I wasn't terribly concerned with it, as the possibility exists that I changed a setting somewhere, while going through the lengthy process of cleaning up the trojan mess. I seem to recall that happening but not sure. Tried to keep track of everything, but didn't remember to write every detail. If I did change it purposely, it was in hopes that it would stop windows from automatically directing to IE, when attempting to use a "contact us" link on various webpages. However, I have no idea what program's setting I may have used to do that.
The only other (very minor) off thing, since going through the trojan removal, was that the noise that accompanies incoming facebook IM's sounds static-like. (All other sounds/ music/ videos have been normal).
But now there is a more pressing concern. I am unable to install an important windows update. Security update for Microsoft.NET Framework 1.1 SP1 on Windows XP, Vista, and Widows server 2008 x 86 (KB2742597). When I try, I get Error 643 and I cannot click "get help with this error" because the link just auto-opens the blank IE page. I didn't even realize it that it's actually failed to install for several months. So, now I'm pretty concerned about the security of my computer.
I run spybot, malwarebytes, ccleaner, & super anti-spyware on a fairly regular basis and use Microsoft Security Essentials.....it has all come up clean since you guys helped me remove the trojan. The most recent thing I've changed was I uninstalled Java & reinstalled when the patch was released, (but keeping it disabled in Firefox, for now).
Can/should I uninstall and reinstall internet explorer?
Also, just realized I never removed combofix so I came to these forums to read how to do it. It advised to wait to remove until you are sure the computer is running properly, so I figured it was probably time to come back and ask for some advice.
I'm not sure where to begin...and don't want to make anything worse
