For everyone who is experiencing a virus of some kind, you must have a high quality anti-virus software installed on you PC,its a fact of online life, its not going to go away, there are new one being created each and every day, I know from bitter experience how time consuming, annoying, damaging and expensive they are ,my only advise is to buy a high quality anti-virus software, with regular (everyday) automatic check for upgrade,you can buy online from manufacture's ie Norton ( which I have) Mc Alfie etc, also
Amazon, or Ebay, you have to spend the cash but its worth it.....................Good Luck
