This can be quite a common question, you should exclude the following directories from your virus scan.
• d:\mysql
Note: If the mysql direcory is scanned, the anti-virus software is likely to quarantine or delete the files. The first symptom of this scenario is that your backups start failing.
• d:\mysql\temp
Note: If the mysql\temp direcory is scanned, the anti-virus software is likely to quarantine or delete the files. The first symptom of this scenario is that your backups start failing.
• d:\CW\<current_version>
Note: The following subfolder needs to be scanned:
d:\CW\<current_version>\scratch\temp\esadb\attCacheDir\
You should scan the following directory
d:\CW\<current_version>\scratch\temp\esadb\attCacheDir\
Note this is the directory where documents are placed temporarily during native viewing or where files are cached and as such should be scanned...
