Possibly have an infected PC -Combofix install is a trojan, or false positive?

So, my computer the past couple days has been acting slow, even if the PC was reinstalled only a month ago and a new harddrive. My IT guy (well neighbor who works customer support for Dell)...scanned my computer with Norton 2012, MalwareBytes and Combofix...this was yesterday. Today he scanned with Tdsskiller. Norton and MalwareBytes found nothing. However, Combofix found something in C drive called "Installer.exe". Now that is important, because before I reinstalled my PC...Combofix kept repeatedly finding the file every time it was used, but I can never actually see it in the folder.

 

But, my PC is even laggier today and my IT guy (unavailable for a couple weeks) suggested I go to a tech forum and see if I can get any help. He suggested to run the scans again and again run Combofix. However, I downloaded Combofix and

 

Norton detected Combofix.exe has a trojan.adh.2...now I'm hoping this is a false positive, but is it possible that I have a nasty virus and it is infecting Combofix when I download it?

 

The other day Steam completely forgot all the settings for all my games and I had left it on over night, but it wanted to redownload visual studio files for various games and directx files. None of the games would run, either. A restart of Steam fixed it and it hasn't done it again, so it may have been a Steam thing.

 

But Youtube videos load a lot slower than usual or I have to refresh the page to get it to load, and sometimes a website doesn't load properly or some of the images on the site show up as a blank spot, and a refresh gets it to come up.

 

I'm not sure if this is really the appropriate forum to get help with that, but I have a Combofix log from yesterday, as well as a Malwarebytes log (which found nothing)...and TdssKiller found nothing, nor did Norton. I can post the Combofix log, if this is the right place to get help.

 

I'm mostly curious if a virus is infecting Combofix when I download it...do note, I got the same download my IT guy used yesterday from bleepingcomputer, the official site and the same download location. Or if Norton is seeing it as a false positive.

IMHO (expecially since your IT guy suggested addtional assistance) , it is best to refer you to the recommended forums, where a real malware expert can work with you one-on-one in real time to dig these things out. Some of our best folks here have checked them out to make sure that they are capable, and competent to deal with rootkits and other nasties. Most of them handle tricky Windows problems as well.

 





 

Just sign up for one of their free accounts--where required--and go to the forums; don't click on any of the ads! Note that some of these forums (like bleepingcomputer) require that once they begin working with you, you not consult any other sources on your infection until it's resolved--and will close your case if you do. This is important, to avoid confusion (and really bad outcomes) resulting from trying to follow several people's advice at once! LOL

 

 

Good luck, and please let us know how it turns out!
