My wife makes a living on ebay.She does hundreds of transactions a month and you would be amazed at the FAKE emails she gets from ebay.There are ALOT of scammers out there.We have had fake emails from paypal & ebay requesting information they should already have-a dead give away.Anti-virus protection is a whole nother story.There are so many hackers,spyware & viruses out there its hard to keep up.I know that any antivirus program you get off the internet is old tech and is crap if you need real protection.The 2007 macafee antivirus propram that you BUY is so big that if your computer is 3 years old or older the program will shut it down.We use norton and have had zero problems but these are progams you have to buy and have to be repurchased and updated every year.I have a Dell that we bought in 2004 and Ive had to have 2 more memory sticks added so it can keep up.It now has 5 times the memory capacity it had new.The sad thing is this thing was "the $hit" when I bought it......
