How To Check System Files For Digital Signatures
Posted by malwarekilla in Anti-Malware Tools on 11 17th, 2009 | 9 responses
As many of you already know, files that do NOT contain digital signatures are usually suspected pieces of malware. To check your Windows system files for files that are not signed you can run sigverif.exe 
- Click the windows globe in the bottom left.
- In the search programs and files type "sigverif".
- Click Start. Sigverif will quickly scan your system files for unsigned files.
- A window will open showing you which system files are not digitally signed. Also, I log was created. You can access the log by opening sigverif.exe, clicking advanced and then clicking view log.
- There are some files that are LEGITIMATE and have NO digital signature. You can verify if a file that does not contain a digital signature is malware by uploading it to virustotal.com (which scans the file against dozens of av engines)
...just another tip for your anti-malware tookit.
