Today's pests require more than what most will install (Norton or other suite.)
Try these (found with google.com)
Both free and I eject all they find.
Ever since my fiance got home and began using her laptop VIA wireless connection our internet connectivity is choppy and pages load slower than before. I thought it might just be her computer until I went upstairs to my laptop (which I also use wireless) and mine was a little slow too. We have one router connected to her desktop and cable modem and then of course my laptop and her laptop run wireless off of that. It seems that when she and I are on our respective laptops accessing the wireless connection our internet amongst other applications are a bit choppy. Any solution for this? She shut down her laptop and I went upstairs to get on mine and it was running beautifully again. Thanks for any help on this.
