No anti-virus can detect the newest malicious programs 100 percent of the time. Even tests designed to detect malicious programs created after the latest anti-virus update say nothing about an anti-virus’s capacity to reveal the ‘infection’ created by criminals familiar with the anti-virus. Such anti-virus programs will not be detected by an anti-virus right up to the moment the necessary update is received.
That’s why the choice of an anti-virus should not be based on “test” results, but on an understanding of the following features of an anti-virus system:
- An anti-virus has to have a reliable system of self-protection— criminals must not be able to disable the anti-virus (or one of its components).
- Anti-virus updating and control systems must be completely under the control of the anti-virus’s self-protection system and must not use system components that are not under its control.
Once a company’s computers fall into a botnet, they often become a source of spam, and that harms the company’s reputation among its partners. Using Dr.Web Mail Security Suite and Dr.Web Desktop Security Suite will significantly reduce a company’s risk of becoming compromised by being blacklisted and disconnected from the Internet for acting as a spam bot.
A system for scanning mail traffic must be installed on the server as well as on the work stations, because incoming and outgoing messages go not only through a company’s mail server, but also directly through employees’ PCs (via SMTP, pop3/imap4 and closed links). In addition, the mail server (or the programs installed on it) can create mailings, including unwanted messages.
