UPDATE YOUR BROWSER
According to Study: 637 million Google users surfing with insecure browser about 45% of Google users from January 2007 to June 2008 were using the most secure version of their browser (read the article above for more specifics). Google users not using the most secure version of their chosen browser, according to the article posted on ZDNet, basically boils down to people not having the latest major version of their browser. Although Google users with Firefox might comprise a minority of browser visits (as is the case Internet-wide), Firefox garnered the most users with up-to-date browsers.
UPDATE YOUR EMAIL PROGRAM
This whole post is not about updating your browser, but your computer in general. If you’ve read any of my posts in Technology > Computers > Email you’ve probably figured I’m somewhat of a Gmail freak. With Gmail as my main email application, I don’t have to worry so much about updating my Windows Live Mail and Thunderbird email programs. An up-to-date email program can help reduce spam and your chances of getting a virus, worm or malware via email.
UPDATE YOUR ANTI VIRUS
Yes, Yes, Yes! By all means keep your Anti Virus up-to-date. Most decent commercial Anti Virus programs are under $40 year. If you cannot find a paid Anti Virus program for your budget or you think its not worth paying for, then look for a free one. In this respect CNet’s Download.com can help you find reliable anti virus protection. Download.com is an excellent source to search for safe software to download for your computer including write ups and reviews.
