I've been a fan of F-Secure for years now. I discovered them when they helped discover and eliminate the Sony Root Kit and I've been a big promoter of them ever since.
The company makes a great security suite for Windows PCs and they also make a tremendous anti-virus program for the Mac OS. In fact, last year my friends & I on the Pride Institute Best of Class Technology Panel gave a Best of Class award to the company for their superior products. Not only does F-Secure protect your computer, it also doesn't bot it down with bloatware or make itself impossible to uninstall (although why you would want to is beyond me).
The company also does a nice job of communicating with their customers via email and also through a great blog that is full of info on how to keep your computer secure.
Recently, they notified me of an article they had posted on the blog about 5 ways to connect safely on vacation. Here are the 5 recommendations. If you'd like to head over to the blog for more info and the complete article, here is the link. I think you'll get tons of info from reading the blog.
