How to identify a fake email

Experience and common sense are the first weapons to avoid these kinds of scams.
Careful reading of the email, in all its elements, is essential. Be wary of ZIP-formatted attachments and, if possible, DO NOT enable automatic macro execution. It is strongly discouraged to set up automatic execution of macros since simply opening Word and Excel files will see the immediate execution of macros without any prior alert.
In case you have been infected by a Banker, the advice from TG Soft's C.R.A.M. is to take appropriate security precautions even after the remediation of the system(s) involved, such as changing the most commonly used passwords on the Web. In case the workstation involved is used for home-banking transactions, an assessment with your credit institution is also recommended.

How to send suspicious emails for analysis as possible virus/malware/ransomware and/or Phishing attempts

Sending materials to the TG Soft's Anti-Malware Research Center for analysis, which is always free of charge, can be done safely in two ways:

Any suspect email can be sent directly by the recipient's e-mail, to the following mail lite@virit.com,choosing as sending mode "Forward as Attachment" and inserting in the subject section "Possible phishing page to verify" rather than "Possible Malware to verify";
Save the e-mail to be sent to TG Soft's C.R.A.M. for analysis as an external file to the e-mail program used. The resulting file must be sent by uploading it from the page Send Suspicious Files (http://www.tgsoft.it/italy/file_sospetti.asp). Obviously if you want a feedback on the analysis of the data submitted, you have to indicate an e-mail address and a brief description of the reason for the submission (for example: possiible / probable phishing; possible / probable malware or other).

We give you these suggestions to help avoiding credential theft, viruses/malware or even worse next-generation Ransomware / Crypto-Malware.

Integrate your PC / SERVER protection with Vir.IT eXplorer Lite

If you are not yet using Vir.IT eXplorer PRO, it is advisable to install, Vir.IT eXplorer Lite -FREE Edition-.to supplement the antivirus in use to increase the security of your computers, PC and SERVER indifferently,

Vir.IT eXplorer Lite has the following special features:

freely usable in both private and corporate environments with Engine+Signature updates without time limitation;
Interoperable with any other AntiVirus, AntiSpyware, AntiMalware or Internet Security already present on PCs and SERVERs. We recommend to use it as a supplement to the AntiVirus already in use as it does not conflict or slow down the system but allows to significantly increase security in terms of identification and remediation of infected files;
It identifies and, in many cases, even removes most of the viruses/malware actually circulating or, alternatively, allows them to be sent to the C.R.A.M. Anti-Malware Research Center for further analysis to update Vir.It eXplorer PRO;
Through the Intrusion Detection technology, also made available in the Lite version of Vir.IT eXplorer, the software is able to report any new-generation viruses/malware that have set in automatically and proceed to send the reported files to TG Soft's C.R.A.M.
Proceed to download Vir.IT eXplorer Lite from the official distribution page of TG Soft's website.
