This article is based on my own user experience of free and paid Internet security software. The free software I used consists of Sygate firewall, AVG antivirus, Ad-Aware Free Edition, Spyware Doctor and SpyBot Search & Destroy in Windows XP operating system. The paid software in this case is Norton Internet Security 2009 in Windows Vista operating system.
You can protect your pc against different security threats prowling on the cyberspace by using free tools. The protection these programs offer is quite good. You may wonder why an earth to use so many spyware scanners? The answer to this question is simple. One scanner was not able to detect all threats, so it was appropriate to use several. All these spyware and virus detection and removal tools worked well and did their mission. Spyware Doctor is worth to mention, because it was the only program to detect register files infection. This phenomena reduced the performance of my computer remarkably, if it appeared.
When I bought a new computer, I decided to purchase Norton Internet Security 2009. The brand name was familiar to me previously, because as a Yahoo mail user I happened to know that Yahoo scans all attachments by using Norton Antivirus. So I thought it was a good choice. I have now used Norton Internet Security 2008 and 2009 over one year. I was able to upgrade to the new version for free. After I started to use the 2009 version, I noticed that it was more user friendly and faster than the 2008 version. Many times when I used the older version I wondered, why I have to do so many clicks in order to get my database updated. Now in this version of 2009 updating is easy and automatic as well as scanning.
The free tools I used before detected several times all kinds of spyware, adware and viruses on my computer. It seemed that there were certain “security holes” in this system through which malware was able to access into the computer. In addition, it took time to scan the computer by using several different scanners. Norton Internet Security 2009 provides more comprehensive protection against all kinds of security threats. It has antivirus, spyware protection, two-way firewall, intrusion prevention, operating system and application protection as well as web site authentication. Based on my experience, I can say that Norton Internet Security 2009 has provided a very good protection and it has kept my computer clean. It has not even detected any serious infections.
