corrupted file in firefox

LL
I was not able to locate which file it was identified in sophos and clam with a number that followed the name of Firefox. Trinidad could be correct, it could be a false positive and I am unable to post a screen shot since it is not in the O/S Ubuntu that I am at the moment using. I had been able to remove it previously by refreshing Firefox and re-booting. Lately that did not work.
When I get back into LL I will try the first suggestion and re-set my profile.  If you look at Ubuntu`s web sight it states in the overview for desktops that it ships with maleware or virus protection, as to the details of that claim, I never followed it up.

Secure

With a built-in firewall and virus protection software, Ubuntu is one of the most secure operating systems around. And the long-term support releases give you five years of security patches and updates.
