Well, at me here is how time such situation - Win 7 x64, is not present any antivirus. Following measures are taken for safety: 1) everything Is disconnected that is not necessary. The list of operating services finds room on one screen. 2) is not present any software packages - office, studio, a photoshop, the reader, etc. Almost all programs small, with the open code. And the majority . 3) I Work exceptional under the restricted security account. 4) permanently works SimpleSoftwarePolicy - the thin superstructure over the standard group politicians, not giving to launch programs anywhere, except two-three allowed directories. 5) it is installed TinyWall - the thin superstructure over standard Windows, by default locks EVERYTHING, the output in the Internet is resolved only to a small amount of programs. 6) well, actually, in setting of new unchecked programs generally I am engaged rarely (yes it and is not necessary for me). I plan to buy license Sandboxie - I will launch almost all in . Here somehow so. While activity I do not note. Well and always anyway it is necessary to do .
