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.
Rising's free firewall, Avira's free AV (consistantly rated the top AV), Norton Antibot for HIPS, SuperAntispyware ($20 for a lifetime license) and Winpatrol Free.
Put up a hardware NAT/SPI router and you're basically bulletproof.
I don't use 3rd party software firewalls, I just make sure any/all PCs are behind a NAT router. Brief trips to open wireless with my laptop such as a coffee shop, my not having the Administrator account blank, and putting up the Windows firewall..is good enough for me.
Esets NOD32 is just their antivirus product, it's not an internet security suite. Eset does however, make a combo antivirus/software firewall suite called "ESS".
