While I Tried Defender for a while on my Household systems, decided to stick with Avast Free in the end, as scan time is so much shorter if I run manual scans once in a while, possibly Avast Self Protection is a bit better than Defenders is.
Though I maybe safe with just using Defender, as I make sure to delete any emails that I even think maybe a scam, clean my email box weekly, including junk folder, Make sure to manually check for updates daily, or if I forget a day, then I immediately check soon as I remember for all apps on system, including Windows UWP Apps, I do have a tendacy to fall for folks saying Defender is all I need in other forums when I post on other forums with totally unrelated PC problems that aren’t even related to Antivirus or system security, I must stop falling for that type of stuff and switching programs so much, always been an issue with me
Back in 2005 I was a tester for Windows Live One Care, I know now I made mistakes then, getting virus samples, and attempting to run them, and some got right past Windows Live One Care then, (Bios root kits, MBR Rootkits, system was so bad, PC shop had to rebuild the entire system with new hardware, lesser hardware than the original system, but at the time I just finally wanted a working system. Switched back after that to using Symantec Norton Antivirus, til someone in January 2006, recommened Avast, and I switched immediately to Avast, and now if I can stop falling for those other peoples comments, and forums i’ll now keep Avast installed like that past on All systems
Hardware wise back then
Went from a AMD Athlon 2500+, Abit NF7-s (nforce chipset) Max amount of ram allowed, Creative Xi-fi Soundcard, Radeon 9600XT, and 120gb Hard drive, and 320GB Maxtor think was then
Replacement Hardware
Socket 754 Sempron (forget exact model)
Radeon 9800Xt
4GB of Ram
Western Digital blue IDE hard drive
Seagate 80gb or something it was as slave drive back then
So yeah I probably went from a fairly good build, to a really low end build for a few years, til received a Socket 939 AMD 64 3500+ for a few more years
