Spyder pausing/lagging for about 8 seconds before running inline

Problem Description

2 week following a fresh install of Anaconda on new PC, Spyder console started pausing for several seconds before returning results of executed code.

For example: In console I type in “1+1” and hit enter I get back “2” after about 5 seconds.

If I hit the “stop the current command” button I get the results back immediately. If I run the same script/code from python in windows cmd or in Atom it runs as expected.

I have tried reboot, killing nonessential processes, reinstalling Anaconda, reinstalling python and Spyder only with no success.

What steps will reproduce the problem?

1. Running code in console with any level of complexity - example “1+1”
2. Running code using run file button or F5
3. Running one line of code from file or F9

What is the expected output? What do you see instead?

I expect output. I see 5 second lag before output

Not sure if replying here works. Using Windows’ default antivirus fixed the issue for me. Sorry for forgetting to update this topic.

I have exactly the same issue with Spyder lagging for up to 20 seconds or so. Using F5 key or pressing the Play-Button results in the lag. iPython-console and everything else works fine.

Yes, They updated my Dell encryption software which helped a bit and when we disabled Symantec the lagging was greatly improved. Obviously that was just a test and we can’t leave that feature off so when I have time I will delete my windows profile and create a new one. Thanks again!
