What does it mean to Recover your PC?
Clean Your Case: Required Items
• Several cans of compressed air
• Soft cleaning cloth
• Isopropyl alcohol
• Use the alcohol and cloth to clean the keyboard and
mouse. Get the cloth wet then clean the components.
You can use a mix of 50/50 water and alcohol, spray on
cloth and clean your monitor
• Use the can-o-air to clean the dust out of the fans,
power supply, and components inside the case
• Cans-o-air will run down when using it for awhile but
will replenish themselves, so have several cans available
when cleaning your case
Cleaning Supplies
There are a plethora of cleaning supplies on the market today. Below is an example of
what’s on the shelves at Office Depot, items ranging from compressed air to cleaning
Blowing out the dust bunnies
• Places to start
cleaning with your
can-o-air are indicated
with a red arrow.
• After you’ve cleaned
most of the dust out
you can then continue
spraying other parts
of the computer case
•Be careful not to turn
the can-o-air sideways
or upside down to
avoid liquid being
• Have several cans
available and as one
looses air, use another
until that one
• Do not touch any
Clean Inside: Keep These Up-To-Date
• Java
• Adobe Flash, Reader & Acrobat
• Your anti-virus software, including MS
Security Essentials, McAfee, Norton,
Symantec, AVG, Avira, ESET, etc
• Windows 7 and 8.1U Security P
• CCleaner & MalwareBytes
Java by Oracle
Java is a utility used and needed by some internet websites. You
should keep it up-do-date whenever you are prompted. Here are
examples of some of the icons to look for when an update is
You may all of a sudden
see a flashing yellow and
blue Microsoft shield on
your task bar. Click it and
if it says Java, then
You may also see a
flashing orange Java
icon in the lower right
corner of the screen.
Click it and proceed.
Java Do’s and Don’ts
When updating or installing Java, DON’T check the “Ask” toolbar
dialog box, as shown here:
DO uninstall old versions of Java via Add/Remove programs
Control Panel
Adobe Flash
What is Adobe® Flash® Player? It’s a browser plug-in that allows website
developers to create fancy introductions, navigation buttons, banners,
slideshows, moving text, and pretty much anything else you can think of.
If you get a pop-up that Adobe Flash needs updating, go ahead and proceed.
Be sure to uncheck the box that asks to install Chrome. It is not needed.
Adobe Reader or Acrobat
What is Adobe® Reader? It is a free application that allows you to
view, search and print PDF files.
The advanced form of Reader is called Adobe Acrobat. This is an
expensive program that allows you to create and edit .PDF
Be sure to uncheck the box that asks to install Chrome. It is not needed.
Know your Anti-Virus Software’s Name
Ask yourself one simple question….What is the name of my anti-virus
software? Is it McAfee? Norton? Microsoft Security Essentials?
If any of the below messages popped up on your screen, should you click on
it? The answer is a big fat NO!
Let’s review these pop-ups
Look at each of the examples. They are all similar, but not the same as,
Microsoft Security Essentials. The first one says Microsoft Antivirus—wrong
name! The second is Security Essentials 2011—close but again not right. And
the third is Antivirus XP 2008—is this anything close to the correct name of
your anti-virus software?
PC Tune-up Utilities
There are many so-called PC tune-up utilities on the market today, some are
legitimate and some are not. Do they work? Some may and some may not. If
a software promises to make your computer go faster, clean up viruses, and
generally makes promises too good to be true, then skip it. If a utility asks you
to buy it, then skip it.
Some fake or poorly written utilities include: TuneUp Utilities 2013, Presto
Tuneup, TuneUp Utilities 2012, PC Tuneup Maestro,, Comodo PC
The only utility you need is the free CCleaner. The company that makes this
software also makes an excellent defrag utility called Defraggler. Get them at
these URLs:
Searching for CCleaner
A word about doing a Google search for CCleaner. If at all possible, download the
utility from the company that makes it, Piriform. Below is an example of how some
companies can trick you into downloading the wrong thing. In this example, note the
small orange “Ad” symbol. Always avoid clicking on the first search item.
Searching for CCleaner
In this example, I am showing you how seemingly legitimate websites, such as, can
confuse you by directing your eyes to other useless malware and adware. Stop and read
everything before clicking. Out of all the “Download” links below, only one is for CCleaner.
Downloading & Installing CCleaner
Go to the CCleaner website and click the Download button, then click the
Download button on the next page.
Click the Save button and either save it to your hard drive or click the run
button to install it immediately.
Installing CCleaner
Installing CCleaner
Configuring CCleaner
After the installation is finished, click on
Options > Advanced and uncheck the
box as shown below
CCleaner: Using the Program
Click the Cleaner icon, then press the Run Cleaner button.
Results show how much crap was removed.
CCleaner: Using the Registry Cleaner
Click the Registry icon, then press the Scan for Issues button.
When the scan is finished, click Fix selected issues… button.
To download, go to, hover over the “For Home” tab,
click on Malwarebytes Anti-Malware, then click Get My Free Download Now
button. Choose to Run or Save to begin installation.
