We've recently been having problems with redirects when clicking the links of search results in our browsers (IE and Firefox). We tried a few different virus scans and nothing was able to find it. However, we did realize that Microsoft Security Essentials would not run when we clicked the executable. So, with advice from these forums, we changed the name and it ran without issue. It immediately found "Exploit:Java/CVE-2013-1493". Now that we had a name, we were able to do some more research on it and realized it might be a good idea to disable Java in both browsers and only enable it when needed. But, my questions to you is, what is "Exploit:Java/CVE-2013-1493" exactly? Is it a file? Or, just an exploit? What did Microsoft Security Essentials remove, exactly? Are there going to be other remnants of this scattered around the computer? I'd really like to know more about how this works. It seems like any news articles out there just focus on the fact that it's a Java exploit, but I don't understand how it could cause redirects in my browser.
