I am currently using Avast 8, and I run a Malewarebytes scan 2-3 times a week, and run Trend Micro House-Call scan and Avira bootable CD about every 6 weeks (I might try some of the other bootable ones like Kaspersky etc, too.) I am reluctant to use a third-party firewall because I have had no problems in the past and I am afraid of conflicts and problems with games/system etc. In other words, I am worried a third party firewall would presents more problems than it solves. Only reason I would be interested in a firewall is to prevent keylogger type stuff. I do online banking and investment stuff routinely and worried about that to a degree but it seems chances are remote since I am cautious and do not do an risky stuff on internet and never use disks or USB memory stuff of others. Also, before I log into any banks or brokerages, I do a full scan with Malewarebytes. Should that detect keyloggers? Am I okay with Windows 7 firewall? Any other non-firewall programs to use to scan for them?
