Caution: This is a purely amateur effort. It is not an exhaustive set of links on the topics involved. The shopping links may not contain the best or cheapest sources of information and gear, just places I happened to run into while looking for something. I haven't completely checked out and cannot vouch for any of these links. Some of this is specific to the D.C. Metropolitan area or the University of Maryland. A lot is not up to date.

Clonezilla Live My favorite disk backup tool for Linux and Windows.
Fast and Free. Not very user friendly, but stops on error, and runs under user control - extremely important. (Tools that continue after an error, and/or do automated backups to a permanently mounted drive, are mostly useless, because if a source or destination drive starts to fail, or if you are infected by a virus, the new (bad) backups overwrite the old (good) backups. Likewise, Microsoft Windows backup is too complicated to use, because of microsoft adds too many copy protection features - most people don't succeed in creating a usable backup.)
You should only run backups to a removable drive that you remove when not doing a back-up, under your control, and after doing a "chkdsk/b :" (under a cmdshell run with administrative privilidges) on all source drives (for NTFS drives), or run fsck on linux partitions, or backups may not be recoverable. (Once in a while, and before your first backup, you may also want to run chkdsk/b on your destination drive.) If Clonezilla still fails with an I/O error, despite this, you can go into expert mode, and try the -rescue and -z6 (lzip) options. Old Clonezilla fails on Windows 8 and Windows 10, but it is possible new haved fixed this - or at least I see people used it.
Clonezilla is sometimes used to Clone hard drives as well as back them up - but beware that Microsoft doesn't approve of multiple PCs running the same licensed copy of Windows. It may also not work.

Zone Alarm from Zone Labs I don't use this anymore, because it slowed everything down. Windows Security Essentials is mostly sufficient, if kept up to date, and you regularly use Windows Update.

PCMag: The Best VPN Services of 2017
U.S. ISPs can legally resell info about everything you do over the Internet to anyone - and they do. In addition, WiFi and most shared communication lines (such as are used for Internet) are easily intercepted, and any website can be spoofed to fool your browser into making you reveal your accounts and passwords. So using a VPN (Virtual Private Network), which encrypts the data, is often a good idea - if you trust the VPN service. (Since free VPN services must sell such info to make a profit, they probably can't be trusted.) Though a VPN may not stop anyone, like a government, willing to devote sufficient resources, from monitoring your activities (e.g., hiding your IP address and location may not work), so don't do anything illegal. Also, VPNs, like most things that rely on encryption, may not provide long-term privacy - in the long term, most secret codes can be broken, so intercepted data can be saved for future decryption. Yes, I'm being paranoid, but it is a well thought out paranoia. ☺

I tried two well rated VPN services, PureVPN and NordVPN. I had trouble accessing Yahoo and Google search engines and email, as well as video streaming services, and initially couldn't see PureVPN's own web page from PureVPN's own VPN server. But PureVPN tech support was very helpful, and found me (temporary) work arounds. They explained that many websites blacklist published VPN server IP addresses, which means they all work for a very limited period of time. So, while VPNs do help safeguard passwords, you should expect frequent unreliability when using commercial VPN services to access 3rd party servers. In addition, using a common VPN while logging in to gmail may be impossible, because they verify your IP address - unless you set up 2-step verification (e.g., verify you are you through a phone call - which won't work if you use Google Voice). (PureVPN suggested to always use the same VPN server IP address with gmail - maybe that would work.) The only reliable way to make a VPN work with 3rd party servers is to set up your own server, and not publish its existence. Some companies set up their own VPNs so their employees can access their own internal workplace networks. (Though, that can be a bad idea, if employees trust it too much, and ignore security.) Furthermore, VPNs usually slow down network access, and some ISPs deliberately slow down VPN and other proxy data.
PureVPN A well-rated relatively cheap VPN service, which I use.
NordVPN Another well rated VPN service that I tried.

Inexpensive Cell Phone services; Wireless Internet Service Providers

CellGuru comparison chart of prepaid cell plans. Some prepaid plans give you cell phone service for as little as $2 - $3 / month. But you pay extra if you make or receive too many calls, receive too many messages, or use too much Internet (especially video).
PagePlus Cellular I have used it. A Great service; everything works; great technical support; uses the Verizon service network; also sells cheap used compatible phones. I highly recommend it. The only issue is that they drop support on most cell phones that are more than two or three years old (a problem shared by most cell phone services).
  To forward Verizon or PagePlus voice mail to Google Voice, dial all 3 below on your Verizon or PagePlus phone:
  *71[Google Voice number] (Conditional forwarding: transfers to Google Voice if Verizon phone is busy or unanswered)
  *90[Google Voice number] (Busy Transfer: transfers to Google Voice if Verizon phone is busy)
  *92[Google Voice number] (No Answer Transfer: transfers to Google voice unanswered calls
LifeLink "Free" (government paid) cell phone and broadband Internet service providers for low income people. Someone I know tried one provider (Safelink), had unresolved technical support issues, and gave up. Perhaps other individuals will fair better. As with prepaid, costs extra if you use it too much.
The Best Deals On Prepaid Mobile Data Similar
"Free" Broadband Internet services
Note: As with free and repaid cell phone service, you pay extra if you use it too much. This surprises and makes some people very upset.
Freedompop A "Free" cell phone and wireless data service (after device purchase) available to everyone.
NetZero Another "free" wireless Internet service
"Freedompop's free wireless would be cool if it wasn't so shady" someone who got upset when they found out "free" had limits.
FreedomPop free plan is a bit dishonest; another such person
Free computer to computer/phone services (there are many others) (are these spyware?)
Yahoo Messenger with voice (Also has 2 cent/minute link to land line)
Skype (I use. Erratic connection quality, but usually works.)
MagicJack A Skype competitor (I have tried it; Usually reliable, except you won't hear the first first few seconds of calls.
netTALK Another competitor (not tried by me.)
Google Voice, About Google Voice You get a permanent free phone number to use with the google voice app, or through your home computer, which can also forward calls to other phone numbers, and take voice mail. You can also make outgoing calls by using the Google Hangouts dialer, or by calling your Google voice number from another phone. A bit complicated to set up, but a great Free service.

Shopping, general

Caution I've recently had bad experiences ordering stuff from China. All the sellers had 97%+ positive feedback from eBay. Many others now tell me that you should only buy from 99.6%+ positive feedback sellers listed by eBay as top rated sellers - and read all the negative feedback. If anyone says they didn't get what they ordered, or that the seller delayed and delayed, or told them not to give a negative review, or had bad English - stay away from them. Make sure they have been selling through eBay for a few years, with 10,000 or more sales. Oddly enough, this didn't used to be true. I wish the Chinese government regulated merchants more carefully.

WARNING Many online insurance and medical and discount discount plans are scams. Always sign up for insurance or discount plans, or anything financial, through the main company, not a broker. Use large well respected companies, and find their web site or other contact info through a respectable source. (I sometimes use Wikipedia to find companies - not perfect, but much better than a search engine.) Also, most insurance and discount plans explicitly bar your having other insurance and discount plans. If you use two companies, neither will pay or apply. I have not verified either of the next two sites below - do so yourself before buying anything.
Health insurance and medical discount plans; may be useful for comparison shopping, but I suggest you go to the main insurance company to buy; don't go through them.
Cinergy Health Insurance that covers the expenses you are most likely to need, but not catastrophic care. Perhaps because some health providers only work with insured individuals?
