I have spotted a couple of messages referring to accessing l33.ko0ppol.biz and a11.JE34KE5.net. Having done various searches on these I have found a web site that refers to worm_icrbot.lc as being the problem. Searching Norton/Symantec finds nothing on this.
I don't want to download lots of different malware removers as all seem to find something different, but I do want to get my PC properly cleaned up. I am quite happy to pay for my software/advice once I can find a specific resolution to this one.
I have not contacted any other sites but this one - I like the look and feel of this and hope that you can help me.
