With Sophos are the memory resources reasonable. ?
Have been using Avira for 4 years and its real time scanner avguard.exe regularly sits at 700MB so I am ready to try something new.
Real time scanning exist in Sophos too
I see
For real-time scanning, the following options are enabled:
Scan on read
Scan on write
Scan system memory
Scan remote files
Automatically clean up malware (if clean-up fails, then deny access)
Detect malicious behavior (HIPS)
Detect network traffic to command and control servers
Block access to malicious websites
Scan downloads in progress
Detect low-reputation files
Potentially Unwanted Application (PUA) scanning
PUAs are blocked by default. Once detected you will need to either authorize the application in policy or clean up the application from the Dashboard.
Scans executable files (does not unnecessarily scan files which cannot infect a computer)
Sophos Live Protection
Like Avira this behaviour is intrusive looking at read/writes of all processes, but seems as though it could be useful.
For those suggesting Microsoft option I am not sure it had anything similar ? so I would (wrongly ?) discard it on that basis.
