Computer Security - Top 10 Tips
computer viruses, computer worms, hackers, spamming, phishing, spyware, the
types and the quantity of malicious programs are on the rise every year.
Most computer users have to deal with these programs on a daily basis, so
what can you do to protect yourself from these attacks?
Install an antivirus + antispyware or all-in-one internet security
install internet security programs from reputable software developers. Do
not run free scan or free download unless you have done your research on
these products. Some free antivirus, antispyware programs may actually
install Trojan horses, adware or spyware in your computer.
Install security programs that provide active real time protection
antivirus or antispyware programs provide free scan to detect computer
viruses or spyware which have infected your computer. However, they cannot
provide active, real time protection. Some computer viruses are smart
enough to prohibit you from going to the free scan sites. They could
also cause damage to your computer before you run the free scan.
Keep your internet security programs up to date
internet security programs update their database frequently and allow you to
run automatic update either hourly or daily. Remember to renew your program
once the annual subscription has expired. An out of date program cannot
protect you from new threats that come out every day.
Install a firewall program
your firewall program to block any unsolicited inbound or outbound
communication. This can protect you from hacker attack. In addition, many
malicious programs run and spread via the internet connection without your
knowledge. Blocking unauthorized outbound requests can stop the spread of
Update your application programs and browser programs
programs have vulnerabilities which are subject to all sorts of malicious
attack. Software developers often locate these vulnerabilities and release
security patches to fix the problems. You should download these updates
regularly for maximum protection.
Be vigilant and selective about what you download to your computer
many free programs, free games and free music files available on the
internet. While many of them are harmless, some are malicious programs in
disguise or infected by computer viruses or spyware.
Be careful with email attachment
Do not open
unexpected email attachment even if it comes from people in your address
book. Computer viruses and worms can replicate and spread by themselves
using the address book of the victim. If your friendís computer is
infected, he may send you the computer virus or worm unknowingly. Internet
security programs can protect your computer by scanning the attachment
before you open it or save it in your computer.
Delete spam messages
messages are just unsolicited advertising, they are merely a nuisance. Some
spam messages contain links which land on bogus sites to steal your personal
information (phishing). They will use scare tactics to trick you to click on
the link. For example, they said they would close your PayPal account or
bank account unless you log in and update your personal information
following their link. The bogus sites may look very similar to the
legitimate PayPal or bank sites. Spam messages can also be used to spread
malicious programs such as computer viruses and spyware. When you receive
spam messages, do not click on the link or open any attachment, just delete
them. You can also install a spam filtering software or use the email
programs to block the sender.
Watch out for
computer virus hoaxes
receive email message warning you about a computer virus and ask you to forward
the message to as many people as possible. It may also ask you to search for
a certain file in your computer and delete it immediately. These warnings
are sometimes hoaxes, they try to deceive you to believe something is true
but in fact, it is not. The file you delete may be a legitimate file
required for some programs to run. Whenever you receive these messages, go
to the internet and search for the topic first. Do not delete any file or
forward the message unless you are certain that the warning is true.
Change your password frequently
Do not use
the same password for all sites. Change your password frequently using
complex words with characters and numbers. If you canít remember all the
passwords, use a password management software which can help you to fill in
the forms automatically.
