We also read up on the viruses, ransomware, spyware, and other malware of recent years to learn what threats try to get onto most people’s computers today. We spent dozens of hours reading results from independent labs like AV-Test and AV-Comparatives, feature articles from many publications such as Ars Technica and PCMag, and white papers and releases from institutions and groups like Usenix and Google’s Project Zero. Windows Defender, Microsoft’s built-in tool, is good enough for most people. The “best antivirus” for most people to buy, it turns out, is nothing. And after all that, we learned that most people should neither pay for a traditional antivirus suite, such as McAfee, Norton, or Kaspersky, nor use free programs like Avira, Avast, or AVG. If slowness is experienced, try running JIRA applications with virus checking disabled.We set out to do a standard Wirecutter guide to the best antivirus app, so we spent months researching software, reading reports from independent testing labs and institutions, and consulting experts on safe computing. Some Antivirus software may continue to impact JIRA applications even if these folders are excluded. If using McAfee Antivirus, ensure that the Jira's Java/Tomcat process is specified as a low-risk process in McAfee's On-Access scanner settings as recommended in Slow performance with Java-based applications when Endpoint Security or VirusScan Enterprise is installed.As noted above, Symantec Anti-Virus should be uninstalled.If using the start-jira.bat script to start Jira, please double-check the path. Note that the java.exe path could change if another Java version is installed. \jre\bin\java.exeif started manually, with start-jira.bat.\bin\tomcat8.exe.64 if configured as a service Alternatively, exclude Jira's process.Workaroundĭepending on the antivirus software, it may be possible to exclude certain files from scanning. Symantec Anti-Virus should be uninstalled, as our experiences with it have shown it to cause dramatic performance degradation even when the service is turned off. McAfee Agent 5.x has also been demonstrated to have a decremental effect on particularly search index performance due to the overhead added to open/close file operations even on directories explicitly excluded from scanning. ![]() McAfee's NetShield 4.5 in particular claims to let you exclude folders from scanning, though in previous investigations we have found this not to be the case - upgrade to version 7.0.0 to fix this. In some cases, even disabling the antivirus is not enough, and the server has to be restarted or even need have the anti-virus uninstalled. This happens because even though the AV service is disabled, the filter drivers are still running, and drivers run in kernel mode. Most anti-virus software causes a dramatic increase in disk IO and CPU usage when used with JIRA applications. As JIRA applications create many temporary files it is possible that due to disk I/O and resourcing, virus checking software can slow JIRA applications dramatically. ![]() Although we cannot directly recommend specific Anti-Virus software to use with JIRA applications we would like to advise our customers that if you are experiencing slowness with your JIRA application, try running it with virus checking disabled.
