INVISUS® Computer Security, a PC security company for professionals and small business/home office users (SOHO) customers, today announced that its existing PC protection guarantee covers problems related to the MyDoom cyber-attack and others hybrid attacks like it. INVISUS is the only company that guarantees the protection of its customers' personal computers using its comprehensive security system, the INVISUS PC Security Solution. Although no customers have reported problems associated with this latest threat, this is great news for protecting sensitive information for professionals and small office computers. Even if an INVISUS user accidentally opens MyDoom, a second layer of protection stops the attack from making systems changes that open the door for later use by hackers.
