Maybe a little more detail will explain my thoughts on Anti-Virus programs. .. ... I am a 80 yr old person living with 2 cats... and they don't care what's in my puter files, so I'm safe there.
many years ago during the "Win-XP" era when "Ready Made" anti-virus programs started appearing on the scene there were two that bragged how safe my computer would be with their program guarding it..
The first one I installed was Norton ...
the next day I turned on the computer and sat there watching a malware program actually "Eat" the Norton program and after 30 minutes of ranting and raving and calling Norton everything but a "gentleman" and "scholar" .. I dug out the re-boot disc that came with computers back then and reset it back to "Day 1" when it came out of the box brand new.
Next I installed McAfee... it was a little better ,,, it lasted almost a week before another malware program "Ate" it also.
So once again..I had to re-boot puter back to day one
for the next few years I tried several Anti-Virus programs on each version of windows that I bought and none of those other Anti-Virus programs did any better.
When W-7 came out I fell in love.. it was fast and was compatable to most of my old programs on my floppies and like XP it was easy and simple to use..
But this time I said the heck with all Anti-virus programs and tried something new and BINGO !!! .. it worked.
I installed three FREE programs on the W-7 and have not had any problems since.
Ccleaner ... Advanced System Care ... IOBit Malware Fighter ... and of course .. MS Security Essentials. I "run" each of the programs twice a week to keep the puters clean
I have 3 desktops with W-7 ... 2 laptops with W-7 ... and run a large mail order business using those computer and have never had a sucessful attack because these programs stopped the attacks instantly.
But to each their own, if an "anti-virus" program makes you feel safe thats great.. as for my "2 Cents" I'll stick with what I have ...
