Today is very difficult to imagine life without a computer with Internet access. Increasingly, we have fun, work, make purchases there. But where there's money there, and crooks.
Let's start with viruses. This specific various methods are willing to harm the computer. There are different viruses, including those that encode the user's data, steal passwords and logins, etc. the Purpose of their writing - or to get money or just to hurt him of hooliganism.
To counter a virus attack, a regular user can be very limited. Mandatory measures - installation of antivirus, keeping databases up to date (update), regular inspection of the computer hard drive and a removable disk antivirus. No less important is attention. Do not download files from untrusted sites, as well as those sent via e-mail by unknown senders. It is not necessary to open these downloaded files on a PC without checking them with antivirus. And of course, you cannot run executable files (their extensions, in particular .exe, .bat .cmd .pif .hta, js, .vbs...).
Without care and attention not to do when surfing the Internet using free wireless networks. In a café it is not necessary to commit important transactions (in particular, to use Internet banking). In addition to using antivirus on the PC, unplug the connection to the nearest network by default.
Don't forget about phishing. I have already described the essence of this fraud, so let me just remind you about the need for extreme caution and attention when making money transactions. Do not poke the mouse on a button just because it suddenly appeared. Especially if these buttons are bright, eye-catching.
Useful tip: when visiting your mailbox, social networks, other important and necessary services, never put a tick in "Save password" or "remember". Create complex and long password every time you dial them manually. Change your passwords at least once a month!
