Internet explorer opens "on it's own"

For the past several days, I’ve been finding several instances of IE opening on my PC, often while the computer is in sleep mode. Usually nothing opens but every once in a while this page loads:

link removed

I don’t use IE at all, I mostly use Firefox (28) and occasionally Chrome.
current Avast version 1404040 last updated 4+4+14

Not only is this annoying but it’s very disconcerting with Avast running in the background. :-[

Good day,

Please go [u]Here[/u] and attach MBAM, OTL & aswMBR. After that, I can get a remover.

also, break that link. It is extremely unsafe and needs to be removed ASAP.

Post reported to Mod for link removal. Polonus has been asked to look at it.

Note: With that link loading, you are most likely currently infected.

I see you edited, are you still with us?
