I just got this message when Avast updated, on 3 sites Joomla 1.5

I did have that module, which I chgd, but I am still getting that error on the one site. I tried to restore older version, made the chg and still get message.

Must be another module that has problems. Can we get a better definition of the file that has the problem instead of “|{gzip}” It would help a lot.
