In a blog post, Microsoft Malware Protection Center team notes, that the volume of online threats that attackers are developing continues to increase. "Our automated systems process many samples submitted to the MMPC and automatically add signatures for new malware. "For example, last month we collected and analyzed 20 million new potential malware files." "Six percent of these files were classified as malware"," the MMPC stated.

Further the team notes, that "from that six percent, just over 100,000 files resulted in the development of new signatures to detect these files - all to protect as many customers as possible and as quickly as possible."

These new signatures prevented three million customers from getting infected by four million unique malware files, while our existing signatures protected an additional eleven million customers from 72 million files, add the MMPC blog.

"For more established malware families, our researchers need to look deeper and overcome the new techniques the family is using to evade our protection," the team added.

For example, last month, the team protected 729,000 customers from Dorkbot infections. "However, if we didn't analyze the latest incoming files and write 361 new signatures fast enough, 70,000 of our customers would have been infected by Dorkbot's evasions," MMPC adds.
