(...) As for the scanners, most of them are some of the best scanners you can get, Asquared, ClamWin, Trend Mico, Panda, Sophos, and Avira are all well known and very good.
But, that's besides the point. No one scanner is perfect. Even just 3 or 4 of these scanners, not to mention all 8, running together to much better than one. And it's all automatic! If you chose to not use AVERT and use, say 4, other scanners, you'd have hope it even installs and if it does, wait for it to update, then run the scanner, uninstall and repeat 3 more times. Plus, you never no when each scanner will finish. With AVERT, once you click, "Run Scans", just walk away.
With v2.1, which I just released, I added support for scanners that are installed on your machine. At the moment, only AVG is available, but more are coming. The main point for AVERT, is to be portable, so I'm limited to what scanners I can use because of the portability factor.
And finally, about the internet issue part, I understand his concern completely. But, there are two things about that. First, AVERT has built in tools, and more are coming, that help resolve internet issues. So if malware has blocked your internet, AVERT could possibly fix it automatically. But, I do understand the need to be able to download the signature files independently so that they can be added to a flash drive and then ported over to the infected machine and I'm working on that.
