Is there anywhere in this forum that posts a list of free av's that are vista 32bit sp2 friendly?
No, but as townsbg pointed out, I have tried to maintain a list of security software that is unfriendly
to Vista (and Spybot is listed). The first post has been edited multiple times to add more products to the list, in fact as recently as yesterday. Frequent editing would be even more critical if someone tried to maintain a list of security products that do
support Vista, since support is temporary whereas "end of support" tends to be permanent; and readers might even expect you to actually test all those dreadful third-party products on an old Vista PC that you prefer to keep offline because browser support is already as bad as AV support is going to be in another year.
When Vista was new, AVG was a good choice; but by 2014 I had grown to despise AVG. I suppose it might have improved after Avast bought the company - but if that sounds likely to you, what's so bad about Avast? I used Panda Free for a short time more than three years ago, and would never
recommend it to anyone. If you had asked me back in 2016, I would've recommended Microsoft Security Essentials. Since you seem to have no qualms about relying on extremely old versions, I'll mention that Security Essentials 4.4 still works on Vista and XP (see Microsoft Security Essentials begins to nag on January 10
). When you say Avast slows down your computer, do you mean it slows down your browser?
Nearly every AV except Security Essentials slows down Firefox by increasing its memory footprint. (I sometimes wonder if Google pays AV companies to slow down Chrome's competition.) Firefox ESR 52 will soon be unsupported anyway (see Update on Firefox support for Windows XP and Vista – Future Releases
