How to improve computer security?

Hi all,
Can anyone help me that what are the effective techniques and guidelines to improve computer security. Any help in this regard will be appreciated.

With Regards,

i suggest you use eset nod32, its very effective, easy to use and hard core in protecting your computer

At times computer security is used to tackle the problems such as corruption or thefts. Now these problems can cause different results. In general, we can say that specific requirements are required to be met for some of the most specific systems. Different approaches can be taken to gather the computer security information and hence one should b capable enough to detect the system requirements and then deal accordingly.
There are many ways to deal and improve the computer security and some of them can be easily incorporated. The first of them is to limit the computer access. This will reduce the access of other users and thus the security of the computer will increase as those who are granted access only they can use the computer. This will absolutely ensure the computer security information. One can also use hardware mechanism and create hard rules for the programs that are operating on the system. This will allow you to impose individual programs that can ensure the use of the information. One can even implement various strategies related to programming. This will let them resist the supervision and thus the computer programs will become more dependable.

Like the others said before, choose good antivirus software that meets your needs. Also, patch your system and internet browser when new updates are released. Also pay special attention to keeping up with patches for Sun Java, Adobe Flash, and Adobe Reader as these are commonly exploited software. You may also want to download a script blocker plug-in for your web browser. These script blockers ask for your permission before allowing javascript code to execute in your browser. This helps prevent malicious javascript code from attempting to install viruses on your system without your knowledge. Now, for those who really want to protect their system, they should look into installing a virtual PC. A virtual PC is pretty much a separate operating system that you run within your current operating system. The virtual PC uses a virtual hard drive and doesn't affect your physical hard drive in any way, so they are very useful if you want to test risky software or do anything on your computer that might cause damage to your operating system and files. Microsoft lets you set up virtual PCs for free if you have your own valid operating system disc. I will post a link later.

Windows 2000 is in a completely different safety league to Windows 95. Linux is even better. A joke in the computer industry goes "The software package said 'Requires Windows 95 or better', so I installed Linux".[/FONT]

If you have good knowledge of window registry then it would be very helpful to you...
you can more secure your PC...

1. Enable auto update for your system and softwares;
2. Install a nice anti-virus tool like AVG free
3. Disable unnecessary services via your control panel.

Have a nice day,

run windows as a user instead of admin
get vmware/free alternative
noscript

That is very important to do when you are running a server. When running a server, you should be using a restricted account and when you need admin power, you should run the program as an admin. This way, you have an extra line of defense if your server console session gets hijacked.

Here are few steps to protect your system with security

1.One of the best ways to improve your security is upgrade to the latest version of your operating system.

2.Unless you're a technical wizard able to spot viruses hiding inside files, you must run anti-virus protection software. You should also update the virus recognition data file regularly.

3.Unbelievably, many computers on the Internet have file sharing switched on.
This is wonderful news for hackers, since any computer with Internet file sharing activated offers its content freely to outsiders. It's a particular problem for computers built before 2000, as they often have file sharing switched on as a default. You can easily check and change the setting.

4.For the best Internet security, install a firewall to foil hackers. It's almost essential if you're running an "always on" connection through DSL or cable. Firewalls used to be clumsy things that took a degree in computing to set up, but the latest versions are wonderfully easy.

5.If you're looking for even greater security, you'll need to apply patches, which are small software add-ons designed to deal with specific security holes and other computer problems.

To protect your computer from viruses, don't open email from unknown sender and suspicious email that may pose as an email from a friend. Keep your anti-virus and firewall updated. Turn off auto run when inserting media devices and turn off remote desktop.

was just figuring out what would be the right anti virus to use to keep my PC safe.. got nice ideas from this threads.. thanks to all

You should ensure that the people who use your computer do not compromise its security by physically limiting access to your computer

I guess you should do some monitoring, tracking, and logging must be strictly enforced. If your data security and storage measures happen to be compromised, this is the only way to ensure that you can rectify the problem then regular testing is the next step.

For high computer security .in the computer it should be a license version anti virus . like McAfee ,Quickhill kaspersky ,norton .............................other wise the computer is not safe and the system should be affected any time your data can lose or the file will be get corrupted.............

Use Antivirus like Nod32 it take less resource and work fast keep it up to date dont download unnecessary files from any where on the net before checking thats keep your system clean and healthy

use a good antivirus and firewall and update the antivirus daily

I think we need to keep things simple. Keep your windows or operating system updated. At the same time, whatever antivirus you are using, you must keep its signatures and database updated too. Of course firewall should be "off".

A firewall (a good one) and an antivirus.
