Windows 7: What system Security software do you use?

kaspersky ESET-nod32 MSE Bitdefender F-Secure Antivirus PC-cillin McAfee Virusscan Norton AntiVirus AVG Anti-Virus etrust EZ AntiVirus Norman Virus Control

I use Microsoft Security Essentials 4 along with the occasional scan with Malwarebytes Antimalware. I also use Windows Firewall and common sense
Also, NEVER have more than 1 realtime antivirus software on your pc. It looks like you have several. You need to remove all except Microsoft Security Essentials. Sometimes they can conflict and reduce your protection.

Avast! Free Antivirus, ans Malwarebytes ; + obviously common sense that windude99 prescribed

Sandboxie - NIS 2012 - MBAM Pro - Norton DNS IP settings.

Ditto plus Comodo Free Firewall.

I don't search for and use any pirated software, and I don't download music and movies
I leave UAC enabled and use the Windows firewall
I run Microsoft Security Essentials
I occasionally scan with MalwareBytes
I run Spyware Blaster from time to time (Although I don't think it really does anything)

I don't click links on websites or facebook for free stuff, look at this outrageous photo, click to see how embarrased this person is, etc.

I use comodo internet security suite. a friend of mine recommended it and so far it seems to be good.

Microsoft Security Essentials and Malwarebytes Free - so far so good - but then I am very careful with what I download and which sites I visit.

Malware Defender.
