Open that strange attachment in your Yahoo! email and your computer may be infected with a virus, a nasty piece of software that may corrupt your computer data, delete files or send your personal information to a hacker. Employ a combination of proactive protection measures and post-virus removal techniques to guard your computer against any viruses hiding in your Yahoo! Inbox.
1 Avoid opening emails from suspicious sources or with unrecognizable text in the "From" or "Subject" headings. And never open attachments that you are not expecting, even if they appear to be from a friend, without first confirming it with the sender to ensure that it is a legitimate attachment.
2 Check the top of the Yahoo! page when opening an attachment. Yahoo! employs a free virus scanner that scans all attachments when you try to open them. If you try to open an attachment with a Yahoo! virus, the website will alert you to the danger. Press "Delete" immediately.
3 Click "Deleted" in the left column of Yahoo! after deleting a virus-ridden email. A page showing your deleted emails will appear. Push the "Empty" button at the top of the page to permanently remove all of your deleted emails to prevent accidentally moving the virus back into your Inbox.
4 Run a virus scan on your computer system if you open a strange attachment and suspect that a virus got through the Yahoo! scanner. The scanner will identify and remove the virus if it has infected your machine.
