This technique actually is to disable the autorun.inf feature is usually found in the CD presentation, company profile or driver installation software. *** And this feature is typically used by virus makers to transmit the virus to the host system. Try and prove it by inserting the CD presentation / driver installer by pressing simultaneously the SHIFT key for a few seconds (usually to the sound round of CD Drive stops) ... shall flash a screen or presentation program will not appear.
One symptom that our operating system is infected with the virus feature malfunctioning Tools> Folder Options> View> Show hidden files and folders. Or even no option Tools Folder Options ... remember the eagle? :)) Well ... it could have fitur2 intentionally disabled by the administrator via Windows SteadyState or the other way, so do not be afraid buru2 used when "gejala2" over there on your system.
Install Windows Defender, Malicious Software Removal Tool (both available on the Microsoft website, ready to be downloaded), a good antivirus program (well, actually I have rekoendasi, but instead accused of "selling" ... hehe) and update regularly. Activate the automatic update feature ... or download updates and ask for installation of us who do not want to interfere operating system performance, especially in saat2 where we're doing a presentation or working on critical proyek2.
