Obviously you wouldn't =.= if you have made viruses or even worked with security systems you would know would not know if someone was sending you a virus.
3 years ago I was using limewire and I didn't even download anything, 63,000 intrusion attempts were made on my computer using the Ultor's Trojan Horse.
Just yesterday, 1 person used some new Trojan to try getting through my firewall, 192 times in 3 minutes.
A download I got from some server last december, before I joined Anima, I got a mad worm, it disabled my 3 firewalls, 2 anti-virus systems, task manager, etc. Those are just a few things that are examples of how you DO NOT know when you have a virus.
Back to the main topic...is there any change in the scenario you are having with the browser and RMS?
