Q. A couple of my Facebook friends have posted a link to a program that says it can tell me who visits my profile. Is this real?

A. No, itís not. Most of the information about profile views and details like that are kept deep in Facebookís servers. There arenít programs readily available that can give you this information. One good way to spot a scam like this is that several of your friends posted it. Iím willing to bet all of those posts look the same and werenít in those friendís usual tone of voice. That means your friend clicked on the scam and the post was automatically added to their profile. If you see posts like these, itís best to just ignore them and not click them.

Q. Is the iPad Mini a better buy than the Nexus 7 or Kindle Fire HD? Which of these would you recommend?

A. I donít really think the iPad Mini is the best buy of this bunch. Itís really only the smartest buy if youíre already invested in Apple products. If you donít have a bunch of Apple apps already, the Nexus 7 and Fire HD are going to be a bit more powerful and youíll pay less. As for deciding between those two, that depends on what other services you have. If you have or want to sign up for Amazon Prime (www.komando.com/tips/index.aspx?id=10347), stick with the Fire HD. If you use Google Calendar or other Google Web apps, youíll find the most value with the Nexus 7. Want more details? Check out my tablet comparison chart at www.komando.com/charts/tablets.asp.

Q. All the text and images on my monitor suddenly got huge. How do I fix this?

A. The problem lies with your monitorís resolution. All monitors have an ideal resolution, and your monitor is using one that is too low. That means more pixels are going into each letter, which makes it look weird. To change it in Vista and 7, go to Start>>Control Panel>>Appearance and Personalization>>Adjust Screen Resolution. Click the drop-down list next to resolution to change it and click ďApply.Ē In XP, right-click the Desktop, select Properties and adjust the resolution slider. If you like what you see, click ďKeep.Ē You might have to try a few different resolutions before you find the best one for your monitor.

Q. I clicked a link in an email that had a .gov on the end of it. Now I think there might be a virus on my computer. Is this possible?

A. Definitely. Some scammers have a trick that makes a government website redirect to a malicious site. All they have to do is attach their link to a .gov address in a certain way. Then they can shorten the link of a sketchy looking URL to make it look like itís a .gov address. The best way to avoid this is to never click on a link in a sketchy email. If youíre not sure, manually visit the website in your browser and then use the siteís search to find the right information. You should also download a security program like Avast! (www.komando.com/downloads/category.aspx?id=1584) or AVG (www.komando.com/downloads/category.aspx?id=2519) to protect yourself.

Q. Iíve been using Internet Explorer 7 for years now with no trouble. Everyone tells me I should upgrade, but Iím not so sure. What do you think?

A. I definitely recommend you upgrade, either to Internet Explorer 9 (www.komando.com/downloads/category.aspx?id=9477), Firefox (www.komando.com/downloads/category.aspx?id=1581) or Chome (www.komando.com/downloads/category.aspx?id=5385). First, older browsers donít have the same features that newer browsers do. So youíre missing out on features like HTML 5, faster browsing and even better tab management. Plus, security has taken some major strides in the last few years. An older browser is an easy target for hackers. Internet Explorer 7 didnít have very good security measures to begin with. Some programmers have even stopped programming their sites to work in older browsers, so more sites will stop working correctly for you in the future.
