Which is why I don't run anti-virus software. Really... none.
you are an optimist 
And lucky too ...
From 1999 to 2006 I ran a single installation of Win2000 on my programming machine. It just worked.
From 2006 to 2011 I ran two installations of XP. The first one I mangled in a week. The scond lasted nicely.
From 2011 to Present I've run a single installation of Win7x64 and since I shut down all the background crap it just works.
Mostly I just get things stable and leave them alone... No Background defrags, no Automatic Updates, no Background Intelligent Transfers, no AV software and even the Windows firewall is shut down.
The current uptime on family server is in Months ... would have been years except for a HD failure.
The HTPC (XP / ATOM) has been on for nearly 2 years.
My smarter half's home office system has been running for several months.
My programming machine is shut down each night and restarted each morning.
It's like my father told me when I signed up for electronics courses... "Remember son, if it ain't broke, don't fix it!" ... he was joking, of course... but he was also right.
The guys with all the AV and software firewalls, toolbars and fancy gadgets on their desktops pay me some pretty good money to get their systems straightened out... So I don't mind.
