Computer Security includes threats such as viruses, identity theft, spyware, adware to name but a few. The latest statistics show that at least over 600 new viruses are created every month which makes keeping track of them really quite difficult. This "review" would cover three subtopics namely: The Internet, Spyware and Antivirus. Internet If you use your PC on the web, you need antivirus programs. The problem of system security is the number one problem in todays LAN and web engineering. As hackers use different means to crack the security systems it often happens to be impossible to resist and PC security system fail. Computer Security on the web is vital for home and business use as there are increasingly hostile environments when peoples surf the web. It is very important for users to be educated on the dangers they may face while on the web. Your PC connected to the www is similar to your house in many ways. People search on the internet for free PC security software which they dump into their machine and hope for the best. The web is a wonderful place. Anyone with an web connection can stay in touch with family and friends via email or via chat. Computer security is growing rapidly by the minute and the only one who has control over their files of information is the user. It is strongly suggested that people equip their system with an armed firewall for vital protection. An advice is to use "Microsoft Windows Update" to keep your system and Internet Explorer patched. Other advice could be to only conduct web transactions that have secured processing. Even if you have a PC connected to the web only to play the latest games or to send email to friends and family, your PC could be a target. Although confidentiality, integrity and authenticity are the most important things when it comes to computer security in general, for everyday web users, privacy is the most important one, because many people think that they have nothing to hide or the information they give doesn't seem sensitive when they register with an internet service/site. Spyware An avenue for Spyware to infect your PC is through popular p2p File Sharing software such as Kazaa or Strong DC++. Extreme spyware like Rootkits and other advanced spyware have fundamentally changed the playing field in todays PC security. While it may seem to be common sense, many of the most attacks have involved spyware and e-mail attachment worms. Often these packages come as "suites" including a firewall software and Spyware scanner. They scan and destroy spyware as it's found in the user's PC. Regardless of the type of spyware, it can slow your system to a crawl and needs to be removed from your PC. Spyware occurs when certain websites run application in the back ground of your system while gleaning information from it. There is now a bill in the US Congress to make Spyware illegal. Antispyware tools will greatly assist in protecting your privacy and restoring full PC functions that spyware may have taken over. In the web world it is vital for users to have a good spyware scan (a recommended and reliable one can be found in the Author Resource Box below) and removal tool because of the multitude of different spyware, adware, Trojans and other malware constantly looking to attack your system. Spyware can slow down your computer, and would have to be removed. There are tools available which include good free Spyware removal application among other security measures the user can take to protect the PC from malicious attack such as Viruses, Spyware and Adware. The recommended one is staed below. Spyware not only covertly runs in the background and steals private information of the user it is a potential security threat of which the extent of the damage cannot be determined. Antivirus With all of the marketing commotion that surrounds viruses, you should already have antivirus program on all of your system. Let me explain something, just because you have a antivirus software program on your PC you are not cured. Until recently could one install a firewall and an antivirus software and feel quite secure. Protection services could commonly include the ability of an administrator to monitor activity throughout the LAN as well as potentially block hazardous material on the web from being viewed by other people, the ability to manage automatic updates and what's more the ability to enquire about the status of antivirus program. These include firewall, spyware scanning software and antivirus applicatione. Everyone needs to have proper PC security measures in place to make sure they are consistently free from all these malicious software. Urgent action should be taken today.
