External HDD causing problems

Hokay. So... I've never seen a problem like this before.

My external hard disk drive is http://www.amazon.co.uk/dp/B009HXWTGO/ref=pe_385721_37986871_pe_364681_36330151_item

For some reason if I start my PC with this connected it will slow down the startup time by ~10 seconds. Even weirder, however, is that I have problems accessing explorer.exe.

If I start the PC without it connected these problems disappear. However, I cannot access my Mozilla firefox profiles (And thus cannot access firefox,) if I do not have this connected anymore.

I haven't a damned clue why any of this is the case. All I know is that this HDD is connected to the problems. Anyone got any ideas?

    I can't see anything out of the ordinary and McAfee picks up nothing. I tried starting it in safe mode but had no luck.
  3. Decided I was going to reinstall windows...

    So I got another external HDD to go and save my important files onto.

    For some reason this one - which is a completely different make to the one specified above, - also solves the problem. I'm quite confused now but I believe a virus is the only thing that makes any logical sense.
  4. Avast might pick it up or you can get malwarebytes to see if that's the cause. How old is this affected drive? For this reason i prefer buying internal hard drives and just get an enclosure so you can easily pull out the drive to diagnose the drive itself to see if maybe the drive itself is having problems running correctly.

    The external HDDs are new but my windows is on an internal SSD that is about 1/1.5 years old. I also have firefox on an internal HDD that is about the same age as the SSD. I don't think it's a hardware failure. I've checked for suchlike already. I'll try malwarebytes whilst transferring files to my external HDDs. If I find nothing then I'll just wipe everything and reinstall windows. I might try resetting the device software for USBs before that. One of those should fix it. Was just curious as to whether anyone had seen a similar problem.
