Started with Norton way back in the 90's, used that exclusively up to 2000, then swapped to Mcafee for a few years, then in 2005 got accepted to test Windows Live One Care, at the time online game friend she was like go ahead test it, you may do good testing it
So Removed Mcafee, and installed WIndows Live One Care, And boy did i get infected while testing that program
One made some mistakes i'm sure while testing it, but have learned since then--had the shop rebuild the entire system, had major rootkit, bios virus, and who knows what else wrong back then, Then after that stopped using Windows Live One Care, and transition to Avast Free which i used on all household systems up til March 2019, trying Windows Defender now in Windows 10 Pro, so far no problems, but very very careful unlike i was in 2005
