Murof Trojan...ugh...hate those spammers!!
For the anti-virus, try AVG's free version: http://free.avg.com/
Windows Malicious Software Removal Tool (KB890830) is supposed to be very good but (knock on wood) I haven't used it personally:
Finally, try MyNetWatchman's "SecCheck" tool. He's a security researcher that offers this real-time tool for free. It keeps his data current and compares your system to his current standard based on many other systems. He does not collect any personally identifiable information, and all his data is aggregated. I vouch for his integrity.
As for that Hero you posted, I'm afraid I would fail miserably at that culture test! Let's hear from some folks here who know those things...
PS - Psyfalcon's suggestion for Avast is good, too. I've used them both; liked AVG's interface a bit better but I think their A/V definitions are about equally good.
PPS - Firefox users, consider NoScript
plugin to prevent scripts from running without your permission. They're a common drive-by attack vector. It's saved my bacon several times.
PS.3 - For power users
(is that an oxymoron on Win?), Windows Process Explorer can be helpful in spotting problems: http://technet.microsoft.com/en-us/s...rnals/bb896653
PS.4 - If there's any question about your DNS servers, you can hard-code this line into your hosts
file (C:\Windows\System32\drivers\etc\hosts) with a plaintext editor like 'Notepad':
(If that fixes things, then fix your DNS configs and then remove or comment out that line so that things won't break in the future if/when bikeportland.org moves to a different address.)
