Update Your Operating System
– Computer security
issues are usually centered around flaws in the operating
system. As these flaws are discovered, software vendors
release patches to correct the vulnerabilities. Make sure
Windows updates are set to download and install automatically on your system.
Install and Update Antivirus Software
–
While
installing anti-virus software is one of the easiest and
most effective ways to protect your computer, it has
some limitations. Because it relies on definitions,
anti-virus software can only detect those viruses that
have definitions installed on your computer, so it is
very important to keep them up to date. You may still be
susceptible to viruses that circulate before the
anti-virus vendors add their code, so continue to take
other safety precautions as well.
Install and Update Spyware Detection Software
–
Spyware/malware has become an major threat to
computer security in recent years, and
many vendors
are now releasing packages that incorporate both
anti-virus and anti-spyware capabilities together.
However, if you decide to choose separate programs, we
recommend that you have only one of each installed on
your system to avoid potential conflicts. Anti-spyware
software varies widely in effectiveness and reliability,
so research your options in advance.
Use Your Computer's Firewall
– Modern versions of
Windows, as well as some antivirus security suites, come with a firewall
that
shields your computer or network from malicious or
unnecessary Internet traffic.
When installed and
configured properly, they provide another layer of
protection against
attacks on your system. Make sure that yours is
enabled.
Backup Your Data
– Protect
important data by copying it regularly to a CD or DVD,
external device, or other recovery system. Establishing
a backup and storage procedure can help minimize the
time required to recover data that is lost or damaged.
