Google Chrome Cache Threat

I use Google Chrome as my primary browser. I have never had problems with any threats in the past until recently. Lately, Sophos has been "detecting" threats in the cache and they have to be cleaned up manually. Although I have had a mac for about two years, I am still learning the tricks when things like this happen. The file names are f_00b644 etc. I dont know whats causing these or where they are coming from. Any help on where to look to delete them, or what they are would be great. If this has been covered before, I'm sorry. Thank you.

I can't say positively, but they're likely Windows threats that you've picked up in the Chrome browser cache. Just empty the cache more often or set Chrome to empty it each time you exit.
