Stick to well-known video sites such as YouTube, or to download services like iTunes. Such downloads can happen just about anywhere. Some sites are built to lure people into a drive-by download; but in a common attack method, criminals will hack a Web page, often on an otherwise legitimate site, and insert code that will download malware to your computer.
If You Have to Go There: The first thing to do is to keep your security software up-to-date, and to run regular malware scans. Many security suites can flag suspicious downloads. Fake antivirus programs look and act like the real thing, complete with alert messages.
Most fake antivirus software is best described as extortionware: The trial version will nag you until you purchase the fake antivirus software-which usually does nothing to protect your PC. Once you send the criminals your credit card information, they can reuse it for other purposes, such as buying a high-priced item under your name.
You can get infected with a fake antivirus app in any number of ways. For example, in drive-by downloads see the previous item , a malicious payload downloads and installs without the user realizing it or having any time to react. Try booting into Safe Mode and running a scan using your legitimate antivirus software.
This may render behavioral detection which spots malware based on how it acts on your system useless. If all else fails, you may need to call in a professional. They help sites pay the bills.
But cybercriminals have taken out ads on popular sites to lure in victims. But as the Google Sponsored Links incident shows, nothing is entirely fail-safe.
Facebook apps have long been an issue for security experts. Take a few minutes to check your Facebook application settings to make sure that your app privacy settings are as you want them. There, you can control which apps have access to your data, and which of your friends can see what information from apps such as quiz results ; you can also turn off Facebook apps altogether. Get a free notebook! A free iPod! And then read them again.
Sites like Facebook have given rise to new forms of phishing. Be especially suspicious if the post is out of the ordinary for that person. And if you suspect that your account has been hijacked, change your password immediately. Both Facebook and Twitter have resources to help you keep up-to-date on the latest threats on both sites. How many times have you seen friends on Facebook or Twitter publicly divulge a bit more information than is necessary?

Jan 12, The site contains JavaScript code which generates an infinite string …. Dec 24, Randomly moves the window round. It was named by McAfee employee Craig Schmugar, one of the people who had originally discovered it. The worm spreads itself by appearing as an email transmission error and contains an attachment of itself.
The payload itself is twofold: first it opens up a backdoor to allow remote access and second it launches a denial of service attack on the controversial SCO Group. It was believed that the worm was created to disrupt SCO due to conflict over ownership of some Linux code. CryptoLocker is a form of Trojan horse ransomware targeted at computers running Windows. It uses several methods to spread itself , such as email, and once a computer is infected, it will proceed to encrypt certain files on the hard drive and any mounted storage connected to it with RSA public key cryptography.
While it is easy enough to remove the malware from the computer, the files will still remain encrypted.
The only way to unlock the files is to pay a ransom by a deadline. If the deadline is not met, the ransom will increase significantly or the decryption keys deleted. The ransom operation was eventually stopped when law enforcement agencies and security companies managed to take control part of the botnet operating CryptoLocker and Zeus. Evgeniy Bogachev, the ring leader, was charged and the encryption keys were released to the affected computers.
From data collected from the raid, the number of infections is estimated to be ,, with the number of those who paid the ransom to be at 1. Though not as damaging as the rest of the malware on this list, this is one of the few Mac malware to have gain notoriety as it showed that Macs are not immune.
The Trojan was first discovered in by antivirus company Intego as a fake Flash install. In its newer incarnation, a user simply needs to have Java enabled which is likely the majority of us.
It propagates itself by using compromised websites containing JavaScript code that will download the payload. Once installed, the Mac becomes part of a botnet of other infected Macs. The bad news is that more than , Macs were infected, including Macs in the Cupertino area, the headquarters of Apple. It is still out in the wild, with an estimate of 22, Macs still infected as of Malaria Mukt Bharat.
