How do i check for trojans or other hidden malware

Looks like no intervention was needed by the end user, though I jumped the gun when I first read about this. Both Mozilla and Google apparently no longer trust China based CNNIC issued certificates. Needless to say, stresses the importance of keeping browsers updated.

You can read the details here Mozilla's Security Blog Distrusting New CNNIC Certificates.

Thank you all for the responses. I am feeling a little better about my protection and the integrity of my system but will keep an eye out for anything funny happening.
Thanks again.

You should be fine. You have among top rated AV McAfee, now Intel Security, or Kaspersky, along with top rated secondary scanner Malwarebytes installed. As long as they are all kept updated, along with your browser, should be no problems.

You could add a few more layers of security. I tend to go overboard, and add the free EMET, a keyboard encryption app, and even a custom app that monitors key files such as the Hosts file for changes, though keep mine locked, which doesn't insure it cannot be changed.

AFAIK, nothing has been able to breach beyond the browser or AV, though Malwarebytes occasionally detects browser adaware.

EMET does on rare instances flag questionable server certificates. Yahoo Mail being the latest.

I did block one China based certificate authority from my browsers, as they were apparently permitting intermediate certificates from a subsidiary without adequate authentication, which could be used to spoof identity of legitimate websites. A user could be led to believe they were on a legit secured site, when in fact, a Man-In-The-Middle(MiTM) could be stealing their personal data. Breaks down the whole security trust system.

I just found out that my wireless router didn't have the encryption turned on and I was running on an open network. I run superantispyware and malware bytes every night and I normally doesn't find anything. I am worried that maybe someone saw that my network was open and installed something malicious on my machine. Is there anything that will root out a trojan or other malicious software (like key tracking)?
Would resetting the machine back to factory settings (like it was a brand new machine just out of the factory) remove anything malicious?
Any suggestions would be appreciated.

Pretty unlikely anyone would bother to install malware on your system. Most likely, anyone spotting your open access point would just be trying to use it if they needed to. What I might worry about is what they downloaded .... pornography .... or illegal music. Having that stuff come through your network could become very problematic. Chances are it isn't though. The odds are with you that you have no problem.

Well.. if the mal-ware is alrady there you may find it very hard.. There is at least ONE program that can do it (MalWare Bytes) but you may need to use the stealth versions and that is a tough job.

Take computer to Staples..They can do it for you..(By the way that is the program they use) They have two levels of cleaning.. From time to time the first level (Detection and some cleaning) is free..

Oh.. they did trash a few printer drivers on me.. So be sure to mention that to them "Please do not mess up my printer drivers".

Mr.Wizard,

Thanks for the encouraging words about being on safe ground and not needing to reset my computer to factory specs. Wasn't looking forward to doing that.

You can down load an anti key logger protection software
And you are all ready doing a nightly check
If the software is up-to-date and it hasn't found anything
I think you are probably on safe ground
Yes if you made factory restore discs, you could reinstall your Windows system for a new pc start up
But I don't think that is needed at this point
