ZoneAlarm Mailsafe

Company / developer:

ZoneAlarm's MailSafe provides virus protection for Microsoft Visual Basic scripts sent as e-mail attachments.

How MailSafe works
MailSafe protects your machine against viruses that can potentially arrive as e-mail attachments in the form of .VBS (Visual Basic script) files.

MailSafe is active by default; the option to enable or disable it can be found in the Security Panel. MailSafe works with mail clients that use POP3 and IMAP, the most common Internet e-mail protocols. It identifies .VBS scripts that arrive attached to your e-mails and prevents them from executing.

When an attachment is detected, ZoneAlarm quarantines it by changing the extension to .ZL and ends with either a letter or number. For example, a file called SERVER.VBS will be renamed SERVER.ZL1.

When you double-click on a quarantined file, ZoneAlarm asks whether or not you would like to open the attachment. At this point, you can choose to open the attachment, to delete the e-mail, or to check further on the validity of the e-mail and the attachment.

MailSafe does not automatically delete files attached to your e-mails and it is not a virus scanner. Rather than scanning and deleting viruses, it quarantines the attachment file and gives you the opportunity to keep the identified .VBS program from running. Visual Basic Script files can only cause damage when they are allowed to run on your machine.

MailSafe can cause a conflict with other mail-checking software. For this reason, if your e-mail system freezes or hangs or you run into a similar technical problem while you have MailSafe active, either disable MailSafe or disable other mail-checking or virus scanning software you have installed.

Opera browser

Opera

Opera is a web browser and Internet suite developed by the Opera Software company. Opera handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, IRC online chatting, downloading files via BitTorrent, and reading web feeds. Opera is offered free of charge for personal computers and mobile phones, but for other devices it is not free.

Features of Opera include tabbed browsing, page zooming, mouse gestures, and an integrated download manager. Its security features include built-in phishing and malware protection, strong encryption when browsing secure web sites, and the ability to easily delete private data such as cookies and browsing history by simply clicking a button.

Opera runs on a variety of personal computer operating systems, including Microsoft Windows, Mac OS X, Linux, FreeBSD, and Solaris. Though evaluations of Opera have been largely positive, Opera has captured only a fraction of the worldwide personal computer browser market. It is currently the fourth most widely used web browser for personal computers, behind Internet Explorer, Firefox, and Safari.

Opera has a stronger market share, however, on mobile devices such as mobile phones, smartphones, and personal digital assistants. Editions of Opera are available for devices using the Symbian and Windows Mobile operating systems, as well as Java ME-enabled devices. In fact, approximately 40 million mobile phones have shipped with Opera pre-installed. Furthermore, Opera is the only commercial web browser available for the Nintendo DS and Wii gaming systems. Some television set-top boxes use Opera as well, and Adobe licensed Opera technology for use in the Adobe Creative Suite.
