How to keep your computer running smoothly (Windows).
Always make sure your computer is using a "SSD" (Solid State Drive) as a hard drive as opposed to a HDD (Hard Disk Drive) hard drive since SSDs are more reliable and make your computer boot up faster. If it still has an HDD than take it to a professional to get it replaced with a SSD.
Make sure your computer is at the very least Windows 10. If it's older than Windows 10, upgrade it ASAP. Take it to a professional if you have to, Windows OS's older than Windows 10 are highly vulnerable to malware.
Every two to three weeks, click on the search bar in the lower left hand side of your desktop or just click on the magnifying glass and type "Check for Updates." Then update your Windows machine until you can't update it anymore. Don't forget "Optional updates" as well.
Type in the search bar "Ransomware protection." Make sure it's enabled.
Type in the search bar "Default apps" and make sure your preferred internet browser is set as default. Windows will try to guilt you into staying with Edge browser, just hit continue anyway.
For your preferred browser of choice make sure you have Ad Block Plus extension installed. This will make sure you don't accidentally click on any malware-laden advertisements.

How to increase the longevity of your iPhone:
If theirs a new update from Apple, always ALWAYS take time to update your iPhone to the latest iOS.
Make a point of replacing the battery every 3 years give or take since that's the average life span of how long it takes for lithium batteries to run well before they start losing their integrity. A $60 - $90 battery replacement is a lot cheaper than having to buy a $1,000 new phone.
Make sure your storage is less than 90% capacity. A phone with storage close to completely full will have nothing but problems down the road until you free up storage up to and including your entire operating system being corrupted and you having no choice but to factory wipe your phone. If deleting videos, photos, podcasts, etc. doesn't free up enough space and the ubiquitous "other" or "system information" is taking up the vast majority of space than your most likely going to have to factory wipe your iPhone to get enough space again.
Tech support scams.
While it may be tempting to google up free tech support numbers the second your computer has problems to save money by way of not having to take your computer to a local repair shop, it's actually quite dangerous and can result in losing potentially thousands of dollars in garbage anti-malware programs or having your own computer compromised.
Pretty much any phone number on Google or random pop-up that claims to advertise tech support services is most likely either trying to sell you their garbage software products or trying to install dangerous malware onto your computer. It's better to just take your computer to a reputable repair shop in your own community than to trust a complete stranger over the phone.
