The problem with my Yahoo email is that I cannot view any email that is older than about one month. When I do a search in my inbox, I get the results, but when I try to open any email older than one month, I get this message: "There appears to be a problem loading the email." A retry button appears, but I still cannot open the mail. I first noticed this problem about a month ago, and it is getting worse, as I cannot view mail from 3 days ago! Trying to open the mail later does not solve the problem.
I had problems with my Yahoo email account about a year ago. It kept getting hacked and was sending out spam. I could see the spam being sent out in my "Sent" folder.
I regularly run Spybot, AdAware and Avira Antivirus. I run Spybot about once a week. I run AdAware about once a month. I run Avira scans about once a month.
I also get an error saying something about D: Autorun has been cancelled. I get this error about once a day. I know this is not a good thing.
