Checklist: Protecting your business, your employees and your customers Do Unsubscribe from legitimate mailings that you no longer want to receive. When signing up to receive mail, verify what additional items you are opting into at the same time. De-select items you do not want to receive. Be selective about the Web sites where you register your email address. Avoid publishing your email address on the Internet. Consider alternate options – for ex-ample, use a separate address when signing up for mailing lists, get multiple addresses for multiple purposes, or look into disposable address services. Using directions provided by your mail administrators report missed spam if you have an option to do so. Delete all spam. Avoid clicking on suspicious links in email or IM messages as these may be links to spoofed websites. We suggest typing web addresses directly in to the browser rather than relying upon links within your messages. Always be sure that your operating system is up-to-date with the latest updates, and em-ploy a comprehensive security suite. Consider a reputable antispam solution to handle filtering across your entire organization such as Symantec Brightmail messaging security family of solutions. Keep up to date on recent spam trends by visiting the Symantec State of Spam site which is located here. Do Not Open unknown email attachments. These attachments could infect your computer. Reply to spam. Typically the sender’s email address is forged, and replying may only result in more spam. Fill out forms in messages that ask for personal or financial information or passwords. A reputable company is unlikely to ask for your personal details via email. When in doubt, contact the company in question via an independent, trusted mechanism, such as a veri-fied telephone number, or a known Internet address that you type into a new browser window (do not click or cut and paste from a link in the message). Buy products or services from spam messages. Open spam messages. Forward any virus warnings that you receive through email. These are often hoaxes.

The Disk Cleanup tool helps you free up space on your hard disk to improve the performance of your computer. The tool identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files. Why Cleanup Remove temporary Internet files.

Remove optional Windows components that you don’t use. Remove installed programs that you no longer use. Remove unused restore points and shadow copies from System Restore.

A firewall is an application which controls network traffic to and from a computer, permitting or denying communications based on a security policy. A personal firewall differs from a conventional firewall in terms of scale. Personal firewalls are typically designed for use by end-users. As a result, a personal firewall will usually protect only the computer on which it is installed. Many personal firewalls are able to control network traffic by prompting the user each time a connection is attempted and adapting security policy accordingly. Personal firewalls may also provide some level of intrusion detection, allowing the software to terminate or block connectivity where it suspects an intrusion is being attempted. ...

There are good reasons to be suspicious of e-mail. Some e-mail messages might be phishing scams, some might carry viruses. Images in spam e-mail might turn out to be pornographic, or to include Web beacons, which can be adapted to secretly send a message back to the sender. Follow these guidelines to help protect yourself when suspicious mail shows up in your Inbox. If you receive a phishing e-mail message, do not respond to it. Don’t open junk mail at all If an e-mail looks suspicious, don’t risk your personal information by responding to it. Delete junk e-mail messages without opening them. Sometimes even opening spam can alert spammers or put an unprotected computer at risk. Don’t reply to e-mail unless you’re certain that the message comes from a legitimate source. This includes not responding to messages that offer an option to “Remove me from your list.” Do not “unsubscribe” unless the mail is from a known or trusted sender. Use the junk mail tools in your e-mail program. For example, Windows Live Hotmail gives you the option to unsubscribe from mail that you previously had trusted or requested. This sends a notice back to the sender to have you removed from their list, while at the same time automatically adding the sender to your block list. Approach links in e-mail messages with caution Links in phishing e-mail messages often take you to phony sites that encourage you to transmit personal or financial information to con artists. Avoid clicking a link in an e-mail message unless you are sure of the real target address, or URL. ...

A few clues can help you spot fraudulent e-mail messages or links within them. What does a phishing e-mail look like? Phishing e-mail messages are designed to steal your identity.

They might appear to be from someone you know. Spear phishing is a targeted form of phishing in which an e-mail message might look like it comes from your employer, or from a colleague who might send an e-mail message to everyone in the company, such as the head of human resources or IT. They might ask you to make a phone call. Phone phishing scams direct you to call a customer support phone number. A person or an audio response unit waits to take your account number, personal identification number, password, or other valuable personal data. The phone phisher might claim that your account will be closed or other problems could occur if you don’t respond. They might include official-looking logos and other identifying information taken directly from legitimate Web sites, and they might include convincing details about your personal information that scammers found on your social networking pages. They might include links to spoofed Web sites where you are asked to enter personal information. Here is an example of what a phishing scam in an e-mail message might look like. ...

In computer security, a sandbox is a security mechanism for separating running programs. It is often used to execute untested code, or untrusted programs from unverified third-parties, suppliers and untrusted users. I Recommend Sandboxie for Daily use. The sandbox typically provides a tightly-controlled set of resources for guest programs to run in, such as scratch space on disk and memory. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. In this sense, sandboxes are a specific example of virtualization. ...
