CMOS setup
Booting Process
 1st process when we power on computer
 Checks all H/W and peripherals with a software

 Its important to maintain
continues time and date even
computer is shut down for years..
 In boot menu we can set time
 Press F10 to save and Exit.

13. Hard Drive (Magnetic Storage Device)

14. Operating System Installation
Process
 First download .iso file from respective
website from Internet..
 www.Microsoft.com/download/win_8.1
 www.linux.com
 Or simple Lets Google do its JOB…
 Now Burn that ISO image file to Disk or
Bootable Pen Drive
 For that we need tools…
Really I Don’t Think So…. Lets See
How..!

15. Select BOOT Device and Types
 UEFI for Windows
 Legacy for Other operating System
 Turn off Security Boot Mode for
Linux and Other OS
 Now select Boot device after Saving
the changes.
 Suppose Select your PD

 IDM (internet download manager)
 Torrent downloader-Bit torrent or u Torrent
 Compiler for Programmers
 NOW Antivirus or Virus …next slide will define
that…………….

28.  A virus is a program that self-
replicates
 It is not data
 You can only catch a virus by
running a program
 Your computer runs all kinds of
programs
What is
Virus ?

29.  Virus
 Self-replicating
 Also called a worm
 Trojan Horse
 A program which appears to
be valuable but has an
unexpected consequence
Basic Virus Terminology
 The four most common virus infections
come from:
 File – A virus type that infects existing
files on the computer
(~40%)
 Macro – A virus that runs as a macro in
a host application such
as the MS Office applications (~35%)
 VBScript – A virus that uses Windows
Visual Basic Script
functionality (~10%)
 Internet Worm – A virus that is
primarily characterized
by it’s replication across the Internet
(~5%)

30.  Don’t open files that you are not expecting
 Many viruses automatically send files without the e-mail
account owner’s knowledge.
 Ask the sender to confirm unexpected files.
 Suspect messages that appear more than once in your Inbox
 You may receive the same e-mail from a virus repeatedly.
 Learn file extensions
 Your computer will display both an icon and a file extension
for files you receive. Open only file extensions you know
are safe.

31.  The following file types should never be
opened:
 .EXE
 .PIF
 .BAT
 .VBS
 .COM

32. Virus has been Detected !
 Clean
 Quarantine
 Shred
 Block
 Repair
SECURITY IS A MYTH
BUT IN THIS TECHNICAL ERA WE NEED PROTECTION OR
ASSISTANCE TO STAY PROTECTED SO
I WOULD SUGGEST
Windows Defender
Windows Security Essentials For below Win 7
And MacAfee Antivirus

33. Now How TO TAKE CARE…
 Don't treat it like a LAPPY … It’s a LAPTOP… !
 Keep it simple means don’t more than one software for
same purpose
 Scan it Regularly , Use it regularly
 Stay Updated and Keep Updated !
 And Finally Most IMPORTANT use SYSTEM TOOLS…as they
not to showcase

34. IMPORTANT System Tools : DISK CLEANUP

35. IMPORTANT System Tools :
Disk Defragmentation
