What could be keeping my antivirus program from working?

I normally use Microsoft Security Essentials for my antivirus program. But the other day when I tried to update the definitions it would not update. It kept freezing up. I tried uninstalling the program and reinstalling it, but it still wouldn't update the definitions.

So I uninstalled it again and installed Avast and it wouldn't scan. It also froze up during the scan and wouldn't go past 0%.

Thinking I might have an infection, I scanned my computer with malewarebytes, superantispyware, esetonlinescanner, and housecalllauncher. They don't find anything. And I haven't noticed any other computer problems so I'm thinking it's probably not an infection.

Someone also told me to try creating another administrator account on my computer (windows 7) an running my antivirus program from there. But, it still wouldn't work.

Any ideas what could be keeping my antivirus programs from working? (I only have one of them installed at a time).

Please download and save FRST 64bit or FRST 32 bit to your Desktop see what this tells us.

http://download.bleepingcomputer.com/farbar/FRST.exe

http://download.bleepingcomputer.com/farbar/FRST64.exe

Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
Make sure that Addition option is checked.
Press Scan button.
It will produce a log called FRST.txt in the same directory the tool is run from.
Please copy and paste log back .
The first time the tool is run it generates another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe).

Hi Kuurt,

Malwarebytes and Eset are pretty good at finding infections.
you could try Farbar
Farbar Recovery Scan Tool Download

I'd be more inclined to run, from an elevated command mode,
sfc /scannow
And
KB947821 (SURT)

post the logs from them please, in built zip (compressed)
(c >> windows >> logs >> CBS ....top text file and SURT at the bottom)

Hi Kuurt,

Hi Kuurt,

Thanks for that i was hoping to see a vbs script error, but its clear

Do you still have your original install discs??
(not a problem if you dont)

please run/post the results of the other 2 progs i mentioned earlier.
They may clear your problem, if not they may point me in the right direction.

Not sure if the torrents you have are causng the problem!!,
but you do appear to have some strange firewall rules as well.

I can see its a pretty old system but i DONT think its a hardware problem

If the 2 progs fail to clear the problem we may be looking at a repair install -- NO LOSS of personal data.


Roy

2.30AM here bed time

I don't have the install disk, my brothers got it at the moment.

What other 2 progs are you talking about? The ones I already posted?

Hi Kuurt,

in post no 3

sfc /scannow
KB947821.

Has this machine previously been infected??

Roy
