 notice that your tablet is running a little bit slowly. If you've noticed that it's running slowly, one of the first things you want to look for is this green little V, or blue little V, in your system tray in the bottom right here. This is the school district's antivirus software. It's called Viper. And if it's green, it's running a scan. Right now, my Viper is running a scan. And I find as soon as it's scanning, everything runs slow. Everything takes longer to open. It's frustrating. So to get around that, right-click on the letter V, choose scan, and abort the scan. Now, after school, I'll right-click. Oh, then the letter V turns blue, then you know what's inactive. It's still running antivirus in the background, but it's not doing a scan. After school today, I'll choose right-click, scan, and I'll do a quick scan. A quick scan takes about two hours, so it's not as quick as you think. And you know what? Once in a while, on a weekend, I'll do a deep scan. You can also open Viper. If you open Viper, you can configure when you want the scans to run. So if you have a prep block before lunch, for example, or after lunch, you could configure your computer to do it scan during that block, then it's a little less frustrating. But I find when I'm teaching, if there's a scan going on, it interferes so much with the running of the computer, I abort the scan, and I run the scan later.
