• HashTab - Check the file integrity and authenticity of your files.
• Microsoft File Checksum Integrity Verifier (FCIV) is command-line utility that computes and generates MD5 or SHA-1 cryptographic hash values for files to compare the values against a known good value to verify that windows files have not been changed.
• IE8 Hardening Tool – The IE8 hardening tool works by changing the values for a couple dozen different settings that control how IE8 operates and what is permitted. The tool primarily disables code execution via ActiveX and JavaScript. These changes are based upon recommendations from Microsoft, as documented in the recently published ‘Internet Explorer 8 Desktop Security Guide.’

Online Scanning Tools:

• VirusTotal – Free Online Virus and Malware Scan: (Virus total will scan a file in question with 39 virus scanners avoiding the dreaded false positive warnings) This is the best online scanner available for scanning single or multiple files on the net in my opinion.
