Repeatedly being infected and getting BSOD - possibly related
Hello, first time poster but I will try to be as descriptive as I can with my problem.
I'm having two issues with my work pc and I'm not sure if they are related to one another but after various tests I believe they are. First, I am repeatedly getting an F4 blue screen error on my Windows 7 x64 pc. The blue screen seems to occur randomly, meaning there's never any one thing I'm doing when it happens. It's happened when no programs were open, and also when quite a few programs are open. After doing some research, most users have formatted their hard drives and reloaded Windows to fix this problem. However that method has not worked for me. I have formatted and reloaded Windows probably a dozen times since this problem started and the blue screen continues to occur.
The second item I need to note is after I get a blue screen, I almost always get infected with some type of virus. I've had multiple types of infections occur including malicious executables appearing in my startup folder which cause Internet Explorer windows to pop up upon logging in, and I've had malicious executables show up in my System32 folder, and I've also had windows processes like taskmgr.exe become infected.
A few things that I should note:
Since this problem occurs repeatedly even after formatting and loading Windows 7, I have already tried using a completely different pc and the blue screen/infection still occurs. At my work place, we use roaming profiles on our network so our first thought was since I tried different pc's and the problems still occur that maybe my profile was infected. We then deleted my profile and created a new one yet the problem remains. I also seem to be the only person having these issues so it's not widespread, it's only me.
Whenever I get the F4 blue screen, programs installed on my pc stop working correctly. Specifically, Microsoft Outlook will no longer open and it always prompts me to re-enter my product key when I already did so. Other strange errors like this occur and I believe it's from the F4 blue screen.
We use ESET as our anti-virus program and it never detects infections on my pc. I've tried Malwarebytes and that will usually pick up malicious executables but it never prevents new ones from getting onto my pc.
Since my last Windows reload, my pc hasn't blue screened so I don't have a recent minidump to share but I am definitely infected. Right now it is off the network and sitting idle.
I personally have two theories on what is happening. Either a virus is continuously infecting my pc and causing the blue screens, or something else is bringing about the blue screen and causing me to become more susceptible to viruses.
I know this is a lot to take in but any help is very much appreciated!
