V3.co.uk: Security vendors aren't happy about Microsoft's free antivirus protection, Microsoft Security Essentials (MSE). Panda Security's Luis Corrons compares it to the browser issues that resulted in a European lawsuit. "It's pretty similar or even worse, because at least with browsers you can still have two or three running on a machine at once and nothing happens," he said. "But because two anti-virus products don't usually work together, if you've already got one [MSE] installed you can't install a new security product unless you remove it."
Another Panda employee, Pedro Bustamante, noted, "If pushing MSE via Windows/Microsoft Update is very successful it will end up creating a monoculture of hundreds of millions of users having the same anti-virus product. Right now hackers have to worry about bypassing multiple anti-virus products and protection layers every time they release a new piece of malware. Having to bypass only one product makes their life so much easier."
