Not sure if my new PC is infected but need to know... Help please! :-)

Greetings All!

 

A little background... I purchased a later model Dell Vostro 270 off eBay and got it last Wednesday (04/09/14). The seller said he had reformated the HDD and reloaded the Win 7 pr OS. When I got the PC the only icon on the desktop was a recycle ben icon. It did indeed look like a fresh OS install, but I'm no expert. The first thing I did was to see if I could get on the internet... yes; next, I downloaded the free AVG 2014 antivirus (which is what I had on my old PC); next, I downloaded Firefox browser; next, I uploaded MS Office 2007 and my Epson printer software/drivers. So far so good, and working like a charm.

 

I decided to go a little further on the safety and security thing and downloaded the latested edition of Malewarebites. This is where things went badly wrong. The first Malewarebites scan flagged some files it said were bad... I thought maybe it was undeleted cookies or something. Malewarebites deleted the bad files and ask me to restart my PC. After restart, I could not get on the internet, in Firefox or IE. I would get an error message that said something like "proxy server not recognising user" or something like that. In my panic, I uninstalled Malewarebites, because I thought that is what caused the problem. Then, I tried several attempts at system restore, to no avail evidnetly. I kept getting this error message that I may have to disable my anti virus to get the system restor to work. I figured out how to disable the AVG and tried the system restore again. I'm not sure if it ever worked, but I still could not get on the internet.

 

I used my laptop to connect to the internet and googled the problem. I read about someone with the same issue using the combofix program so I tried that, and it worked (I downloaded the Combofix program on to a flash drive using my lap top and then ran in on my new PC from the flashdrive). I was once again able to get on the internet. So, now the questions... Was my PC infected to start with? Why didn't AVG find it, if it was? I will add that the current AVG scans say there are no current threats, though it did flag and delete what it called a trojan after I ran the Combofox program.

 

Is my PC clean now and is it safe to log on to my bank account? At this point, I'm not sure what was wrong in the first place, what happend, and what to do now...

 

I have ran the DDS logs as requested in another thread I started (apparently in the wrong thread) and will post them here. I also have the Combofix log but someone said I could not post it in the other forum. 

 

Any help would be much appreciated!

 

Rick

 

P.S. Sorry, I just read that I shouldn't post the "attach.txt" log unless specifically asked to, so I removed it until I'm asked to post it...

Okay, folks, since the computer was basically new-to-me, and did not have any of my files/data on it yet, I decide to do a clean re-install of Windows 7 for my own peace of mind. I had to get up the courage to do it, since I've never done it before.

 

It took a while and I had to reload the drivers and utilities manually, more or less (CD was not a plug-n-play), and then it downloaded 150 windows updates, (which took about 2 hours) I think I'm out of the woods. I decided to go with the free edition of Microsoft Security Eccentials antivirus rather than AVG. Not sure which one it the best.

 

To the moderators... you can close or delet this thread.

 

Thanks,

 

Rick
