Computer security

Do you have a password on your computer to sign in?

Creating strong passwords:

You’ll need to create a password to do just about everything on the Web, from checking your email to online banking. And while it’s simpler to use a short, easy-to-remember password, this can also pose serious risks to your online security. To protect yourself and your information, you’ll want to use passwords that are long, strong, and difficult for someone else to guess while still keeping them relatively easy for you to remember.

The best way to create a password is to use a sentence such as:

My2legsfellAsleepon910

Thecatisloosenow3times

mynameisWill7771backhome

Managing user accounts and parental controls

user account allows you to sign in to Windows 10. By default, your computer already has one user account, which you were required to create when setting up Windows for the first time. But if you plan to share your computer, you can create a separate user account for each member of your home or office.

I always have at least two administrator’s accounts in case something happens to one.  I had to delete one accounts using my other accounts because of a virus.  I lost the account and information associated with it but was able to fix my computer load a new admin accounts and restore the information from backups.

If your computer is slowing down and behaving erratically, you might have a virus or spyware app to contend with (or you might just have a really old computer). If you’ve already got antivirus software set up, then most threats should be blocked, but there’s always a chance that something has crept through—like a freeware app that isn’t what it says it is.

The obvious place to start is with whatever antivirus program you have: Update its definitions and run the most thorough scan it can offer. It’s possible that since the malware took hold, your security app has been updated to spot it (security companies’ say a lot of the CIA’s preferred hacking tools have now been blocked).

Weeding out viruses or spyware that are already on board your machine can be difficult though, as they’re often built to evade standard removal tools. Specialist on-demand scanners, such as the ones offered by KasperskyBitDefenderSuperAntiSpyware and Microsoft can run thorough scans and remove threats without installing a full security suite on your PC.

Between your browser’s security measures and the antivirus software you have installed at the OS level, a lot of bad actors should get spotted and deleted. If you need extra help then use a separate tool to double check, like the one provided by Googlethis utility from Avast or this free extension from security firm Qualys.

Changing your passwords online is a smart way of booting out anyone who’s in your accounts who shouldn’t be, but there’s more you can do. Check for activity inside your accounts that you don’t recognize, which is an option with most services: activity logs can be found here for Facebook, here for Twitter, and here for Google, for example.

Malware (short for malicious software) is software designed to infiltrate or damage a computer without your consent. Malware includes computer viruses, worms, trojan horses, spyware, scareware and more. It can be present on websites and emails, or hidden in downloadable files, photos, videos, freeware or shareware. (However, it should be noted that most websites, shareware or freeware applications do not come with malware.) The best way to avoid getting infected is to run a good anti-virus protection program, do periodic scans for spyware, avoid clicking on suspicious email links or websites. But scammers are sneaky: sometimes malware is cleverly disguised as an email from a friend, or a useful website. Even the most cautious of web-surfers will likely pick up an infection at some point. If you do, there are plenty of FREE TOOLS available to help you remove it. I list several below.

Virus:  Malware programs that can reproduce itself and infect other computers.

Spyware: It surreptitiously monitors and collects information about you, your computer and/or your browsing habits without your consent — usually for advertising purposes. It can also gather info from your address book, and even your passwords and credit card numbers. Unlike viruses and worms, spyware does not usually self-replicate. (Learn more )

Scareware: You’re surfing the net and suddenly an official-looking screen pops up warning you there is a problem on your computer, such as: “Your computer may be infected with harmful spyware programs. Immediate removal is required. To scan, click ‘Yes'”. You’re not sure if it’s real or not, so what do you do? Be careful, this might be scareware. If there’s any doubt, you can close your browser immediately by pressing ALT+F4 (Mac users: press Command/Apple+Q) This will prevent any scareware from loading

Don’t Trust Public Wifi

If you surf the web whilst sipping your latte in your local coffee shop beware! Did you know that much of your internet connection (web browsing and email) is being sent over the connection unencrypted? Anyone malicious in the coffee shop could be listening in and stealing your passwords. If you have a 3G connection then use that, but if not, you’ll need to secure your connection. Websites that use https (Facebook and Twitter for example) encrypt your data, but most websites won’t. For this, you’ll need to use a VPN or virtual private network. This encrypts your connection by connecting to a secure server in the middle. Use a VPN service here is a link to some https://www.pcmag.com/article2/0,2817,2403388,00.asp

Your browser’s security features

Your computer faces different threats whenever you browse the Web, including virusesmalware, and spyware. The good news is your web browser has a lot of built-in security features to help protect your computer. Let’s take a look at some of the most important features you should know about, as well as some simple tips you can use to stay safe online.

Check the web address

Malicious websites often use deceptive web addresses to trick users. For example, www.wellfargo.com looks similar to www.wellsfargo.com, but it’s missing the s in the middle.  Double-checking the domain name is a good way to ensure you’re going to the real, trusted site—not a phony site with a similar web address. Some web browsers will even try to make the domain name easier to read. In the example below, you can see that wellsfargo.com uses a darker color in the address bar.

Look at the security symbol

Some websites will display a lock symbol in the address bar. This is most commonly seen with certain types of websites, like online stores and banking sites. This means the website is using an HTTPS connection, which makes it safe to enter your personal information.

You won’t see this symbol on all websites, and that’s OK—not all weComputer security class Sat 1bsites need this extra layer of security. However, you should avoid entering any sensitive information, such as your credit card number, if you don’t see this symbol in the address bar.
