Think before you download
Be careful what you download on your computer.
McAfee Internet Security is warning the public about what it calls Potentially Unwanted Programs, or PUPs.
There's a lot of free software and apps online that come with unwanted results.
Your browser may suddenly display a new home page or toolbar, or the software could even skew your internet search results.
These changes are often disclosed when downloading the software, but people typically miss it in the fine print.
The programs are not technically viruses, but often behave like a virus, and can include spyware.
McAfee warns these programs are usually difficult to get rid of. So make sure you think, before you download.
