If the "message comes up saying that a virus exists and therefore you cannot open this file." is coming from McAfee then the attachment probably HAS a virus in it which would mean that McAfee is doing it's job.
Since last week, I have been unable to open Excel and Word attachments in Hotmail. When I try to download a file, a message comes up saying that a virus exists and therefore you cannot open this file. I ran McAfee, and it did not not detect any viruses. Could someone help me understand what may be going on, and how I fix this problem? Also, the problem seems to be intermittent - there is the odd time when the file will open, but most of the time the same file will not open.
