Known Issue with Beta2 Synchronous & Background Scan
We have received some comments and reports from Beta2 users of version 0.08.82 of slowness of their PCs and lots of hard drive I/O activity from PSANHost.exe.
We are tracing this problem back to an interaction of the new synchronous OnAccess cloud-scan with the BackgroundScan. This interaction seems as it could be the source of the slowness of the system even though we continue investigating it. Basically this occurs under certain circumstances when both scans are consuming the same resource. We’re in the process of redesigning these two scan tasks so they are optimized in the use of critical system resources to avoid simultaneous accesses to common resources.
As a workaround you can disable the BackgroundScan altogether. Disabling this task does not compromise the security level of the PC as the OnAccess scan guarantess the protection of the machine. If you apply this workaround simply make sure to run an OnDemand scan periodically to ensure there are no inactive & latent malicious files in the drive.
To disable the BackgroundScan simply create the following registry entry and reboot the PC:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREPanda SecurityPanda Service Host]
If you are not used to playing around with the registry, simply download and execute the .REG file in the following file:
