\n Protection from harmful software <\/h2>\n <\/div>\n<\/section>\n\n\n
\n
\n
\n

The first thing that will help you protect your devices from viruses is to install anti-virus software.<\/p>\n

Recommended software: Avast, ESET, McAfee, Zillya.<\/p>\n

How not to get attacked by fake antivirus?<\/b><\/p>\n

Only download the antivirus software from the official developer\u2019s website or from verified sources (Play Market, App Gallery, App Store \u0456 Google Play). If you can\u2019t buy a paid version of the program, find a free analogue, but don\u2019t download cracked versions of paid apps.<\/p>\n

Update your antivirus regularly. Only then will the program warn you about the threat in time.<\/p>\n

Antivirus is installed. What\u2019s next?<\/b><\/p>\n

Regularly scan your device for threats that could harm your data.<\/b><\/p>\n

Also use the anti-virus to check USB sticks and other external devices that you connect to your computer.<\/p>\n

Periodically \u201creset\u201d the settings of your smartphone.<\/b><\/p>\n

In this way you can neutralize the \u201ckeylogger\u201d programs that track the user\u2019s actions.<\/p>\n

Do not click on questionable links. Such as:<\/b><\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n\n

\n
\n
\n
\n

received from unknown senders via email, SMS or messengers and social networks;<\/p>\n<\/div>\n <\/div>\n

\n

messages with a call for urgent action and those that use a highly relevant and frequently mentioned topic in the media;<\/p>\n <\/div>\n

\n

those that lead to questionable sites or channels in social networks;<\/p>\n <\/div>\n

\n

those that do not have a security protocol: https \u2013 safe, http \u2013 potentially dangerous;<\/p>\n <\/div>\n

\n

containing the word \/download\/ \u2013 these links will immediately begin downloading the file. Attackers will probably download malicious code or lead to a phishing site.<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n

\n
\n
\n

Pay attention to a sharp and noticeable change in the operation of the device:\u00a0<\/b>a sharp decrease in charge, slow operation, the appearance of files that you did not create or programs that you did not install,\u00a0the appearance of unknown programs in autoload when the device is turned on, etc.\u00a0Maybe this is a consequence of the activity of harmful programs.<\/p>\n

Set secure messenger settings.<\/b>\u00a0How to do this\u00a0is explained here<\/a>.<\/p>\n

Set secure browser settings.\u00a0<\/b>How to do this\u00a0is explained here<\/a>.<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n\n

\n

Follow these simple rules:<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n\n

\n
\n
\n
\n

Change passwords on social networks, bank accounts and all websites where your personal information may be present, to safe ones. It is recommended to change all passwords once a month.<\/p>\n<\/div>\n <\/div>\n

\n
\n

Check regularly if your password has been hacked. Here is\u00a0a useful service<\/a>\u00a0where you can do it.<\/p>\n<\/div>\n <\/div>\n <\/div>\n<\/section>\n\n\n

\n
\n

\n How it works: enter your email or phone number on the website. If the passwords of the accounts registered on them have been hacked, the site will notify you. If not, there were no breaches of your data. <\/p>\n

\n
\n

Use password managers \u2013 these are special applications that keep your passwords in an encrypted form, and you won\u2019t have to remember all the complex combinations, but only the password from the application itself.

\n

Two-factor authentication \u2013 is a standard two-step verification when logging into an account. Set it up. Then, in case of a hack you will receive an SMS message asking you to confirm the login into account.<\/p>\n <\/div>\n

\n
\n

Set a screen passcode, pattern key, or biometric security (fingerprint, face ID or voice ID) to unlock your devices.<\/p>\n<\/div>\n <\/div>\n

\n

Change the standard PIN-code to SIM-card.<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n

\n
\n

\n
created using a password generation service (for\u00a0example<\/a>)<\/div>\n <\/div>\n
\n
\n

used only in one service (for each service or mailbox \u2013 a unique password)<\/p>\n<\/div>\n <\/div>\n

\n

not stored on your smartphone or laptop notes or on a sticker on a laptop standing in the middle of the office<\/p>\n <\/div>\n

\n
they are not in the\u00a0haveibeenpwned.com\/Passwords<\/a>\u00a0database<\/div>\n <\/div>\n
\n
\n

they aren\u2019t known by your relatives, loved ones, colleagues<\/p>\n<\/div>\n <\/div>\n

\n
