A good consumer router (hardware firewall) only costs about $50 - $100 and can be picked up from your local computer store. If you only have one computer, it is pretty simple to setup yourself. If you have a LAN (local area network) of computers, you may want to hire a professional to help set you up.
And finally, don’t use a computer on the Internet without a good Pop-up Blocker. Part of Spyware are Pop-ups. A good Pop-up Blocker will work in conjunction with AntiSpyware to keep the Spyware at bay. Some Spyware will automatically keep launching new browser windows of websites they want you to visit. A Pop-Up Blocker will slow, or even stop, this from happening. Pop-ups can be so annoying. For every window you close, a few more open up. Again, this should be illegal! I like to use Zero Pop-up. It isn’t FREE, but unlike some Pop-up Blockers, it doesn’t have to be trained (meaning, whenever you get an unwanted pop-up, you tell it not to show it in the future, and eventually build a “black list” of unwanted pop-ups not to show). With Zero Pop-up, you can also block Messenger messages, banner ads, floating ads, and other things. I highly recommend it. You can download a FREE trial HERE...
To combat Spyware, you must incorporate an entire prevention scheme, made up of AntiSpyware programs, an AntiVirus program, a Hardware (not software) Firewall or Router, a good Pop-up Killer, and also be aware of where you can get Spyware and Viruses, and avoid these programs, emails, and websites. And it isn’t enough to install all of this, but also keep current on all updates and definitions, and run regular scans of your system (daily, if you can, if not, weekly).
