to encrypt your files, you do not notice anything until it’s too late, when everything is over: the virus manifests itself by changing the image of your desktop with a message: “All your files are encrypted . If you want to get them back you have to pay a ransom. ”

If we had realized the infection once it has started, we would have definitely lost something but we could limit the damage.

Based on these considerations, we have created a very simple program that checks the contents of your personal folders and alerts you via email if a virus is altering the content. The alert can only be sent to you or in conjunction with other email addresses. After receiving the message, turn off, without hesitation, the computer by pushing the power button: better to risk breaking the power supply, which can be replaced cheaply, rather than losing all your files.

The program is completely free and you can download it here: MECDATA DAWN OF JUSTICE. Our response to CryptoVirus.

Once installed, launch it. The program will ask you, the configuration. The only thing you need to enter is the list of email addresses that you will need to alert in case of infection.

At this point, the program starts and you can see the icon on the bar at the bottom. Through this icon you can enter again in the configuration to add or change email addresses.

For lovers of performance, This program is running 18 Mb of RAM and does not impact on the processor. It does not work on Windows XP.

We sincerely wish that there is useful, but if it were, in the last test, the scanner detected the infection only two minutes after the beginning of the same.

We suggest you install it. It does not solve, but improves.

Our additional tips

  • Do not open attachments to emails from strangers, especially if they are not email you expect.
  • Double check your emails from people you know
  • Do not disable the macro block of the products such as Microsoft Word or Excel
  • Back up files regularly
  • Backup up in cloud
  • Do not create file shares and folders with permissions to ‘Everyone’
  • Share folders only to users or groups strictly necessary
