Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I would reccomend doing a full scan for spyware and viruses. For spyware use Adaware and Spybot S&D. AVG is good antivirus program to try. Also make sure windows updates are all complete. Once this is done and if the problem is still there we can start to look at other problem sourses.
