Vircom, Inc. has released preliminary results from a public survey which will reveal what kind of protection measures are being employed by users to prevent spam and forms of cyber crime such as phishing. The email security leader has published preliminary results of the survey, which is already revealing a number of threats to the security of users. Forty-five percent of those who responded said that they share information such as their address book on social networks like Facebook and Twitter. An even larger number of respondents revealed that they do use unsecured public WiFi hotspots to get online. In addition, a high number do not check their email headers to ensure that bank emails they receive are legitimate, and many will read spam emails, click false links and download attachments.
