I don't open anything that isn't sent by my friends. My friends all know not to send me attachments. instead they send me forwards. that way I don't open anything that has a virus. Top that off my yahoo and aol email accounts both have virus protection. Yahoo scans and WILL NOT allow an email with a virus to be opened before it is cleaned. for example in my bulk file I keep getting emails that say things like "re: and a number" those ALWAYS contain a virus and cannot be opened. I also recieve "your account is overdrawn please take steps now to correct this" in the subject line. Well I deal directly with my bank across the street from me and they know why my account gets overdrawn when it does and I have overdraft protection on my account so I already know those type emails are open and get virus or spyware trouble. Basically if the sender isn't on my address book I don't even try to open the email to see what they want me to open as an attachment. I also use McAfee virus, spyware, firewall and spam protection. McAfee is great notifies me right away when it finds anything and runs automatic scans weekly and I can also manually acitivate a scan on ALL my computer files. It also keeps track of any other computers trying to hack into my computer, blocks and locates the hacker so that I can decide if I know that person and allow them access or not.
