I like to press scan on the hp7520 & be able to see my pc listed & wirelessly then press PDF file. After the scan a pdf file pops up on my pc screen for me to save & email. Did this for a year and then my windows 7 had a virus that required a paid third party vendor helped me fix. Afterwards my HP 7520 no longer scans from printer directly to pc even though when I press Other I see the name of my pc listed. But when I press it I get a message 'computer not found'. How to reconfigure to scan wirelessly from hp7520 directly to my pc? Thanks.
