Cursor jumps all over screen on a Macbook

If you think Macs don't get malware, you are sadly mistaken. There are plenty of free antivirus software on the Internet, so please find and download the security on your Mac computer as soon as possible. If you or your kids download music on a regular basis from nefarious sources, you are prime for infection. Or, if you do not have your own personal home network, you are leaving yourself wide open by connecting to open Internet connections in your neighborhood. Beware of network names like linksys or hpsetup. If there is no lock symbol beside the network name, that tells you it is an open network and anyone can connect to the network.

This morning as I was feeding my dogs, Danny and Daisy, my friend Lisa texted asking if she could call me about a computer problem. "Sure", I texted back, as I continued to feed my always seemingly starved ravenous pets.

Lisa complained about a problem with her Macbook cursor jumping around, moving involuntarily, and windows randomly opening. I asked if she had antivirus installed on her computer, "No, I never installed one on the Mac". It goes without saying Lisa, along with everyone else I know, thought MacBooks immune from virus problems.

Wireless enabled and no internet connection

The following is a repost of an unusual problem encountered a few years ago while troubleshooting a friend's Windows Vista laptop:

I installed a free anti-virus software.  After the installation, I encountered one problem after another.  Windows Firewall connection turned off and became disabled.  I was unable to connect to the Internet even though my wireless connection was showing as enabled.  Internet Explorer was showing a "Page cannot be displayed" error.

I googled "wireless connection showing enabled and no Internet", as I had never before encountered that problem. A blog entitled, Repair and reset Windows Vista TCPIP Winsock Catalog Corruption popped up and described the situation. It was easy and solved the problem in five short steps.  Be sure to click on the link for an explanation as to what caused the Winsock corruption.  This fix could save you a lot of potential headache. Here is the Microsoft Knowledge Base article for  How to determine and to recover from Winsock2 corruption in Windows Server 2003, in Windows XP, and in Windows Vista.

How to prevent opening viral email attachments

1. You introduced several viruses on your pc during the past few months by opening e-mail attachments that you thought were safe.  You want to prevent this problem from happening again. What check box option in Folder Options should you clear to do this?

Hide Extensions for known file types should be unchecked. A file name specified as pics.html.exe will appear as pics.html to make the file appear as an html file when it is really an executable.
