Thanks for the replies. I looked at Eligius and it flagged my Anti-Virus as a malicious website. Ghash came up fine, so I think i'll use it. Their website looks much better than Slush's pool. Thanks for the info, I'll close this thread.
It is probably a false positive, eligus is operated by a trusted person of this community. Ghash.io actually had some issues last time I used it and had to switch to eligus. And antminer s3 are not easy to have ROI, think twice before buying.
