We here at Tek-Min-Now recommend a few MUST HAVE Essential Security Programs that are all FREE of charge. If you use Windows XP and have noticed your computer not working as fast as when it was brand new then you need these applications. These ensure that you are sufficiently protected from hackers, viruses, spyware, trojans, password theft, key-loggers, over all security recommendations that will ensure you are not having anyone watching your every move while you are surfing the web, writing e-mails, or just chatting with friends.
Updated - I downloaded the new version of AVG 8.0 and was absolutely blown away, this is truly a great free solution, to complete internet security. I downloaded this application, did a complete update, and did a full security scan and I was happily surprised to see it found hundred of third-party cookies, that none of my other security software found. The only one that is up to par is the Google Spyware Doctor tool, that finds the same issues as this tool did. It looks at all of the cookies, and finds any third-party tracking or trojan cookies, and will remove them and store them in a vault for safety. Download this today!
Download this program and before doing the first Full Computer Scan, you should Update to the most recent virus definitions, and the most recent version of AVG to ensure that all new trojans, and virus definitions are available while doing a complete scan.
Once you have the newest version of AVG do a perform a Full Computer Scan. Also should setup automatic updates, and daily full computer scans, to ensure protection, as well as allowing for automatic protection to be on 24/7.
Zone Alarm is the best Free Firewall on the market today. Download and install this application and you have complete control over what applications are connecting to the internet at any time. Make sure that you have the program start when windows starts, and is always turned on to ensure 24/7 protection. When on if any program wants to connect a pop-up will appear asking you if you are sure that you want to allow this program to connect to the internet. You are free to deny access to any program. Great must have free firewall.
Spybot Search & Destroy is a great application to find Spyware that could be monitoring your every move, and reporting the web-sites you go to silently in the background of your computer, which can be sold for marketing purposes to companies. Download and install this program, do a full update, perform the system immunization, and then do a full computer scan. Once the scan is complete remove all of the problems found by this software. Keep your self safe from spyware. I would not recommend having this application running in the background as it can slow down your PC significantly, I would recommend performing weekly scans of your PC, but not to keep it on for 24/7 protection.
This is a GREAT utility, but can limit accessibility for some applications. This scans and cleans out any cookies that are automatically downloaded from web-browsing, and can potentially track your every move and send all the sites you visit to a third party companies to be sold. This program will scan and fix/remove all of these issues, plus it is FREE! The downside is when I have this program installed and have it on 24/7 (icon in the lower right corner) then one game I play called Continuum doesn't work, so I had to turn off 24/7 scanning, and restarted, then it worked.
