Many friends are asking, why move the virus database? Some people even directly told me, "Why didn't you install it on another drive during installation?" Here, I want to clarify that Kaspersky's virus database is by default installed in the directory C:\Documents and Settings\All Users\Application Data\Kaspersky Lab. Even if you choose to install the program on drive D during installation, the virus database still defaults to the system drive. If you don't believe me, you can look for it yourself!!!
