Virus Protection software
Virus protection software, or antivirus software is used to scan a
computer from viruses which can be brought onto the computer through
attachments or downloads, as well as being ran in the background as the
internet is used. This includes scanning
for computer worms or Trojan horses. The more effective virus protection
software has extra protection included with it, where it protects the computer
from spyware or adware, which are received from the internet, usually as a
pop-up ad. The virus software will try to block these pop-up ads, but in cases
where one does open, the virus protection software tells the user to stop the
pop-up advert before it attacks the computer. Infected files are separated from
other files and the user is asked if the file should be deleted.
Virus protection software improves the
performance of the computer it works on due to it being able to detect threats
or viruses, then normally, a firewall will block them.
This means that the virus
protection software ensures there is a safe environment. When a system is virus
free, the effectiveness that the system runs at is as good as possible. The
virus protection software wouldn’t cause interference or cause a performance
decrease as it is only majorly prioritised if an issue is found, which should
then be removed.
The picture to the left is an example of Comodo
scanning a computer for possible threats. There are several examples of
antivirus software, including Comodo,
Norton, McAffe
and there is many more. Some cost more than others do, but this is generally if
the antivirus software is able to achieve more than others do, though, it is
better to get a more expensive one due to the better protection that is given.
