I started using Avast when Norton became bloatware about 5 years ago. I've since tried a couple of other products but keep coming back to Avast as it has NEVER caused a problem on any PC where I've installed it. Great product, I run the free version but really should pay for it!
I started using Avast several yrs ago after Norton,which came with my Dell,& AVG let Viruses onto my PC,I set-up my copy of Avast,so all shields w/expert settings were on HIGH & sandbox on ask,have had several instances of pages blocked,but just obeyed Avast & Xed them,no darn bugs get in my PC now. Thank U, 2 all the great people who built this A/V app, Travis.PS;I have also installed it on dozens of friends & family PC's & LT's
