All of a sudden I get 288 messages telling me that ...\Local\Mozilla\Firefox\Profiles\3va5xqqp.default\Cache\*\**\******** is a HIGH THREAT during my weekly AVAST run. THis is the paid for Internet version of Avast and I have not updated it or Firefox recently. The "*" in the code are different directories and files that are unique to each line. So there are 288 variations. Will run a boot time scan now before just deleting these. IF the boot time scan finds them as infected it will clear them out. The browser seems to have no problems. So I am really confused.. Any help will be appreciated. All of the messages are listing firefox as being infected.

I do not automatically update firefox as other addins never work until I let things settle. I ran a boot time scan and NONE of those files showed up. This is obviously an avast problem and I have sent both logs to them. Thanks.

Files in the Firefox disk cache can usually considered as harmless.

See https://support.mozilla.org/kb/Firefox+cache+file+was+infected+with+a+virus

Also your Firefox version is ten major updates behind and potentially vulnerable as a result.

Well a problem in that they make it appear worse then it actually is as the viruses/Trojans and such found in Cache is harmless unless you manually try and run them and they will get overwritten over time anyways unless you manually clear Cache.

Sometimes a recent definition update can cause false positives and another update is needed.

The majority of Extensions that were made compatible for Firefox 10.0 and newer should still work fine in Firefox 21.0 unless that use a binary or are version specific for a different reason. The full Themes (not persons wallpaper) of course usually needs a update.

It is usually Roboform that lags behind that I totally depend on. I do not know how many times it will take a week or so for them to get their updates together so I turned auto update off... And I am totally dependent on Roboform.

On another note besides flagging 288 profiles it always sqwaks about older zipped install files but just says they are password protected which they are not..

BUT THE JOKE is in the report I sent them, over 500 lines 19 lines resulted in squawks against AVAST ITSELF. Unreadable usually. THanks for the help. I Sent it into avast and asked they why their own files are actually flagged as well!
