Does Network Shield module affect browsing speed or system memory usage?
If you disable Network Shield you won’t improve performance. It protects the computer at driver level (no resources are used).
Now the Web Shield is another thing that filters the web traffic and the virus will be detected before the file is saved to the disk. As far as I know the network shield does NOT use resources while the web shield uses some resources but does NOT slow down your internet speed.
Any impact on browsing with the Network Shield (negligible) and Web Shield (minimal), the resources are also minimal. When taken against the protection they provide, no contest keep them both enabled.
I use a dial-up connect and see No Noticeable impact on browsing.
OK. Thanks for information!