As you begin to install MalwareBytes, just click thru all of the default dialog boxes.
You will finally reach the final configuration dialog box as shown below. Be sure to
uncheck the box that says “Enable free trial….” otherwise Malwarebytes will send
you pop-ups encouraging you to buy the Professional version.
• After you’ve finished installing, the database will automatically begin to
update itself.
• After it is done, press the Scan Now button. The scan may take several
minutes or run much longer depending on how much data you have on your
hard drive
• Unlike past versions of MalwareBytes, the newest version does not give
you a choice of Quick Scan or Full Scan. It just scans.
If you have a clean computer, you’ll receive a dialog box and a summary. Close all
windows and exit the program.
If there is malware, you’ll receive a dialog box showing all of the infections. Click
the Quarantine All button and then Apply Actions. In some instances, it will ask you
to reboot. Afterwards, I like to run Malwarebytes a second time.

Phone Scam: Microsoft Tech Support
I am getting reports that people are still receiving
calls from “Microsoft Technical Support” but as you
know from this class, these calls are fake. If you
receive an unsolicited call, hang up immediately.
Remember these four points:
• Microsoft does not make unsolicited phone calls to help you fix your PC
• You have not won the “Microsoft Lottery”
• Microsoft does not request credit card info to validate your Windows PC
• Microsoft does not send unsolicited communication about security
For more information, go here and read more on this phone scam:
Search Virii: Conduit & Trovi aka Browser Redirect Virus
What it is: redirect, and the newest iteration called Trovi, is a
homepage hijacker which is installed by free software like browser toolbars and more.
When installing software, never click too fast through the dialog boxes. Read and
understand each box, and uncheck anything you don’t want or know what it is and
does. These redirect virii replace your default homepage on all your installed browsers-Chrome, Firefox or Internet Explorer. Search Conduit and Trovi are two of the worst and
prevalent problems PC owners face; they will monitor your search queries and display
all kinds of annoying advertisements. Once installed, it can be difficult to remove and
require multiple steps to bring your computer back to normal. If you want to attempt to
fix your computer, start at this website:
The Dreaded Fake Anti-Virus Virus
And the Worst of them All:
The Fake FBI Ransom Virus
The Fake FBI Ransom Virus
• First of all, don’t panic! You do not have the FBI spying you!
• This particular virus is called ransomware because they try to
extort money from you to fix the problem. Don’t fall for it!
• This can be a difficult virus to eliminate however, if you have
access to a clean computer, you can do a Google search and
find the multiple steps to rid your computer of the intrusion
• Essentially cleaning your computer involves starting in Safe
Mode—IF YOU CAN, that is. The last time I battled this, I
couldn’t even start in Safe Mode. This can be a very
destructive bug.
• The take away on this slide is that you can get this virus at any
time and to be sure you have a good backup of your data just
in case your computer needs to be restored from scratch.
• Have restore disks available or the disks that came with your
computer when you bought it.
Search Tip: Ignore the Ads and Faint Line!
Search Tip:
• My go-to search engine is I find it gives me
the best and truest results.
• I recently received an email about a seemingly impossible feat of
engineering called the Escherian Stairwell. I watched the video
then did a little Google searching. Let’s watch it now:
• Looked real, yes? But a Google search came up with several very
good resources that tell the truth. We’ve all heard of Snopes, but
did you know there are better resources than that? Namely:
• The point I’m making is a) Use the internet to help you make
better decisions and b) If something seems too good to be true, it
probably is. Google is your friend. Use it!
Uninstalling Software
Despite how careful you may be, sometimes software gets installed that you
don’t want or need. Let’s review how to uninstall software.
• Click the Start button > Control Panel >
• Windows 7: Programs and Features
• Windows 8: Uninstall a Program from the Programs category
• Windows Vista: Programs > Programs and Features
• Click the program you wish to install then click the Uninstall, Change,
Change/Remove button (depending on your Operating System)
Know how to Recover Your PC!
• Every computer manufacturer has a proprietary method of
restoring your computer back to factory default, that is, restore
your computer back to the first time you ever started it
• In the old days, computers came with Windows installation
recovery disks, but now most computers have either a built-in
method to restore Windows or require that you create recovery
disks yourself.
• If you don’t know how to recover your computer after a
catastrophic event, FIND OUT HOW—NOW!
• Keep in mind, when/if you have to recover your computer, it will
erase everything—documents, pictures, music AND programs—
from your computer. So be sure to have a good backup of all of
your data and that you have the original installation disks for
Know how to Recover Your PC!
• The program your computer manufacturer uses to restore your
computer back to factory default will probably have the word
Recovery or Restore in the program’s name, such as:
•Acer – Acer eRecovery
•ASUS – ASUS Recovery Partition
•Dell – Dell Factory Image Restore
•HP – HP PC System Recovery
•Sony – Sony Vaio Recovery Wizard
• If you didn’t create these disks when you bought your new
computer, do it now. In most instances, you will find the
recovery application in your Start menu under the name of
the manufacturer of your computer. Here is a good tutorial
on how to create the disks:
