I was wondering how can i run Boot-Time scan without need of running avast! GUI (in case if some virus blocks GUI startup). system May 14, 2004, 8:38pm 2 This thread might help. Technical gets very technical towards the end. RejZoR May 14, 2004, 8:57pm 3 Aha thanks,but unfortunately there is nothing about Boot-Time scan :-\ Actually this is for my tweak tool for avast! so its somehow very important to me (and also useful in case of some serious system infection). RejZor the boot time scanning must be configured at the Windows Registry.Probably you must check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager dnd the value BootExecute.You must add a reference to aswBoot.exe after the ‘autocheck autochk *’ value usually there.Take care, I did not test this way before…You will make the dirty work. If it works, will you add to your great tweak tool? ;D RejZoR May 16, 2004, 6:56am 5 Ofcorse i’ll add it! This will be solution for all infections where avast! cannot run because some virus kills it immediatelly when its detected in memory. VPS and Core update function is already implimented in my tweak tool so you can update avast! even if its not running. If i manage to add this than hehe it will be a very good day ;D RejZoR May 16, 2004, 7:16am 6 Ok i got all required resources! Now comes the fun part (scripting ). I think new version of tweak tool should be ready today with new boot-time scan function. RejZoR May 16,

It offers to launch a boot-time scan—a powerful feature. The boot-time scan runs before Windows has loaded so that rootkit techniques are prevented from working, and most malware has no chance to defend itself against removal. You do have to keep an eye on the text-only scan when launched automatically, because it will ask what action to take the first time it hits a malware-related file and again if it finds an infected file in a system folder. If you request a boot-time scan manually, you can preselect the program's actions, thereby letting it run unattended. The program's user interface looks more like a media player than like your average antivirus. You click a few big buttons to select where it should scan; choose a quick, standard or thorough scan; and click what looks like the Play button. Simple! And it's fast, too. On my clean test system, the standard scan took less than 10 minutes. The thorough scan took around 15 minutes, about the same as the spyware-only scan in SUPERAntiSpyware Professional 4.0. It's much faster than Webroot AntiVirus with AntiSpyware and Firewall or Spyware Doctor with AntiVirus 5.5.—Next: Testing the New Malware RemovalTesting the New Malware RemovalI hadn't tested avast! against my malware collection before, because previous versions promised only to remove viruses. For this inaugural test run, I started by installing the app on a number of test systems infested with malware samples, including adware, spyware, worms, Trojan horses, rootkits, and rogue antispyware products. One of my samples tried to interfere with installation of security software, but avast! installed without any trouble. I frequently see problems with system stability when a security product's installation requires a reboot. If a preinstall scan or real-time scanner deletes part but not all of a seriously entrenched malware program, the system may blue-screen on reboot or simply hang. While avast! does need to reboot to complete its installation, it caused no such problems. It did offer to run a boot-time scan during this initial reboot. To get a clearer view of the program's operation, I declined that offer.Once I launched avast! it began detecting malicious software in memory: I heard its siren and audible warning over and over again. In all but one test system it asked to run a boot-time scan. After the boot-time scan completed and Windows restarted, a couple of the systems requested another boot-time scan because they detected threats still running in memory. What the heck—I allowed it. But on one system, avast! remained locked in combat with a particular sample, never actually able to remove it or even stop it from running. After four boot-time scans I had to admit that it wasn't going to get any better.Cleaning up these infested systems took a while, but overall it was quicker and less troublesome than running Spyware Doctor through the same tests. The results were surprisingly good. Allowing full credit for removal of all executable files associated with a sample, and half credit if it detected a
