Updating mcafee detection signature
I continually (every 8-10 days) get the warning that my computer is not protected - "The detection signature file is between 8-29 days old".I follow its instructions and tell it to "Fix" and nothing happens.He says reputation technologies provide a far more predictable way of enhancing security."Users we've been talking to have been complaining endlessly about how a variety of the signature-based technologies have been failing them," Christiansen saysid.I have tried everything I can find but the only solution has been to totally remove the program from my computer and install it again.....every eight days......... Security experts and executives at security vendors are in agreement that signature-based antivirus isn't able to keep up with the explosion of malware.
A smart agent embedded into the VMware API can do the scanning of all the machines, greatly reducing performance issues, Chen says.
Trend Micro CEO Eva Chen says signatures are going to continue to be needed to protect computer users, but new technologies can help bolster the effectiveness of signatures. Chen says Trend has long used reputation technology, offering a threat detection appliance Chen developed that supports antivirus by monitoring files on the network for anomalies and tracking the destination of the files to detect problems.
The goal is to provide technology that is "content aware, context aware and location aware," Chen says.
Like F-Secure, the security giant also added heuristics and reputation-based engines to monitor potentially malicious file behavior.
Piero De Paoli, director of product marketing, calls the company's SONAR technology "advanced," and says the behavioral reputation engine (acquired by Symantec in 2005) can detect whether a file is acting suspicious.
Those that the user allows as good files would be added to the Whitelist while all others would remain in the sandbox, after which they would go to the Comodo labs for analysis.
