How to keep Viruses and Threats far away from your devices
Computer viruses are applications designed for harmful reasons and can infect a device without the owner being aware about the fact. Anyone with a device has to be careful of attacks when using their computer, tablet or mobile handset.
Steps to keep viruses at bay
- Install anti-virus software and keep it up to date: it usually prevents the device from known viruses. The anti-virus software on a device must be kept up-to-date so that it can deal with new threats.
- Never open email attachments that contain executable files – files with extensions such as .exe, .com and .vbs. They are capable of doing whatever wrong they have been programmed to do if opened.
- Never open email links that you don’t trust. Treat it as a source that you are not expecting, similar to executable files.
- Be careful when opening graphics or media files. Although graphics and media files themselves are not viruses, it is possible for a virus to be disguised as a graphic or media file by assuming a false extension, such as .jpg. Opening files like this allows the virus to infect the device.
- Download applications from official stores for smartphones or tablets. Even though many virus attacks still target computers and are more severe due to the volume of data that may be stored on a computer, viruses can also affect smartphones and tablets.
Some of the additional practices you need to keep on mind while using your PC……
1. Secure Your Network.
Many of our computers connect to our files, printers, or the Internet via a Wi-Fi connection. Make sure it requires a password to access it and that the password is strong. Never broadcast an open Wi-Fi connection. Use WPA or WPA2 encryption. WEP is no longer strong enough as it can be bypassed in minutes by experts. It’s also a great idea to not broadcast your SSID (the name of your Wi-Fi network). You can still access it with your device, you will just have to manually type in the SSID and the password. If you frequently have guests who use your Internet, provide a guest SSID that uses a different password, just in case your friends are evil hackers.
2. Think Before You Click.
Avoid websites that provide pirated material. Do not open an email attachment from somebody or a company that you do not know. Do not click on a link in an unsolicited email. Always hover over a link (especially one with a URL shortener) before you click to see where the link is really taking you. If you have to download a file from the Internet, an email, an FTP site, a file-sharing service, etc., scan it before you run it. A good anti-virus software will do that automatically, but make sure it is being done.
3. Keep Your Personal Information Safe.
This is likely the most difficult thing to do on the Internet. Many hackers will access your files not by brute force, but through social engineering. They will get enough of your information to gain access to your online accounts and will glean more of your personal data. They will continue from account to account until they have enough of your info that they can access your banking data or just steal your identity altogether. Be cautious on message boards and social media. Lock down all of your privacy settings, and avoid using your real name or identity on discussion boards.
4. Don’t Use Open Wi-Fi.
When you are at the local coffee shop, library, and especially the airport, don’t use the “free” open (non-password, non-encrypted) Wi-Fi. Think about it. If you can access it with no issues, what can a trained malicious individual do?
5. Back Up Your Files.
The best thing you can do is back up your files—all of them. Ideally you will have your files (your data) in at least three places: the place where you work on them, on a separate storage device, and off-site. Keep your files on your computer, back them up to an external hard drive, then back them up in a different location. You can use a backup service or simply get two external hard drives and keep one at work, at a friend’s house, at a family member’s house, or in a safe deposit box.
6. Use Multiple Strong Passwords.
Never use the same password, especially on your bank account. Typically, we use the same email address or username for all of our accounts. Those are easy to see and steal. If you use the same password for everything, or on many things, and it is discovered, then it takes only seconds to hack your account. Use a strong password. Use lower case, upper case, numbers, and symbols in your password. Keep it easy to remember but difficult to guess. Do not use dates or pet names.
So , these are certain areas where you need to be very careful while working on your computer and also when using your internet. Your awareness will make your computer safe and secure….
