From Windows to Linux?

I have been repairing and maintaining computers for over 20 years. Started work at MSDOS. Then Windows 3.1; Windows 95, 98; Windows 2000 Finally, Windows XP. And today – Windows 7 and 8.

These operating systems were far from always satisfactory. Firstly – paid and not cheap. Secondly, applications are also mostly paid. The third point is unstable operation, crashes, glitches and, in connection with this, loss of information. Windows is susceptible to viruses.

And most importantly – it’s free. Yes, and almost all software is also free. At the initial stage of development, Linux was difficult for the average user, since Continue reading

What is the Morris Worm?

How to keep your computer healthy?

A computer is a universal tool that allows you to work, relax, chat, or shop. At the same time, even without visiting malicious sites, you cannot be sure of protecting your computer, as the search for vulnerabilities in the IT industry is always ahead of the development of protection. Thus, you should independently worry about the safety of your data with the help of an antivirus.

What is it and why is it necessary? The comfort of using a particular system is inversely related to security. This rule has some derogations, but in general terms it looks just like that. Therefore, no matter how comfortable it is to work, one must assume the possibility of hacking. Even by accessing regular pages and not clicking any unnecessary links, you can get malware onto your computer if the page you Continue reading
