Tightening Windows PC Security with Free Software

By: Kelly Wright

PC securityis essential to everybody, and that is why prices for anti-virus and firewallsoftware tend to go high. But while enterprises have no other choice but to payfor data protection, regular home users can save off quite some money goingwith free PC security software.

Yes,preventing intrusions from the web, keeping files safe and ensuring the securetransactions of online banking can be done using free applications. And I meannot demo versions of software, not trial editions, but fully functional toolsthat many PC users either have never heard about or just don’t trust anythingthat goes with a 4-letter word.

Omittingthe technical details, each desktop computer nowadays should be protected by 3crucial components making the core of integrated threat prevention. Thesecomponents are: anti-virus, anti-spyware, and firewall.

Below I define in short what each of the components serves for.

  1. Antivirus application usually monitors the system memory (RAM) and controls operations with files (such as execution and opening). Whenever antivirus sees a behavioral pattern similar to virus activity, the software either stops the process, removes the threat, or informs the PC user of the detected virus infection. It is a common misconception that a good anti-virus is enough for safe online browsing and networking. Anti-virus is not enough. It doesn't matter what particular anti-virus you're using and what brand name stands behind it. Do not be misled by marketing promises. There are no 'best anti-virus software' simply because each PC and user's activity is different.
  2. Anti-spyware does even greater job by identifying a whole lot of potential threats and cleaning the infections. Whenever you're online, anti-spyware is on alert, ready to fight the spying tools. Spyware, unlike virus, acts behind the scene, often without causing any suspicion on part of a PC user. This kind of malware usually collects private data, reports it to home server, and creates the profile of your browsing activities. If you ever see unexpected pop-ups on desktop (when no browser is launched) or suspicious Windows messages, rest assured your PC is heavily infected by spyware. Most probably right now, when you're reading this, there's some nasty file inside your Windows system doing its job.
  3. Firewall is the sentinel and the guard. It controls the incoming and outgoing connection in network ports, and therefore it is a very powerful tool, vital for strong PC security. Since Windows XP, firewall is built into the system, but generally it is a good idea to opt for a third party solution.

?So settingup PC security on a budget involves usage of free anti-spyware, anti-virus andfirewall. Among free anti-virus solutions you can choose from AVG (by Czechsoftware company), Avast, Bit Defender, and some others. In the field of freeanti-spyware the choice is limited and there are anti-spyware tools which areactually bundled with commercial adware and spying modules. However, SpyBotSearch & Destroy is known to be a reliable solution, recommended by advancedusers.

If you are worried about keeping your data safe butdon't want spend too much money on commercial softwareArticle Search, I suggest that you lookat the option of setting PC security software which is free for personal.
