AntiVir is an anti-virus program I hadn't heard of before. It handles just about everything you can throw at it. Here is the list:

• Extensive Malware Recognition of viruses, Trojans, backdoor programs, worms, etc.
• Automatic incremental updates of antivirus signatures, engine and entire software
• Permanent virus protection, with Virus Guard real time monitoring
• Install and configuration in just a couple of steps, setup to protect your PC in minutes
• Virus protection against known and unknown threats, using an advanced heuristic system
• Scheduler where you can set the scanner to make automatic virus scans or updates on your system
• Forum and phone support, Knowledge Base with virus descriptions available on web site

If you are sick of your current anti-virus client, check out AntiVir personal edition. One of the features I like the best is the real-time system protection that monitors a user's actions and any changes made to the system.
