Notice from USPS about package delivery
by Harv - 7/26/12 7:04 PM
Out of curiosity, I foolishly clicked on an email message allegedly from the USPS regarding confirmation of delivery [according to the subject line]. When I clicked on the link, a distorted image with writing appeared that claimed the post office could not deliver my package, because the address was unknown. Since I hadn't mailed a package, it suddenly dawned on me that this was a scam and that I might have comprised my computer.
I did a full scan on Malwarebytes and Microsoft Security
Essentials and both showed no viruses or malware. What other steps should I take to ensure that my computer is clean?
OS is Windows 7 Home Premium [X64], Comodo Firewall Free Version and Firefox 14.0.1 and Microsoft IE9.
