BLOCKING DANGEROUS SCRIPTS
Web Anti-Virus can scan all scripts processed in Microsoft Internet Explorer, as well as any other WSH scripts
(JavaScript, Visual Basic Script, etc.) launched when the user works on the computer. If a script presents a threat to your
computer, it will be blocked.
In order for Web Anti-Virus to scan and block scripts:
1. Open the main application window.
2. In the top part of the window, click the Settings link.
3. In the left part of the window, in the Protection Center section, select the Web Anti-Virus component.
4. Click the Settings button in the Security level section in the right part of the window.
5. In the Web Anti-Virus window that opens, in the Additional block, the Block dangerous scripts in Microsoft
Internet Explorer box should be checked. If this box is unchecked, enable it.
CHECKING URLS USING THE DATABASES OF SUSPICIOUS AND
PHISHING ADDRESSES
Web Anti-Virus scans web traffic for viruses and checks the links if they are included in the list of suspicious or phishing
web addresses.
Checking the links if they are included in the list of phishing addresses allows avoiding phishing attacks, which look like
email messages from would-be financial institutions and contain links to the websites of these organizations. The
message text convinces the reader to click the link and enter confidential information in the window that opens, for
example, a credit card number or a login and password for an Internet banking web page where financial operations can
be carried out. A phishing attack can be disguised, for example, as a letter from your bank with a link to its official
website. By clicking the link, you go to an exact copy of the bank's website and can even see the real address in the
browser, even though you are actually on a counterfeit site. From this point forward, all your actions on the site are
tracked and can be used to steal your money.
The lists of phishing URLs are included with the Kaspersky Small Office Security delivery set. Since links to phishing web
sites may be received not only in email, but also from other sources, such as ICQ messages, Web Anti-Virus monitors
attempts to access a phishing web site on the level of web traffic and blocks access to such locations.
To configure Web Anti-Virus to check URLs against the databases of suspicious and phishing web addresses,
perform the following steps:
1. Open the main application window.
2. In the top part of the window, click the Settings link.
3. In the left part of the window, in the Protection Center section, select the Web Anti-Virus component.
4. Click the Settings button in the Security level section in the right part of the window.
5. In the Web Anti-Virus window that will open, in the Scan methods section, the Check if URLs are listed in
the base of suspicious web addresses box and the Check if URLs are listed in the base of phishing web
addresses box should be checked. If these boxes are unchecked, enable them.
USING HEURISTIC ANALYSIS
During Mail Anti-Virus operation, signature analysis is always used: Kaspersky Small Office Security compares the object
found with the database records.
