GROOVESHARK – MALWARE WARNING
Be careful out there!
I went to Grooveshark tonight to listen to some music. (Here’s what I wrote about Grooveshark recently. For obvious reasons, I’m not going to link directly to the site tonight.)
Within a few seconds, the Internet Explorer window vanished and was replaced by a typical malware window claiming that my computer was infected with terrible diseases.
The malware came from a poisoned advertisement. Web sites that display advertising don’t put the ads there individually. Instead, they sign up with an ad network that’s responsible for supplying the ads to fill a space […] continued

CONFIDENTIAL FOLDERS IN SMALL BUSINESS NETWORKS
Here’s a procedure for people working in a very small business that don’t want to call me for every routine task.
Very small businesses frequently have a single folder for all company or firm files. It’s almost always mapped to a drive letter, so everyone stores all work files in the “N:\” drive or the “P:\” drive. Everyone has full permission to add, edit, and delete files and folders in the COMPANY or FIRMDOCS folder. There are subfolders for each client or project, so things get a little cluttered and messy after a while, but it works well […] continued

MORE HACKING ATTACKS
The Wall Street Journal reports today: “Hackers in Europe and China successfully broke into computers at nearly 2,500 companies and government agencies over the last 18 months in a coordinated global attack that exposed vast amounts of personal and corporate secrets to theft, according to a computer-security company that discovered the breach.”
This is apparently not related to the attacks from China that caused Google to make noises last month about closing its operations in that country. In fact, the New York Times calmly notes that this is a relatively small blip in the world of compromised […] continued

FIREFOX 3.6
Mozilla has released Firefox version 3.6, with increased security, faster display of web pages and Javascript, and some new features for add-ins and themes. Here’s a description of the new release and a video demonstrating some of the new features.
If you are running Firefox, you can get the new version by clicking on Help / Check for updates. Presumably it will soon be offered automatically when you launch Firefox.
Switching from IE is easy: start at this page and you’ll be given lots of information about what to expect. Firefox imports favorites and passwords from IE […] continued

UPDATES
I’ve prepared a list of computer safety tips for years. Over time, the advice to keep critical programs up to date has moved to the top spot on the list. You don’t have to spend all your time reading technology news but you do have to be able to identify which reminders are legitimate when they pop up from the system tray.
There’s a weird news story to illustrate why updates are important: the entire network of computers at the University of Exeter has been locked down and taken offline for days because a virus has […] continued

COMPUTER SAFETY 2010
Here’s an updated list of ways to be safe and secure with your computer.
Install updates from Microsoft promptly. Look in the lower right corner for the gold shield (WinXP) or update icon (Win7/Vista).
Install updates to Acrobat, Flash, Java, and Quicktime promptly. Each will alert you from the lower right corner.
- An easy and safe way to keep up with updates: visit Secunia Online Inspector once a month and follow its suggestions.
Install antivirus software and keep it up to date.
Know the name of your antivirus software. If you get a security

GOOGLE AND CHINA
The technical side of Google’s blowup in China is shaping up as an explosive story about technology and hacking. Keep an eye on this one!
On Tuesday Google announced that it would no longer comply with Chinese censorship demands and might cease operating in China altogether. As I understand it, Google has set up a separate search page that operates within China and censors some search results as requested by the Chinese government. I believe Google also cooperates with the government in blocking access to Google.com. Update: Apparently Google.com can be reached from Chinese computers but search results are […] continued

PREVIEW SPAM WITH EXCHANGE DEFENDER
Exchange Defender has a new tool for previewing quarantined messages.
Exchange Defender is the service used by many businesses to quarantine spam and scan incoming and outgoing mail for viruses before delivering mail to the company server. Exchange Defender sends a daily report listing all quarantined spam, as well as providing add-in software for Outlook and an online control panel for reviewing quarantined messages.
(Exchange Defender is well suited for any business running Small Business Server; almost all my clients with Microsoft Small Business Server rely on Exchange Defender. You need a partner to set it up for […] continued

ONLINE PASSWORDS AND LASTPASS
Previously:
Passwords: computer login
Passwords: e-mail
Passwords: Google Accounts & Windows Live ID
Password: password managers
LastPass will help you manage all of your online passwords. You should learn about it, install it, and use it every day. This is seriously good stuff.
LastPass is a free program that memorizes each password typed into a web site and automatically fills it in when you return to the same site. Once it’s up and running, the master password for LastPass is the only password you have to remember.
The feature that makes this genuinely exciting: your passwords […] continued

PASSWORD MANAGERS
Got a system yet?
Today I just want you to step back and look at the scope of the problem.
At the moment passwords are the only method of authentication in widespread use. There are lots of alternatives for more security or easier use – facial recognition, fingerprints, possession of a card (your debit card, for example), retinal scans, and who knows what else. At the moment, you are required to remember passwords and numbers in virtually every part of your life.
- Every online site that has individual knowledge of who you are – banks, social networking
