According to ESET, a provider of antivirus services in Southern Africa, some versions of MS Excel are vulnerable to malicious programs. The company advises that users should open files with caution.
Says Justin Stanford, CEO of ESET: “Excel users should refrain from opening suspicious .xls files or files received from unknown senders,”
The malware program, catalogued as “X97M/TrojanDropper.Agent.NAI. Trojan”, attacks versions 2000, 2002, 2003, 2007, 2004/2008 of MS Excel, among others. The Trojan creates a backdoor in the users system, allowing control over the victim’s workstation from a remote location.
