Q Our Windows 7 computer is not functioning properly online. In an e-mail I received, I clicked a button to complete a survey and was taken to an Internet page to fill it out. But when I was done, I couldn't submit the survey.

In addition, when I try to load favorite Web pages, I sometimes get a blank page even though the Web address at the top of the page is correct. And on one occasion I logged into a website but found I wasn't able to do anything there.

Our security software says there are no viruses. What's wrong?



A The odd behavior of your PC suggests that it is infected with some malware, which you probably got by clicking on an e-mail link to complete a survey.

The survey was likely bogus, and the Web page you were taken to probably downloaded a virus or something of that ilk. It's possible the malware has made itself invisible to your security software.

The rule for e-mail is this: Never click on e-mail links unless you know and trust the sender. There's no guarantee that the Web page the link takes you to is legitimate, no matter how authentic it may look.

To bring your PC back to normal, go to malwarebytes.org and download the free version of the Malwarebytes program, which seems to find things that other security programs don't.

Q I live in St. Thomas in the U.S. Virgin Islands, and continue to have a problem with the Netflix and Blockbuster video services that provide movies and TV shows over the Internet.

When I try to view movies, I get a message that says the service is not available outside the U.S. It seems stupid that these companies would cut themselves out of a large market within the U.S. territories. Is there any way I can get around this annoying problem?



A Probably not. Netflix announced last month that its first streaming video service outside the U.S. would be in Canada only. I asked Netflix about service in St. Thomas, but haven't gotten a response. Blockbuster is in bankruptcy, so while it continues to offer downloadable rentals, it's hard to tell if the service will expand.

You can try another service, such as streaming TV shows from Hulu.com or the websites of the ABC, CBS and NBC TV networks. Or you could download movies from iTunes.

Note that streaming video works best when your Internet connection has a download speed of several million bits per second.
