[Infected by PUP.Optional.Legacy and cannot get rid of it]

Dear Ron,

thank you very much for your prompt response.

Unfortunately, I do not seem to be able to access the same chrome sync property page as in the post you mentioned. Maybe because of a Chrome update? For example, trying to access "chrome://settings/syncSetup" redirects me to chrome://settings/people.

Thank you for your help.

[Infected by PUP.Optional.Legacy and cannot get rid of it]

Dear Malwarebytes Forum,

I have found a few topics of discussion in this forum which share my same problem. However, it seems the fix needs to be dealt on an individual basis, so I opened this new Topic.

In synthesis, I got infected by the PUP.Optional.Legacy adWare. The only program able to detect it seems to be AdwCleaner. However, even after deleting it, it eventually comes back. I downloaded FRST but it is never able to detect the adware. 

I attach log files for AdwCleaner and FRST. I currently just finished using AdwCleaner to delete the adware. Now both Adwcleaner and FRST cannot detect anything. However, the adware will come up again in a few hours (as it happened many times before) or after a computer restart.

May I please ask for your assistance in dealing with this problem?

Thank you very much for your assistance.
