The Problem With Cleaning Up Malware From Within WindowsRELATED:Standard antivirus software runs within Windows., the antivirus software will have to do battle with the malware. Antivirus software will try to stop the malware and remove it, while the malware will attempt to defend itself and shut down the antivirus. For really nasty malware, your antivirus software may not be able to fully remove it from within Windows.Rootkits, that hides itself, can be even trickier.
A rootkit could load at boot time before other Windows components and prevent Windows from seeing it, hide its processes from the task manager, and even trick antivirus applications into believing that the rootkit isn’t running.The problem here is that the malware and antivirus are both running on the computer at the same time. The antivirus is attempting to fight the malware on its home turf — the malware can put up a fight.
Why You Should Use an Antivirus Boot DiscAntivirus boot discs deal with this by approaching the malware from outside Windows. Boot your computer from a CD or USB drive containing the antivirus and it loads a specialized operating system from the disc. Even if your Windows installation is completely infected with malware, the special operating system won’t have any malware running within it.This means the antivirus program can work on the Windows installation from outside.
The malware won’t be running while the antivirus tries to remove it, so the antivirus can methodically locate and remove the harmful software without it interfering.Any rootkits won’t be able to set up the tricks they use at Windows boot time to hide themselves from the rest of the operating system. The antivirus will be able to see the rootkits and remove them.These tools are often referred to as “rescue disks.” They’re meant to be used when you need to rescue a hopelessly infected system.Bootable Antivirus OptionsAs with any type of antivirus software, you have quite a few options. Many antivirus companies offer bootable antivirus systems based on their antivirus software. These tools are generally free, even when they’re offered by companies that specialized in paid antivirus solutions. Here are a few good options:. – We like avast!
For offering a capable free antivirus with good detection rates in independent tests. Now offers the ability to create an antivirus boot disc or USB drive. Just navigate to the Tools - Rescue Disk option in the avast! Desktop application to create bootable media. – BitDefender always seems to receive good scores in independent tests, and the BitDefender Rescue CD offers the same antivirus engine in the form of a bootable disc. – Kaspersky also receives good scores in independent tests and offers its own antivirus boot disc.These are just a handful of options.
If you prefer another antivirus for some reason — Comodo, Norton, Avira, ESET, or almost any other antivirus product — you’ll probably find that it offers its own system rescue disk.How to Use an Antivirus Boot DiscUsing an antivirus boot disc or USB drive is actually pretty simple. You’ll just need to find the antivirus boot disc you want to use and burn it to disc or install it on a USB drive. You can do this part on any computer, so you can create antivirus boot media on a clean computer and then take it to an infected computer.RELATED:Insert the boot media into the infected computer and then reboot. The computer should boot from the removable media and load the secure antivirus environment.
(If it doesn’t, you may need to or UEFI firmware.) You can then follow the instructions on your screen to scan your Windows system for malware and remove it. No malware will be running in the background while you do this.Antivirus boot discs are useful because they allow you to detect and clean malware infections from outside an infected operating system. If the operating system is severely infected, it may not be possible to remove — or even detect — all the malware from within it.Image Credit.
Julea, I don't use Avast but I found the following at another site and it may be of help to you. All you'd have to do is reverse the procedure to eliminate the boot scan.' I use Avast for antivirus and you can schedule a 'boot time scan' by right clicking the icon, choosing 'Start Avast Antivirus', and let it do its memory scan. Once it brings you to the interface, click the little up arrow on the left hand side and choose 'schedule a boot time scan'.'
'Reboot your PC, and Avast will do an offline scan for you that should catch everything. Make sure your definitions are up to do before scheduling. Depending on the speed of your computer and the number of files you have, this scan will take some time. Expect to be without the computer for a while'.Tufenuf. Well, this morning when I booted it, it did not do the scan. Since I'm new to Avast, I need to find a forum where I can read what others say or do, and where I can ask questions.

It's quite different than AVG which I used for years!Wonder if I need to leave ALL default settings or change any specific. I can't tell if it's scanning incoming mail, even though I found a setting that is checked for that. Everynow and then I see the little globe in navigation area whirl around, but don't know what it's really doing. What is it doing (LOL)?I did find someplace where it scanned my incoming cnet email - don't understand what I really saw because it had the number 3, but only had the subject of 1 of them - there were only 2 (not 3) emails from cnet - so that confused me. Too, that was for our main account and I wonder if it scann my other 80 emails from my 2 gmail accounts I have set up in Outlook Express.It's just a matter of getting used to something new I know, but I need to feel more comfortable with what it's really doing.Thanks for your response.Julea. At Avast?If so, it was replied to 47min after you posted.
(Some of these helpers must stay up all night!)I know what it's like trying to get your head around a new installed program. I found my third AV (AVG, actually) difficult to work out at first. Basically, it works 'out of the box', nothing needs to be changed (except for the database to be updated) as soon as it's installed. Anything opened via gmail, by that I mean an attachment, is scanned on opening. It behaves like any download from a web page in that regard.Once you've installed an AV (or AS, or similar) it's a good idea to practice navigating the menus, without changing anything, just to see what does what. The help file is also good.FWIW I've always found the Avast forum one of the best. Of AVG suits you.
Some have described it as 'bloated', containing a linkscanner (sort of like siteadvisor) and antispyware, totalling a lot more memory use than the 7.5 AV. However, most reasonably modern computers should cope with that without even raising the pulse.Grisoft used to provide a free AV, and AS, and Antirootkit available for separate download. Those days are gone. I reckon they're heading the same way as Symantec, when it took over Norton.That said, you have to be happy and confident with what you use. That's the bottom line.
Both AV's perform very respectably in independent (non-sponsored) tests/reviews.Avast have an uninstall tool available, should you get weird conflictions, for info. I've never had any problems with their standard uninstaller, though. To gain confidence in a different application.I've found the Avast forum particularly helpful in that regard. More tips than a needle factory.Once you learn how to navigate the menus, and the different ways to access the (which seems a bit confusing at first) you'll probably grow to like it.Re the plugin. If it is in fact a false positive, might pay to report it in the Avast forum.(email to 'virus@avast.com', zip, password protect it, include the name of the password in the message, mention the FP thing.)Chances are fair that someone else already had the problem.
You could, if in doubt, upload it to Virustotal for independent online scans (about 3 min.)If it is definitely a FP, you can set Avast to exclude it from scanning:Standard Shield(left click the tray icon then select), Customize, Advanced, Add andProgram Settings(right click the tray icon), Exclusions.

How To Do A Boot Scan In Avast
As surprising and ironic as it may seem though, the most common cause of DBX corruption is not a virus, but rather anti-virus programs that are configured to scan incoming or outgoing e-mail. Even the most well-known anti-virus programs have exhibited this problem from time to time. To lessen the risk of such corruption you should disable the e-mail scanning module in your anti-virus program. This is usually easy to do by looking at the user-configurable options in the anti-virus program.
Mcafee Boot Scan
It is not at all necessary to scan e-mail for viruses to protect your computer.Now before you dismiss me as mad, let me explain why e-mail scanning is unnecessary. Almost every anti-virus program for Windows installs by default a system scan that runs in the background every time Windows starts. This scan is necessary to protect your computer. If you receive a virus in an e-mail attachment, the virus cannot do anything at all until you actually open the attachment. At that time Outlook Express extracts the attachment from.'
