Security Tips to Protect Computers from Scams

It s near impossible to defend oneself from the kind of cyber attack that targeted Google Inc. and more than 30 other companies. But for the average computer user there are some common-sense steps that can help protect against viruses and other malicious computer code.

Install antivirus software. This can protect a computer against known malicious programs that could allow a hacker to steal personal information. Cyber criminals release thousands of new programs each day so it is important to update antivirus software.

Install software patches. Companies such as Microsoft Corp. and Adobe Systems Inc. are constantly issuing small updates to the Windows operating system and PDF reader in response to newly identified security bugs. Users should be sure to install these so-called patches.

Be suspicious. Consider attachments to emails, links on social-networking sites and files for download on Web sites guilty until proven innocent. These are the most common ways that criminals load malicious software onto a victim s computer.

Be vigilant in public. Sign out of your Gmail, Yahoo or Hotmail account when using a public computer and clear the Web browser s cache, cookies and history. Then close the browser.

People with access to sensitive information need to take extra precautions. They could be targeted by hacker who could takes steps，including sending malicious software in an email that appears to come from someone the victim knows. One way to guard against this is to encrypt important files. Also, businesses should deploy systems that track where sensitive information is being sent.

Use strong passwords. Create passwords that are a mix of numbers, letters and symbols. Don t use common words or personal information. Don t use the same password on multiple sites. Put one on your cellphone.
