request for samples
I am a security researcher in the network security lab at Indian Institute of Technology, Guwahati. I am new to this field of malwares. Currently I am working on malware obfuscation techniques. I used a debugger to obfuscate given samples of malwares. So can anyone plz provide me some links of opensource antivirus softwares except ClamAV to get the signature of a particular malware from its database. Can anybody also give me some link of common obfuscators. It will be of great help.
