I was working on my computer in February when it stoped working and kept flashing a message that my anti-virus was not working and someone was trying to steal my credit card numbers and other information I tried and tried until I got rid of it as I was sure my anti-virus was working about 2 weeks later it happened again and this time nothing worked and I could not work on my computer so i got scared and paid for it it just stoped flashing and I did not receive any conformation or anything now on my credit card bill is a charge for $139.00 from worldwidesoft.com and the adress is Russia.
