I found a post on another part of the community DB by someone who, like me was really upset. "ex brit" recommended 'malware bytes anti malware'. It is a free, fast download. It found 91 infections on my computer (McAfee had found four?!) After the scan, it offered to remove them. I held my breath and clicked the button to remove them. I haven't run any scans, but it said they were removed. Yayy!! I hope this helps anyone that is having the same problem I am.
Discussion moved from Community Help to Home User Assistance in Malware Discussions as a more appropriate spot. Community Help is for people having problems with the forums.
I'm glad it's OK now and thanks for posting.
