ANSWER: Definition source Wikipedia http://www.wikipedia.org/. Adware is software with Ad functions bundled in a program Spyware is computer software that is installed surreptitiously on a personal computer to intercept or take partial control over the user’s interaction with the computer, without the user’s informed consent. Malware is Malicious software installed on your computer A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. However, the term “virus” is commonly used, albeit erroneously, to refer to many different types of malware programs. Two of the best rated (in detection / removal) Antivirus prorams you can buy is Kapersky and Nod32. 39.99 (nod32 will NOT slow down your computer)
The Top Rated Free Antivirus Program researched from those who test Antivirus programs (av comparatives, virus.gr, and other reviews including this video review) http://www.youtube.com/watch?v=KhXZo3dHulc is Avira Antivir. Today you are in just as much danger from Spyware I Recommend SuperAntiSpyware ( I used this to remove spyware and Trojans from a laptop that adaware would only detect but not get rid of ) It detected and removed everything J You can also Download and Run Advanced Windows Care Personal, this will tune up your system and show you what starts at bootup, and allow you to edit this. (I recommend you uncheck the Registry tab, but pay close attention to the Spyware, Security and startup tabs and see what is starting up and disable harmful These 3 free tools will help you keep your computer clean)

ANSWER: Right now AVG. Avast is okay as well as McAfee. Norton is not exactly the best, but they are the most popular due to publicity. Avast uses a lot of memory, so if you have enough use that. However, over all it would be AVG. You can research the product and see how well it does and how easy it is.)

Ed’s note: The free AVG version is pretty good for basic antivirus protection but it doesn’t protect you against the latest rootkit threats, phishing email scams, instant messaging and web surfing threats.

ANSWER: Personally, I prefer the Avast Antivirus. Out of the many products available, it puts one of the smallest drains on system resources (It slows you computer down the least). There is a free version available, and the only valuable feature it lacks is an option to schedule a recurring scan. It does not have a popup blocker, however, I don’t know of any antivirus programs that do. There are computer security packages that include both. I can reccomend that you either install something else to block popups. You can use a Yahoo or Google toolbar, both of those block popups. A better solution would be to use a browser that has a popup blocker built in, such as Firefox. Even the latest version of Internet Explorer has one built in. Just be sure it is turned on. If you are still getting popups, especially if you get them when you aren’t even browsing the web, you might have adware. Look at these products (All have free versions): Adaware, Spybot Search & Destroy and Microsoft Windows Defender.)
