Beginning more than a decade ago, one of the largest security companies in the world, Moscow-based Kaspersky Lab, tried to damage rivals in the marketplace by tricking their antivirus software programs into classifying benign files as malicious, according to two former employees.
They said the secret campaign targeted
Microsoft Corp (MSFT.O), AVG Technologies NV (AVG.N), Avast Software and other rivals, fooling some of them into deleting or disabling important files on their customers' PCs.
Some of the attacks were ordered by Kaspersky Lab's co-founder, Eugene Kaspersky, in part to retaliate against smaller rivals that he felt were aping his software instead of developing their own technology, they said.
"Eugene considered this stealing," said one of the former employees. Both sources requested anonymity and said they were among a small group of people who knew about the operation.
Kaspersky Lab strongly denied that it had tricked competitors into categorizing clean files as malicious, so-called false positives.
