Hello, as the title described, I think chromestera had infected my browser as it is difficult to use the browser due to this malware. Could you please assist me on this issue?

Hi,

Remove this program in bold using the Control Panel > Programs > Programs and Features...
Chromstera (HKLM-x32\...\Chromstera) (Version: 119.0.6019.0 - The Chromstera Authors)
<<<>>>

Please download the attached Fixlist.txt file to the same folder where the Farbar tool is running from.
The location is listed in the 3rd line of the FRST.txt log you have submitted.

Run FRST and click Fix only once and wait.

The Computer will restart when the fix is completed.

It will create a log (Fixlog.txt) please post it to your reply.

Please post the Fixlog.txt and let me know what problem persists.
