3. ANTIVIRUS
Antivirus Software is a computer program
that identify and remove computer viruses,
and other malicious software like Worms and
Trojan from an infected computer.
Not only this, an antivirus software also
protects the computer from further virus
attacks.
(Malicious software (malware) is any software that gives partial to full control of your computer to do whatever the malware creator wants.
Malware can be a virus, worm,trojan,spyware,etc……)
5. Antivirus works using dictionary Approach.
The antivirus software examines each and
every file in a computer and examines its
content
with the virus definitions stored in its
virus dictionary.
6. This type of antivirus identifies suspicious
behavior of programs (like modification of
critical files/programs) and alerts the user
about the suspicious program or stop the
program from running.
If any program tries to write data on an
executable file, the antivirus software will flag
the program having a suspicious behavior,
means the suspected program will be marked
as a virus.
The advantage of this approach is that it can safeguard the
computer from unknown viruses.
The disadvantage is that it may create several false alerts too.
7. 1. Slowdown
It takes longer than normal for your operating system to boot up?
It is a known fact that malware has the tendency to slow down your operating system, your
Internet speed or the speed of your applications.
2. Pop-ups
One of the most annoying signs of malware is represented by the unwanted pop-up windows..
don’t click any suspicious pop-up windows
don’t answer to unexpected answers
8. 3. Suspicious Hard drive activity
Another warning sign of a potential malware infection on your system is the hard drive
activity. If you notice that your disk continues to have excessive activity even when you
don’t use it anymore and there is no present program or download running at that moment,
this could be the moment to check your system for malware.
4. New Browser home page, new toolbars
Your home page has been changed and you don’t know why? And you have a new toolbars
that you don’t installed.
This usually happens when you visit a website and you accidentally click an online link or
a pop-up window.
9. Antivirus software removes the virus code from
the file during disinfection, but this does not
always restore the file to its undamaged state.
So we need another tool to repair corrupted files.
File Repair is one of those tools.
Essentially what the program does is scan files
on your PC that are in some way damaged and
creates a new.
10. The difference between the free versions of antivirus software and the paid versions
are much like the differences between a trial version and a paid version of anything
else.
Free Antivirus
• Its limited (30 days or 60 days)
Paid Antivirus
• (You can use it for 1 or 2 year)
