HELP! A year ago my computer crashed because of a virus. Dell fixed it remotely, cost $140 and another $80 for McAfee. Warranty expired 3/7. Did not renew it. 3/26 I get a virus that makes my Yahoo email impossible to read. Another $140 to dell and they'll fix it. Coincidence or scam? Ideas anyone? Must I rely on Dell again or does someone know somebody who could fix it for less??? Everything else on my computer seems ok.
