Detection — finding threats
Develop an effective strategy to detect intrusions when they occur. Configure these features
to detect threats:
• Update Task — Get automatic updates of DAT and scanning engine from the McAfee download
website.
• On-Access Scanner— Detect potential threats from any possible source as files are read
from or written to disk. You can also scan for potentially unwanted cookies in the cookies
folder.
• On-Demand Scan Tasks — Detect potential threats using immediate and scheduled scan
tasks. You can also scan for potentially unwanted cookies and spyware-related registry
entries that were not previously cleaned.
• On-Delivery and On-Demand Email Scanner — Detect potential threats on Microsoft Outlook
email clients using on-delivery scanning of messages, attachments, and public folders. Detect
potential threats on Lotus Notes email clients when messages are accessed.
• Quarantine Manager Policy — Specify the quarantine location and the length of time to keep
quarantined items. Restore quarantined items as necessary.
Response — handling threats
Use product log files, automatic actions, and other notification features to decide the best way
to handle detections.
• Actions — Configure features to take action on detections.
• Log files — Monitor product log files to view a history of detected items.
• Queries and dashboards — Use ePolicy Orchestrator queries and dashboards to monitor
scanning activity and detections.
Tuning — monitoring, analyzing, and fine-tuning your protection
After initially configuring VirusScan Enterprise, it is always a good practice to monitor and
analyze your configuration. This can improve your system and network performance, plus
enhance your level of virus protection, if needed. For example, the following VirusScan Enterprise
tools and features can be modified as part of your monitoring, analyzing, and fine-tuning
processes:
• Log files (VirusScan Console) — View a history of detected items. Analyzing this information
could tell you if you need to enhance your protection or change the configuration to improve
system performance.
• Queries and dashboards (ePolicy Orchestrator console) — Monitor scanning activity and
detections. Analyzing this information could tell you if you need to enhance your protection
or change the configuration to improve system performance.
• Scheduled tasks — Modify tasks (like AutoUpdate) and scan times to improve performance
by running them during off-peak times.
• DAT repositories — Reduce network traffic over the enterprise Internet or intranet by moving
these source files closer to the clients needing the updates.
• Modifying the scanning policies — Increase performance or virus protection depending on
your analysis of the log files or queries. For example, configuring exclusions, when to use
