SQL Server database files typically have. SQL Server opens a database when it starts or when a database with Auto-Close enabled was closed and is accessed again. If the virus sweep software has opened a database file when SQL Server tries to open the database, the database to which the file belongs might be marked as suspect.
This kind of scanning may cause the following SQL Server database recovery and SQL Server full-text catalog file issues: It detects issues after files are infected by a virus. Virus sweep software: Virus sweep software scans existing files for file infection. Antivirus software typesĪctive virus scanning: This kind of scanning checks incoming and outgoing files for viruses. Servers that don't meet the criteria for a high-risk server are generally at a lower risk, although not always.
The servers use Database Mail to handle incoming or outgoing email messages. 
The servers run HTTP servers, such as Internet Information Services (IIS) or Apache. The servers read or execute files from other servers. 
The servers have open ports to servers that aren't behind a firewall. The servers are open to the public Internet. The highest-risk servers generally meet one or more of the following criteria: The risk of either viruses or bad information propagating from that computer.Īny server is at some risk of infection. The cost of losing access to the information. The required security level for the information. The business value of the information that's stored on the computer. Security risk factorsĬonsider the following factors when deciding on anti-malware solutions: Software to determine whether there's any performance effect on the computer that's running SQL Server. You must perform testing before and after you install your antivirus Virus protection software requires some system resources to execute. Based on the assessment, you must select the appropriate tools for the security risk level of each computer that's running SQL Server.Īdditionally, we recommend that you test the entire system under a full load to measure any changes in stability and performance before you roll out any virus-protection software. We strongly recommend that you individually assess the security risk for each computer that's running SQL Server in your environment.
