User Account Control has the role to block the installation and running of an application that brings changes in the system, without the consent of the user (yours). In the Windows 10, the UAC was developed and designed to no longer allows installation of programs that do not have "signed" / untrusted certificates - (more advanced level / I will explain in another article, soon what it means Trusted & Untrusted Certificates)

If adware is limited to launch advertisements on web pages accessed by the victim computer, a malware go ahead and can reach up to taking full control of the infected computer. Malware are designed to send automated mails SPAM victim computer, redirect the user to the web addresses where it is, cloned or encrypt confidential data irreversibly personal data stored.
Basically, the term "malware" is used generically for viruses of several categories: virus, trojan horses, worm, rootkits, backdoors, evasion. These names are given depending on the method by which the malware enters the system, its actions on the operating system and how it spreads to other systems / computers.
A brief overview of malware terms / categories:
Virus - a PC program that is hidden inside another program. It has the ability to create its own children and infect other files on the computer.
Trojan Horses - Or "The Trojan horse"It is a more complex type of malware. It can hide behind a seemingly harmless application and is designed not to be detected during installation, launch, and is very difficult to detect to be deleted or uninstalled. A trojan can immediately launch executable codes on the victim's computer and can cause significant damage to data stored on the hard drive. There have been many cases of irreversible encryption of documents, pictures and other files on your computer following infection with a CryptoLocker Trojan.
Worms - on the scrutiny, these rauintentionate programs can propagate themselves and you can multiply the number of files in an operating system and / or a local network. LAN.

A backdoor has the role of bypassing the authentication sessions (bypass). Usually these malware take access primarily to the internet connection and create security breaches to access the internet without the user's knowledge.
Rootkits - once a malware has been installed on a system, it must remain undetected by the user. Rootkits packages are responsible for hiding malicious processes Task Manager and modifying system files to not make it impossible to identify and stop viruses processes.
Evasion - is a relatively new technique in the "malware industry", and it helps the malware to run when the computer is started. Boot sequence. The "evasion" technique evolved a lot even in 2015, when it came to the design of malware that would block the installation of anti-malware programs on the infected system. Practically, this technique modifies important files of the operating system, so that it no longer allows the installation of programs. antivirus. Detection and evasion Cleaners type of malware is a real headache. Vonteera is such a malware / adware that gives headaches in this period of users Windows PC.

How can we prevent computer virus infection?
We mostly use practices similar to those described in preventing adware infection. An updated anti-virus and anti-malware software that runs in real time on the system, both when installing applications and when accessing web pages, and increased attention when attaching a memory stick or a hard disk external that comes from a computer without anti-malware. a firewall well configured and isolation in the local network system security is a plus.
De-virusing a computer is done depending on the type of malware that infected it and the importance of the stored data. If there are no important data stored on the computer, the most recommended is to completely delete a hard diskof the Formatting both the system partition and the data partitions.
Manufacturers of anti-malware provides solutions quite complex prevention and anti-virus, but there are malware that even if Elim on the system, data can not be recovered (such as virusarii with CryptoLocker) or corrupting system files and Register is irreversible.
