I am no expert, but found this website to get help. My anti-virus program identified a Trojan which got on my computer. I am certain it came through IE Explorer, which I hadn't been using, but used for a particular website which would not operate through Firefox. The Trojan was located in ...AppData/LocalLow/Sun/Java/Deployment/cache and was called OpenConnection. I tried to delete Java through uninstall ,but nothing changed. I finally removed the whole cache file and deleted it from the Recycle Bin. That worked to get rid of the Trojan, but no new cache folder was repopulated. Can anyone tell me what the consequence will be? So far, I don't see any problems on my computer or browsing the internet. Thank you.
