how to remove blue box with arrows?

Geez, after last weeks sudden appearance of the weather icon, this morning I notice all my files icons in explorer have a blue box with 2 right facing arrows. How do I remove these boxes? Win10pro 20H2 ver 19042.985
Thanks

Thanks Dalchina. Yes I am using Norton and since you mentioned Norton, a message box came up from Norton about installing a ramsomware add-on and to do a cloud backup. I did install it but can not do the backup since the allotted space is smaller than my backup size. When I get home tonight, I try what you suggested- i'm at work on my laptop. As far as a screenshot goes, how do I do that and I will need to update my system specs since all my computers are on the same win10 pro version.

thanks ghot

Two blue arrows means your files are compressed.

Open an administrative command window (cmd.exe) and check your system status:

compact /compactos:query

If system is indeed in compacted state and you don't have any free space issues and you want the utmost speed, unpack it by running:

compact /compactos:never

And afterwards: compact /u /a /i /s /exe c:\*

That command will decompress ALL FILES on your C drive.

And this command will decompress all files using NTLZ1 (NTFS compression) on your drive.

compact /u /a /i /s c:\*

Thanks all. It was Norton and I followed the above directions and they are gone. It was the style shown in Dalchina's last post, small blue box in lower left corner.
