I am having a lot of difficulty with the link...it is asking to update Java, but when I do, I am getting bells and whistles and all kinds of warnings and errors...egads!
Never allow a website to "update Java/Adobe Reader/Flash" or whatever. If you get such a message, go to java.com or adobe.com and do the update from there. If you don't know what the author/owner site is, just Google the software name. The right site should be pretty obvious.
Or, go to majorgeeks.com, softpedia.com or techspot.com and look for the software to download. These sites (as of this moment) only download the software you have requested.
Other sites, like download.com, filehippo.com, tucows.com and many more, by default use a "download manager". All the "download manager" does is offer to install software you DID NOT request. If you blindly click "next", "next", "next" throught the installs, you end up with crapware and adware on your computer. You can use the sites in this second group, but ALWAYS read what you're agreeing to when you click "next" or "accept" buttons. Also, these sites usually have a "direct download" link somewhere on the page, much less prominently than the "DOWNLOAD NOW!" button that brings in the "download manager".
And, finally, sadly, even if you only download the installer for the software you want to install, IT may try to install things you don't want. Both Adobe (virus scan) and Java (toolbars) will install things you aren't be interested in (you already have a good anti-virus program installed, right?) if you just click through the install.
Finally, if you can't remember to do these things, PLEASE make a restore point before installing any software or updates. It's really easy though it may take a minute or two depending on the speed of your computer (but may save you hours if something bad happens.) Here's a
link to a video and text instructions on how to create a restore point. Microsoft claims a restore point is created each time you install software, but that is not the case.
If something bad happens and you need to restore to an earlier point in time,
here's what you do.
Note that Windows DOES create restore points automatically. The default is once a week though, so you may lose up to 6 days of updates to systems files if you rely on the automatic restore points.
