Probable Maleware infection?

[pelgv]

Hello,

I would like to know if someone could help me or give me some advice.

Recently I started having several issues with my Windows 7 installation. I have Malewarebyes installed and I used to have Kaspersky. I tracked a lot of the issues to Kaspersky and after a couple of talkings with the support guys I gave up, uninstalled Kaspersky and installed Bitdefender. 

Windows started to reboot extremly slowly. It would take 3 to 5 min to start. Then it would start and Malewarebytes would tell me that the web protection is disabled, and Bitdefender would tell me that the firewall was disabled too. Windows 7 would also start without Aero theme. 

I went into safe mode and scanned my computer with Malewarebytes and nothing was found. Scanned my computer using the Bitdefender in safe mode and did not found anything. Rebooted several times in the process. At some point when I restarted, I had no network, an error stating that log services was off, and when I investigated further, I found that EVERY service in windows was disabled. 

After setting all services to Automatic, I restarted again, and I had access to internet, but still things are not normal.

 

Any advice?

 

Thanks

Hello Ron,

Thanks for the reply. 

It will take a while to finish scanning with the Sophos tool, so I am posing steps 1, 2 and 3. Also some more information.

When you asked me to reboot my computer, it installed some Windows updates. It took a while to install and then I had to reboot two times. After the second time, I was able to log into windows, although that also took a while (2-3 min). When I logged in, the desktop looked normal, ie. Aero for windows was enabled and I did not get any error of any kind. 

I ran step 1 and 2, and I had to reboot on step 2. It again took a while to reboot and log in. In total maybe around 3-5min. When I logged back again, Aero was disabled, I got a Windows Service error and my antivirus firewall was again disabled (see "Weird Desktop with windows service.png")

 

I do not know if you prefer the logs as attachments or text, but I am attaching them now. On step 1, I ran the tool with the antivirus enabled, so I disabled the antivirus and ran it again. 

 

I might have to wait until tomorrow to continue as I suspect the Sophos will take A LONG time (I have almost 2TB on over 600000 1 million files). 

 

Thanks a lot,

Pablo

It's possible if you don't have the very latest installation of Bitdefender that there may be some conflict with Malwarebytes. Bitdefender did fix the issue a few months ago so as long as you have the latest version that should not be an issue.

The JRT and AdwCleaner did not find much of any issue. Post back the Sophos when you can and the FRST and Addition logs as attachments when ready.

Thank you

Ron

Hello Ron,

Thanks for your response.

I believe that I have the latest Bitdefender install as I switched from Kaspersky a few weeks ago... I will check and update if necesary anyway.

Sophos did not found anything, see attached picture.

Attached also the FRST scan. By the way, the Maleware protection module of Bitdefender started complaining about FRST and blocking it from looking into folders or something like that... I had to disable it.

As suspected, the computer shows no real signs of being infected. If the computer is still running very slow it could possibly be the hard drive is slowing. Would be best to run some diagnostic software to check the hard drive status.

You can use the following tool from Microsoft to help determine what's running and causing an issue.

Could also possibly use

At this time the computer does not appear to be infected.
