A webmaster I've been dealing with about an allegedly virus-laden file claims that many online malware scan sites are invalid for scanning Win XP/SP3 files because the sites use Linux versions of A-V engines; i.e., it's necessary to use a Windows-specific program for a valid scan. Two examples online that use 20 to 30 well-known and lesser-known A-V engines to scan files are http://virusscan.jotti.org/ and http://www.virustotal.com. Is there any truth to the webmaster's claim?
