Computer virus Flame discovered RoelShuvenberg, a computer security specialist at Kaspersky Lab. The malicious program is capable of collecting information, changing computer settings, taking screenshots, recording audio, connecting to chats. The Washington Post, referring to unidentified western officials, reported that Flame was developed by US and Israeli experts. The main purpose of creating the virus was to obtain the information necessary to disrupt the Iranian nuclear program. According to journalists, the Trojan program was developed as part of the program "Olympic Games", already "famous" for the Stuxnet virus. This virus became widely known for its destructive activity in the Iranian uranium enrichment center in Natanz. Flame was discovered after cyberattacks to Iran's refineries. According to some sources, this attack was carried out by Israeli specialists without consulting with their colleagues from the US, which caused great discontent among the latter. They can be understood - the virus became known, it was investigated by experts of anti-virus companies. Nevertheless, the virus is still very dangerous, effective ways to combat it have not yet been found. According to Kaspersky Lab's experts, it can take up to ten years to fully decrypt the virus. Such a long time is explained by the size of the Trojan program - it "weighs" about twenty megabytes, which is just a huge size for a virus. By its structure, a malicious program represents a set of tools for attacking remote computers. First, the base unit of the Trojan program is installed on the opponent's computer, after which up to twenty additional modules that perform specific spy functions can be loaded. The program can intercept network traffic, monitor keystrokes, record audio from a microphone. One of the modules of the virus is able to connect via Bluetooth to nearby cell phones and download all the information from them. Prior to its detection, the virus managed to hit more than six hundred computers, most of the attacks were on objects in the Middle East. In particular, Flame was used against Iran, the Palestinian Autonomy, Syria, Lebanon, Sudan, Saudi Arabia, Egypt.

Everything that exists today is harmfulSoftware can be divided into two categories: viruses and Trojans. The first simply perform on the infected computer some negative for the user or comic actions - for example, can erase files or completely format the hard drive, shut down the computer, make the user inaccessible mouse, display a message, etc. As a rule, the creators of viruses do not pursue selfish goals, most often such programs are written just for fun. But there are exceptions - for example, viruses that block Windows. The user sees a message in which he is invited to transfer some amount of money to a specific account, after which he will be sent an unlock code. Having encountered such a virus, you should remember the features of the message - in particular, the account number or phone number (if you are offered to refill the phone balance), then go from another computer to the sites of antivirus companies and look for the corresponding unlocker. But even if you can not remove the virus, the worst consequences are formatting the PC hard disk. The Trojan programs are the most dangerous. This type of malware is created to steal confidential data from a person. If the virus is usually visible on the computer, the Trojan program tries to completely hide its presence. Its task is to collect the necessary information - for example, logins, passwords, bank card data or online banking, etc., after which it is imperceptible to transfer everything to the owner of the Trojan. Quality Trojan programs are written by highly qualified programmers and can cost thousands of dollars. A well-made Trojan is completely invisible, it can not be detected by any antivirus program - until the data about the Trojan goes into the anti-virus database. Modern spyware easily bypasses firewalls. Having done its black work, many Trojans self-destruct, leaving no traces behind. You can find out that your computer was infected with a Trojan, after you have lost your money from a bank card, or you will be hacked by mailboxes, admin sites of your sites, etc. There is also a class of viruses like backdoors. Having infected your computer, the virus creates a loophole through it, through which the hacker gets full access to the machine. It can view and copy information from disks, delete or add something. A hacker can use your computer to scan networks and hack other computers to carry out attacks on servers. The management of thousands of compromised computers can be carried out from one center, in this case a botnet is formed - a network of infected computers that are subordinate to one person. Viruses and Trojans represent a huge danger, so they are struggling with all possible means. The main problem is that the principles of building and running the most common Windows operating system today give hackers a lot of opportunities for creating and implementing malicious software. OS developers try to close the gaps, but they still remain too much. Much more safe in this regard is the Linux operating system - it's no accident that many hackers use it. In any case, to protect against viruses and Trojans on your computer, you must have an up-to-date antivirus and firewall. Also, you should follow basic security rules - in particular, do not download or open suspicious files.
