I have an HP Pavilion dv4, 500gb memory, about 5 years old. It was working fine up til about a week ago when everything started running very slowly, at least ten times slower than the day before. Firefox kept randomly pausing every five seconds or so, programs take a long time to open, etc. I reset the system to a save point from earlier in the week. That took about 12 hours for the computer to complete, and it didn't help. I thought maybe I picked up a virus, so I tried to run a scan. Malwarebytes didn't find anything and Microsoft Security Essentials has, as of this morning, been running for about 56 hours and has scanned about 300,000 files. I don't think that should take this long. I am not computer savvy, so I looked around on the internet and some pages suggest that my hard drive needs replacing. Is there anything else it could be? I have no idea how to port my operating system and everything over onto a new hard drive and would like to avoid screwing up my computer even more.
