computer help please

Hi, I had a trojan in April that I got help here cleaning up. Computer has been somewhat slow lately, but not alarmingly so. Today my hubby came and got me telling me the puter crashed and had started recovery. When recovered I had to re load Mcafee, MS office, my printer. None of my pictures or documents appeared to be in the computer, but I can do searches and find the files - so my stuff is on this computer somewhere. I'm worried I may be re-infected or infected with something else. I don't know what to do or where to start. Please help!

Take a read through this and then start a fresh thread in this forum and post a HJT log, and a brief description of your problem, and somebody will be along as soon as.
Helpers look for posts with zero replies which is why you need to start afresh and why i'll lock this one.
