Dell is caution users that "a few number" of its server motherboards might have hateful software.

"The possible issue engages a small number of PowerEdge server motherboards sent out during service dispatches that might have malware," as per the post on a Dell support forum. "This malware code has been noticed on entrenched server management firmware."

The malware issue influences an inadequate number of substitution motherboards in four servers, the PowerEdge R310, PowerEdge R410, PowerEdge R510 and PowerEdge T410 models, wrote Forrest Norrod, vice president and general manager of server platforms at Dell. It just potentially apparent itself when a customer has an exact pattern and is not running present antivirus software, Norrod wrote.

"Dell is conscious of the issue and is calling influenced customers. This issue does not influence systems as dispatched from our factory and is limited to substitution parts only. Dell has eliminated all impacted motherboards from its service provide chain and new dispatching substitution stock does not have the malware," Norrod wrote. Norrod did not offer additional facts on malware, how it affects servers and possible ways to fix it, but said further details will be posted soon at Dell's website.
