Answer 1

it depends on what you mean by internet security.. antivirus,firewall,antispy

i know that norton slows my computer(2ghz) by 30% so i removed it

Answer 2

MINDDOCTOR did give a thorough answer, but you may also want to install AdAware and SpyBot. Read all about them on the following page. http://www.cybertopcops.com/reviews.php#av-as-reviews. In my experience with Grisoft, they certainly deliver software that is low on system resources. I suggest you also try out AVG Internet Security. http://www.cybertopcops.com/anti-virus.php

Answer 3

I found this site pretty helpful http://www.basicspywaretips.com/getridofspyware.html

Answer 4

In my spare time I test on my backup computer all antispyware/antivirus programs to see if the perform as claimed And especially to see which one have embedded trojans/adware either in their program or in the wizard installer used to guide you through the installation.

What is rate as 1-2-3-4-5 is not always the best. Especially when you can find free programs that are light years ahead in technology over the purchased.

In my computer I use the following free programs.

For antivirus you can only use one or you will have serious conflict with your system. You can use three or four antispyware without any conflict.

Avast in my opinion is the very best. Have you Avast for nine plus years and never had one virus. They are out of Prague.

http://www.avast.com This program is free and has one of the very best background scanner that will catch any virus in real time and destroyed the virus before it can enter you system.
Updates auto., two or three times per day. They will ask you for your email address so they can send you a free key that is good for one year. After one year you only have to request a new key.

Antispyware

http://www.ewido.net This company was out of Germany and has since been purchased by AVG. Now the name is AVG antispyware. Still the same program with excellent technolgoy. When you download the program it will come with all functions an if you don't purchase in thirty days they will just remove the background scanner and the auto updates. You will update on a manual basis. Scans all 195,000 objects in my system.

http://www.emsisoft.com This company is out of Austria. Almost the same as the new AVG. A2Squared free version download. They will ask you for you email address so they can send you a key that is good for life. You will get any new free version with the same key. Plus has rootkit protection and rogue dialer protection. (I have ADSL, but use for the added protection).

Firewall

http://www.zonealarm.com Excellent firewall free, if you download their free for home use version. You will get daily updates if any are due, plus if they come out with a new free version they will notify you via automatic and you just say yes, download the new version. The new version will remove the old version. Always best to do is clean install, instead of allowing the new version to copy the files of what you allowed or deny. You will just have to allow, or deny incoming/outgoing traffice again. If you check off remember on Zone Alarm, they will not ask you again if you want to allow or deny the same program.

For "zero day attacks", Attacks that hit before any security company has knowledge of the attack. I use a free software that is is excellent state of the art technology to identify any program that the behaivor is strange, like trying to download hidden files, etc. etc. Will get a pop up with indepth details, so you can decide for yourself if you want to allow or deny. Plus will block all malware. http://www.cyberhawk.com

If you want to spend money you can use what I use in my backup pc. http://www.filseclab.com Twister Trojan Antivirus. This program is used by the Government of China and you only pay a one time fee of $29.99 for live. Will include all new versions, auto, updates, an excellent support. Has a real great background scanner that really works, plus many other features that operate from the icon in the tray. Well worth the one time fee. Most other companies charge you an annual fee. China does not believe in the annual fee.

All of the above are low on resources. Plus they are free an in my personal opinion far superior in technology to any free or purchased other antispyware or antivirus programs.
