This version was created by officially updating the legitimate Jiangmin Antivirus Software KV2008 Portable Edition to October 29, 2008. After decompressing, it can be placed on mobile devices such as USB drives or portable hard drives for use. It can also be used and upgraded under any PE system. Double-click KVPortable.exe to perform a virus scan, and double-click KVUMon.exe to start virus monitoring (it's the first time that the portable edition can start monitoring!), which is very convenient and easy to use! If you cannot upgrade under PE, please run the KV Portable Edition PE Patch.exe made by zds.
It fixes the issue of not being able to upgrade under XP SP3 when using an outdated urlmon.dll.
