I think i have a keylogger but nothing found

I received a notification that my yahoo account had been compromised so after changing the password, I performed a boot time scan with avast and found the following issues:
OtherMalware-gen
HTMLDownloader-F[Trj]
JSownloader-ANV[Trj]
Win32:Mirc-Z[PUP]

I am worried that I may have had (or still have) a keylogger. I realized that my firewall had been turned off as well (not by me) and I had to reboot to turn it back on. I quarantined the offending files and then followed the instructions posted here to first prepare my computer (including removing java, deleting those quarantined files, etc) and then I ran the various scan tools.

SuperAntiSpyware found nothing. I can't find any tools specifically for JS:downloader-ANV cleaning and admittedly didn't look for specific tools for the other viruses yet (though I did look through your list of add/remove software items).

I am attaching the log files of everything else.
Is there a probability that there may still be an active keylogger on my system?

/I apologize for asking for help as a first time poster :noob

 

BTW: The yahoo notification was not in an email, but instead, when i was logging in, it said it had been compromised and to change my password. I checked the url and it looked legit.

 

Forgot to mention that I am running windows 7 64 bit but that probably shows up in the logs anyway, right?

 

Welcome to Major Geeks!

I will be reviewing your logs. Please be patient as there is a lot of information to review

 

No malware in your logs so far. Let's do a couple more scans.

Goto the below link and follow the instructions for running TDSSKiller from Kaspersky

• TDSSkiller - How to run

Be sure to attach your log from TDSSKiller

Also please also download MBRCheck to your desktop

• Double click MBRCheck.exe to run (vista and Win 7 right click and select Run as Administrator)
• It will show a Black screen with some information that will contain either the below line if no problem is found:
  • Done! Press ENTER to exit...
• Or you will see more information like below if a problem is found:
  • Found non-standard or infected MBR.
  • Enter 'Y' and hit ENTER for more options, or 'N' to exit:
• Either way, just choose to exit the program at this point since we want to see only the scan results to begin with.
• MBRCheck will create a log named similar to MBRCheck_07.16.10_00.32.33.txt which is random based on date and time.
• Attach this log to your next message. (See: HOW TO: Attach Items To Your Post )

 

Looks clean. no warning messages. I am a little spooked by some processes called ActivIdentity and Andrea filters APO access service but they may be related to something I installed since I last looked at my processes.

Attached is the log from Kaspersky but I can't find the one for the MBRCheck in the folder where I ran the program or in the C drive.

 

MBRCheck.txt should be on your Desktop. You have so many desktop icons though I can see why it would be hard to find it :-D
