1.3 Prevention
When you work with your computer, and especially when you browse the Internet, please keep in my mind that no
antivirus system in the world can completely eliminate the risk of infiltrations and attacks. To provide maximum
protection and convenience, it is essential that you use your antivirus solution correctly and adhere to several useful
rules:
Update regularly
According to statistics from ESET Live Grid, thousands of new, unique infiltrations are created each day in order to
bypass existing security measures and bring profit to their authors – all at the expense of other users. The specialists at
the ESET Virus Lab analyze these threats on a daily basis and prepare and release updates in order to continually
improve the level of protection for our users. To ensure the maximum effectiveness of these updates it is important that
updates are configured properly on your system. For more information on how to configure updates, see the Update
setup chapter.
Download security patches
The authors of malicious software often exploit various system vulnerabilities in order to increase the effectiveness of
spreading malicious code. With this in mind, software companies watch closely for any vulnerabilities in their
applications to appear and release security updates to eliminate potential threats on a regular basis. It is important to
download these security updates as they are released. Microsoft Windows and web browsers such as Internet Explorer
are two examples of programs for which security updates are released on a regular schedule.
Back up important data
Malware writers usually do not care about users’ needs, and the activity of malicious programs often leads to total
malfunction of an operating system and the loss of of important data. It is important to regularly back up your
important and sensitive data to an external source such as a DVD or external hard drive. This will make it far easier and
faster to recover your data in the event of system failure.
Regularly scan your computer for viruses
Detection of more known and unknown viruses, worms, trojans and rootkits are handled by the Real-time file system
protection module. This means that every time you access or open a file, it is scanned for a malware activity. We
recommend that you run a full Computer scan at least once a month because malware signatures may vary and the
virus signature database updates itself each day.
