My first thought... If you're downloading files using a P2P file-sharing program, the best way to prevent such problems is to STOP using P2P.. It's one of the major ways for such malware to get passed around..
Second... If the problem is with downloaded e-mail items.. NEVER open e-mail messages from unknown sources and even from known sources, make sure to scan attachments before opening them.. Simply delete them BEFORE opening them when they come from an unknown source.. Remember what curiosity did to the cat...
Next, never download files from untrusted websites.. A free program such as McAfee's SiteAdvisor might help with identifying which sites are not trustworthy.
Next, Norton's background scanner already detects viruses and some spyware during the download process to your e-mail program or when you download a file to your hard drive.. There's not much else you can do other than manually performing a RIGHT click scan once the file is downloaded to the computer.
Hope this helps.
Is there a way to scan a file with Nortons BEFORE downloading it?
I have recently had bad luck trying to download items, and after downloading Nortons catches it, but is there a way to catch it before it is even on my computer, or while it is downloading?
Thanks so much!
