Jeg får stadig advarsler fra antivirusprogrammet når jeg er inne på Rc-Marked. Gjelder angrep fra en trojan. Jeg ser også at en annen har samme problem, se annonse på Rc-Marked. RCMarked.no / OBS.Trojan OBS. Jeg bruker Microsoft Security Essentials. Er det noen som vet noe om dette?
Etter litt jobbing med MSE og nettet forøvrig fikk jeg fatt i følgende info:

Top
--------------------------------------------------------------------------------
Symptoms

Technical Information (Analysis)
Trojan:JS/IframeRef is the detection for JavaScript that attempts to redirect the browser to another website.
This JavaScript is usually found in webpages compromised through SQL Injection attacks or through Blackhat search engine optimization (SEO) poisoning. This detection may also be triggered if the webpage containing this script is stored in the browser's cache.
If the user vists a website containing this malicious JavaScript, the browser is redirected to the following URL:
dsnextgen.com/?epl=
At the time of publishing, the server is inaccessible.

Prevention
Take the following steps to help prevent infection on your computer:
•Enable a firewall on your computer.
•Get the latest computer updates for all your installed software.
•Use up-to-date antivirus software.
•Limit user privileges on the computer.
•Use caution when opening attachments and accepting file transfers.
•Use caution when clicking on links to webpages.
•Avoid downloading pirated software.
•Protect yourself against social engineering attacks.
•Use strong passwords.
Enable a firewall on your computer
Use a third-party firewall product or turn on the Microsoft Windows Internet Connection Firewall.
•How to turn on the Windows Firewall in Windows 7
•How to turn on the Windows Firewall in Windows Vista
•How to turn on the Windows firewall in Windows XP
Get the latest computer updates
Updates help protect your computer from viruses, worms, and other threats as they are discovered. It is important to install updates for all the software that is installed in your computer. These are usually available from vendor websites. Instructions on how to download the latest versions of some common software is available from the following:
•Microsoft Malware Protection Center - Updating Software
You can use the Automatic Updates feature in Windows to automatically download future Microsoft security updates while your computer is on and connected to the Internet.
•How to turn on Automatic Updates in Windows 7
•How to turn on Automatic Updates in Windows Vista
•How to turn on Automatic Updates in Windows XP
Use up-to-date antivirus software
Most antivirus software can detect and prevent infection by known malicious software. To help protect you from infection, you should always run antivirus software, such as Microsoft Security Essentials, that is updated with the latest signature files. For more information, see http://www.microsoft.com/windows/antivirus-partners/.
Limit user privileges on the computer
Starting with Windows Vista and Windows 7, Microsoft introduced User Account Control (UAC), which, when enabled, allowed users to run with least user privileges. This scenario limits the possibility of attacks by malware and other threats that require administrative privileges to run.
You can configure UAC in your computer to meet your preferences:
•User Account Control in Windows 7
•User Account Control in Windows Vista
•Applying the Principle of Least Privilege in Windows XP
•More on User Account Control
Use caution when opening attachments and accepting file transfers
Exercise caution with email and attachments received from unknown sources, or received unexpectedly from known sources. Use extreme caution when accepting file transfers from known or unknown sources.
Use caution when clicking on links to webpages
Exercise caution with links to webpages that you receive from unknown sources, especially if the links are to a webpage that you are not familiar with, unsure of the destination of, or suspicious of. Malicious software may be installed in your computer simply by visiting a webpage with harmful content.
Avoid downloading pirated software
Threats may also be bundled with software and files that are available for download on various torrent sites. Downloading "cracked" or "pirated" software from these sites carries not only the risk of being infected with malware, but is also illegal. For more information, see 'The risks of obtaining and using pirated software'.
Protect yourself from social engineering attacks
While attackers may attempt to exploit vulnerabilities in hardware or software to compromise a computer, they also attempt to exploit vulnerabilities in human behavior to do the same. When an attacker attempts to take advantage of human behavior to persuade the affected user to perform an action of the attacker's choice, it is known as 'social engineering'. Essentially, social engineering is an attack against the human interface of the targeted computer. For more information, see 'What is social engineering?'.
Use strong passwords
Attackers may try to gain access to your Windows account by guessing your password. It is therefore important that you use a strong password – one that cannot be easily guessed by an attacker. A strong password is one that has at least eight characters, and combines letters, numbers, and symbols. For more information, see http://www.microsoft.com/security/on...ds-create.aspx.

Recovery
To detect and remove this threat and other malicious software that may be installed on your computer, run a full-system scan with an appropriate, up-to-date, security solution. The following Microsoft products detect and remove this threat:
•Microsoft Security Essentials
•Microsoft Safety Scanner
For more information on antivirus software, see http://www.microsoft.com/windows/antivirus-partners/.
This threat may be present in your Temporary Internet Files folder. We recommend that you delete your temporary Internet files to prevent the persistent detection of this threat from within the Temporary Internet Files folder.
To delete the temporary Internet files from Internet Explorer, go to KB Article 260897.
