My computer knowledge is pretty basic, but I came across this site and have been really impressed with the amount of information and help available here.
I am posting this message after spending hours trying to remove a virus. I'm hoping someone has an idea what it is and can suggest how I can get rid of it.
I have an Acer laptop which runs on Vista Home 32-bit.
General description of the problem.
The virus affects my Firefox browser first of all. I have the lastest version of the browser. It then spreads and starts to affect Windows.
How it appears and affects the computer.
Virus usually appears first of all by making Firefox stall. A small grey circle appears under the tip of the cursor as I move it around Firefox. There's a black spiral at the centre of the grey circle. Firefox starts to freeze and stops responding when I try to shut it down.
At this point Windows task bar (at bottom of page) disappears and so do the icons and everything on the desktop - but Firefox stays there just frozen.
Soon aftter this it causes Windows to stop working and the whole computer stops responding. I normally force a shutdown at that point. It restarts well enough and can run fine for days at a time and then it comes back randomly.
I think I got infected when my Avast anti-virus expired. I haven't been able to take a screen grab of the problem as virus renders laptop unusable when it appears.
I have so far run a number of programs to try to remove it, including Malwarebytes, Kingsoft anti-virus, Avast Pro (which I subscribe to), SuperAntiSpyware and Windows Defender and I've run a scan using Hitman Pro. None of them have picked up the problem.
I'd be very grateful for any help or advice you can give.
