112 Kaspersky Internet Security 7.0
When using this scan type, the full set of application databases is used,
which improves the level of malicious code detection. However, using this
algorithm increases object processing time, and hence makes web
browsing slower: it can also cause problems when copying and
processing large objects because the connection with the HTTP client can
time out.
One way to solve this problem is to limit the caching time for object
fragments downloaded from the Internet. When the time limit expires, the
user will receive the downloaded part of the file without it being scanned,
but once the object is fully copied, it will be scanned in its entirety. This
can deliver the object to the user sooner, and can solve the problem of
interrupting the connection without reducing security while using the
Internet.
To select the scanning algorithm that Web Anti-Virus will use:
1. Open the application settings window and select Web Anti-Virus under
Protection.
2. Click on the Customize button in the Web Anti-Virus configuration
window (cf. Figure 31).
3. In the window that opens (see Figure 32), select the option you want in
the Scan method section.
By default, Web Anti-Virus performs a buffered scan on Internet data, and uses
the complete set of application databases. The default caching time for file
fragments is one second.
