Dr.Web Scanner can detect viruses in some mailboxes, but SpIDer Mail has a number of advantages:
- Not all popular mailbox formats are supported by Dr.Web Scanner, and if you use SpIDer Mail, infected emails do not even reach mailboxes;
- Dr.Web Scanner scans mailboxes, but only at the user's request or on a schedule, and not while a mail client is retrieving emails; and this action is very resource consuming and takes a considerable amount of time.
Thus, when all the Dr.Web components are configured with their default settings, SpIDer Mail is the first to detect viruses and prevent them and suspicious objects spread via email from reaching your computer. Its operation is highly advantageous in terms of computing resources; the remaining components don’t need to be used to scan email files.
