Can you confirm that your browser isn't being hijacked by existing malware on your system? On a side note, feel free to use AdBlock if you think it's coming from the ads.
I've been loading pages in and out of the game all day today and never had to wait more than 1-2 seconds (at the worst) for a page to load, so I can't reproduce the speed problems you're claiming. Interestingly, I've used Vista for years and haven't had any problems. Granted it's less polished and optimized than Windows 7, but I find most whining about Vista to be greatly exaggerated.
As for the malware source, you can post the IP here.
I was already using Vista when everyone else was using x p. Had it fresh off the shelf and thought it stunk from the beginning. I can tell you they never improved on it since. There's still many features that just won't work on Vista, or will work on the 32-bit, but won't work on the 64-bit or vice-versa. They couldn't wait to market it & stuffed it in every new computer on the shelf before they realized it had issues. Also, I was using Windows while the rest of the world was still on MS-DOS (21 years ago) & was using a type of 'internet' in the military long before it was ever public (22 years ago). Since I have experience 'enjoying' computers for at least a quarter of a century & have had a chance to sample many different aspects of these overgrown word processors that are interconnected, I'm not as unconscious as one might think when it comes to computers or voicing my opinion about operating systems. I say Vista stinks compared to x p, or even 3.1. But this isn't point.
I forwarded the files to AVG & as for slowness & malware, whenever I catch something, it IS from YOUR site, & after its quarantined, & after I clean temp files, I can log on again & speed won't be an issue until another malware/trojan is quarantined. As far as my system being hijacked, the only time I have difficulties & malwares is when I'm on YOUR SITE. The last one that was caught came when the page http://www.airline-empires.com/index.php? opened. As I said, it's being picked up on pages that don't particularly have ads. In regard to speed, the longest I had to wait for a page to load this evening was about 2 or 3 minutes. As I've said, the site is stumbing all over itself & it wasn't like this before when I played AE7 in the spring.
HERE IS THE IP web address that was in the suspicious file: http://65.77.131.5
