I know that, as a Mac user, I shouldn't say this but if your Windows PC is full of bloatware, spam, crap, blah blah blah .... who's fault is that?
I'm not a lover of Windows based computers but I have to have 3 of them running here to do my job. I'm based at home and all 3 machines are running XP Pro (SP3). 2 of them are Compaqs from about 2002 and the other is a netbook from around 2008.
Both Compaqs put in about 10 hours each day on the web doing various jobs and doing them almost as well as they did on Day 1.
How has this miracle come about? I hear you ask.
Simple. NOTHING gets downloaded and used without passing an up to date AV programme (I use the free version of Avast) + an Antimalwarebytes scan + a Superantispyware scan. And when I say "Nothing", I mean Nothing. Not even e-mails from family and friends because you never know where THEY got the info that they are sending that they think is perfectly safe to send.
Also, I have a prog that I run every 3 days on all of them.
This prog shuts down from the web and then fires up a new connection. It then connects to the Avast website and downloads the latest updates before doing a full scan of the computer. It then goes to the Antimalware website, downloads any updates and does a full scan of the system. Next is a defrag and then the computer shuts itself down.
Bloated? ..... No.
Full of malware, worms, trojans, viruses etc? ... No.
Working well even after 9 or 10 years? ..... Absolutely.
Like I said, I'm no great lover of Windows machines but I think it's more a case of not liking the way the software creators work rather than having a downer on the hardware.
With apologies for the rant.
