Malware writers, hackers and attackers have different motives for installing malicious software and also use different methods and techniques to distribute their malicious programs.
“Rouge” security programs are one of the most popular and common sources of malware infection. They usually infect the computers by using scams to trick a user into spending money to obtain an program which claims to remove malware. They usually use caution alerts and messages to indicate that your computer is “infected” with spyware or has significant errors as a scare tactic to send you into downloading a malicious security software to fix it. The alerts can copy system messages, so they appear as if they are generated by the Operating System. It is not uncommon for malware writers to use the names of approved and popular security programs as part of the name for fake anti-virus software in order to deceive people into using them. There are a couple of malicious security programs that use part of or the entire “Malwarebytes” name. Even Microsoft has been targeted by attackers using such names as MS Anti-virus or Microsoft Security Essentials for their false programs and incorporating the names XP, Vista and Defender into their names. When you get infected with this kind of malware, it’s good idea to choose professional computer repair technicians to do the job for you.
The “‘Rogue” programs are responsible for launching unwanted browser redirects, pop ups and downloading other malicious files so the extent of the infection can vary to include Botnets, Trojans, IRCBots and rootkits which will compromise the computer and make the virus more difficult to remove. Infections spread by attackers and malware writers exploiting vulnerabilities or unpatched security holes in older versions of popular software such as Java, Adobe, Windows Media Player and the Windows operating system. Software applications are a favored target of malware writers who continue to utilize design and coding vulnerabilities with increasing aggressiveness.
A large number of viruses are contracted and spread by visiting using pirated software (warez), cracking tools, keygens and gaming sites where visitors may encounter “drive-by downloads” through utilization of an operating system or a web browser vulnerability. Security researchers looking at World of Warcraft and other popular online games have found vulnerabilities that abuse the system using online bots and rootkit-like techniques to evade identification in order to obtain gamer’s login information so they can use their accounts! So if you suspect that your computer has a virus, it’s advisable to do a thorough computer repair.
Infections spread by using torrent programs. They are a security risk which can make your computer vulnerable to a smorgasbord of malware infections, remote attacks, exposure of confidential information, and identity theft. File sharing networks are easily infected and infested with malware! Backdoor Trojans, malicious worms and rootkits spread across P2P file sharing networks, gaming and underground sites. Users that visit such pages may see innocent-looking banner ads containing code which can generate pop-up ads and malicious Flash ads that install viruses, spyware and Trojans. Ads are a target for hackers because they offer a sly way to deliver malware to a wide range of Internet users. Hackers are also known to utilize Flash vulnerabilities which can lead to malware infection. When visiting a website that hosts an HTML page which requires a Flash script, users may experience a malicious Flash redirection or malicious script specifically written to utilize a vulnerability in the Flash Interpreter which causes it to perform automatically in order to infect a computer.
Infection can also spread by visiting social sites and through emails containing links to websites that use security holes in your web browser. If you click on an infected email spam or link, Internet Explorer launches a site that installs a Trojan so that it can run every time you startup Windows and download more malicious files. Email attachments ending with a .com, .exe,.pif or .bat from unknown sources can be malicious and release dangerous Trojan downloaders, worms and viruses which can use your address book to continue its spread to others.
Finally, backing up infected files, is a source of re-infection if they are stored to your computer.You can back up all your personal data files, valuable documents, photos to a CD or DVD, not a flash drive or external hard drive because they may become infected in the process. The safest practice is not to backup any screensavers (*.scr), executable files (*.exe), script files (.php, .asp, .htm, .html, .xml) or autorun (.ini) files because they may be infected by malware. Avoid backing up compressed files (.zip, .rar, .cab) that have executables inside them because some types of malware can penetrate into the compressed files and infect the .exe files within them. Some other types of malware may even disguise themselves by adding to the existing extension or hiding a file extension, so be sure you look closely at the full file name. If you cannot see the file extension, you may want to reconfigure Windows to show file name extensions.
