Win 7 pro 64 bit OS, Firefox browser, system "stable" for 3 years, or as "stable" as windows ever gets. My malware tool "Super Anti Spyware" license is expiring. Trying to update, firefox flags the website & gives a warning about a security risk if license renewal proceeds. I like the SAS tool, it consistently finds more problems than any other. A Malware Bytes scan that is clean can easily show a dozen cookies and Trojans when scanned with SAS. I have been successfully using the tool for over a year without problems. Yet I am reticent to ignore the warning. What do you think ? I have about a week to decide on a course of action.
