AVAST Software designed FileRep to counter the growth of the polymorphic malware. Now with more than a billion unique files in our cloud, and more added daily, avast! FileRep technology lets you know whether a file is safe before you open it – determined in part by how many people have the file and how new the file is. The technology is also used internally, to help your avast! software’s scanning engine make more intelligent decisions by allowing it to skip clean files and more quickly detect potential malware and new ‘zero-day’ threats.
avast! FileRep is a database of executable files sourced from avast! Customers who have agreed to anonymously participate in the service. The files (or, rather, their hashes – i.e., identified versions of the files) are stored and evaluated for the purpose of determining which are infectious and for updating virus databases. Two key data categories tracked in FileRep are file age (emergence) and the number of computers that have already opened it (prevalence). Additional data categories tracked in FileRep are file distribution, the source URL, and digital signature status. The data is contributed anonymously by CommunityIQ members, the avast! customer network of anonymous front-line ‘sensors’.
Our FileRep database contains the reputation data of more than 2.5 billion files.
Every second we scan an average of 22.5 thousand files for our users.
Scans feel almost instant since it only takes 0.5 seconds to perform a scan.
