Looks like it belongs to a program that creates a virtual drive on the system, like Alcohol 120%... seems OK
It causes a BSOD
Atapi.sys 5.1.2600.1135
Von Windows benötigtesystemdatei ohne die das system abstürzt
Had a series of BSOD (Blue Screen of Death) starring atapi.sys on a PC running XP.
  Signed: Ninja(who? Hint: not Shane)  
Is part of a message when I get BSoD, error code 0x0000007A.
Simple Fix! This error message = defective RAM. Replace RAM and your laptop will spark right up.
normally a modem file
Can be associated with the Rootkit Pakes.U remove Hard disk and scan on another pc to verify
I had a virus scan identify that this was infected with a trojan and that it was an important system file. My virus scann and removal software used to remove MSA.exe also killed this file. When I rebooted, I got a virtual loop......without the file the system won't boot. BSOD occurs
04-Nov-2009 This file is highly susceptible and could become a venom for spyware and attackers at systems grass root level. I found it corrupted and the official name given is Rootkit-Pakes.U. When corrupted, it redirects HTTP traffic at system root level from ‘any’ browser to spam websites seeking traffic attention and redirects search results to websites like http://z7432632.cn

This was reported on my system by Comodo as a Trojan, removed it and caused BSOD on restart, fixed by replacing with an older version of file
VIPRE calls it a trojan
Possible file for rootkit infections. Seek professional help.
This is a windows file but can be infected by a Win32 Virus Olmarik.RF
Without it windows cannot access the IDE hard drive. So it is usefull ... Corrupted by virus, pay attention not to let you antivirus remove it as it will cause a BSOD (horrible blue screen)

Atapi.sys has recently been used to disguise infections (rootkit)

my symantec antvirus corporate client keeps flagging it as a back door trojan.
Sometimes it is infected with Packed.Protector.C, in that case you will have to replace it with the original file, for which you will need the Windows Recovery CD.
Probably short for ATA API or interface for ATA hard drives. Gmer listed this file as modified and Avast found that it was infected so i deleted it. Windows would not boot without it (BSOD) so i copied a clean copy over using bart-pe.
System file. Can be corrupted by a rootkit.
  John   (weitere Info's)
just cleaned from friend's computer, avast! free found it. Now I'm looking to see if I need to download and replace it with a clean copy. It may be what is causing his system to infinite-loop reboot after a nearly complete boot. In conjunction with temp internet file pdffile(1).pdf?
it is a virus....very hard to remove as well
Atapi.sys is a very common target of rootkits, it is a valid file, but can be dangerously modified by many malicious software.

search engine redirection

My Norton Classified this file as backdoor.Tidserv!inf. More can be read

rootkits like page redirect like to hide here
Valid system Driver for the ATA controller, however TDL3 rootkit attacks it, a 17 year old flaw in the Kernel of windows NT4-windows 7. you will know your infected from a Memory BSOD, or your AV claiming it is blocking traffic from 94.228.209.xxx
It's the hard drive driver (which is why it can hide itself from antivitus programs, you ask to scan it and it lies, returning valid info istead of the true infection info). (It can cause a BSOD if it's damaged, since the PC can't access the hard drive without it.)
  George S.   (weitere Info's)
it didn't cause a BSOD, chances are Daemon Tools did
ide controller driver
It's a system file that comes with your computer. HOWEVER, it can be easily infected and become a rootkit. If you by chance know that your atapi.sys is infected, run ComboFix. It will fix the rootkit. Also, an infected atapi.sys will generally redirect most of your searches to seemingly random assures and attack sites. Be careful.
It is an essential Windows system file. It is harmless unless modified by malware. You cannot just delete it.
Its a vital part of the windows O/S
Windows Driver for ATA peripherals, often times infected by a virus
Atapi,sys is mandatory to boot from your hard drive. It can be infected by malware. You can replace an infected or deleted file with a clean copy from another location on your system. Do a file search for other copies.

atapi.sys It's an important file to properly boot your Windows if you notice the file bytes is 96+ or 94kb below then it's altered try restoring it from the installation disc unzip the file from cd:\i386\ATAPI.SY_ overwriting(replace) C:\Windows\system32\drivers\atapi.sys

I'm not sure what it does, but it's making my anti-virus prgram go bonkers. Plus, if you delete it, it just comes back. pretty sure that's indicative of malware
The atapi.sys is a rootkit that modifies your search engienes. Adverts always come up when I search in Google. I don't know how to remove it or access it because the file is needed by windows and access to view the file is denied.
Windows critical file. ATA/IDE controller. Can be infected with rootkits.

Atapi.sys is shown as specious modification when it is infected
gives me a blue screen once a day
This file is how all of your drives that are atapi (Advanced Technology Attachment with Packet Interface) compatible function. Almost all CD drives and Hard Drives use this, therefore this is a critical system file as without it your computer more than likely will not boot. In windows vista and windows 7 you cannot stop this file using the task manager and therefore reaching this file at all in those two operating systems is not possible without some type of mod (such as an application) is not possible. with xp or earlier this program could be stopped simply by using the task manager. plenty out there just search for ATAPI and u will find tons of info.
We will see! Making it read only did get rid of redirect problem. Be advised it is an important file--back it up. We are only changing file attributes to restrict use, not deleting the file.

can be infected by Backdoor.tidserv!inf

Norton Internet Security zeigt atapi.sys als (Backdoor.Tidserv!inf) an und sagt Hohes Risiko
Microsoft patch KB977165 or MS10-015 (Feb'10) originally caused BSOD if this file was infected by the Allureon rootkit. The patch was later released (Mar'10) with detection logic so it wouldn't cause the BSOD but instead just fail to install on infected machines. If you experience a BSOD caused by ATAPI.SYS, go to the (further information) link and follow the steps to recover. This is an important Windows file.

It can be a TDSS pragama rootkit
After scan with ESET NOD32 Antivirus everything is OK. Sophos AntiRootkit reported "Removable: Yes (but clean up not recommended for this file)"

atapi.sys is also known as the Google Redirect Virus
It is reportedly an IDE Miniport driver. It can be attacked by viruses, such as the one I'm currently dealing with: Alureon.H (rootkit:Alureon- atapi). The symptoms encountered were Google results getting redirected to random spam web sites in Firefox (I tried to reporduce it in IE, but it didn't seem to affect that browser, but I've read other reports of this virus affecting all browsers). The infection is not detected by AVG free, which let it onto my system. Microsoft Security Essentials detects it on Windows 7 and seems to disinfect it, but I'm not sure if it really has succeeded.
used for optical drives, ie. cd, dvd, etc

It's the driver for IDE hard drives--can't do without it.
it is sometimes infected with google redirect virus
It is a legit file that can be infected with viruses.
This is a legit driver file (as stated by some other users) which can _get_ infected, but it is not always infected, and all XP systems will have it. Keep your virus checker up to date, and it will identify if this file gets infected (infection can mean just one additional byte added to it).

I had a virus once that replaced atapi.sys. The replacement included some evil redirections. It was fixed by hitman pro.

Was Sie bei atapi Problemen tun können

Ein aufgeräumter Computer ist die beste Voraussetzung, um atapi Probleme zu vermeiden. Hierzu sollten Sie einen Malware-Scan durchführen, Ihre Festplatte aufräumen (mit 1cleanmgr und 2sfc /scannow), nicht mehr benötigte 3Programme deinstallieren, Autostart Programme überprüfen (mittels 4msconfig) und 5Windows Updates automatisch installieren. Denken Sie immer daran ein Backup oder zumindest einen Wiederherstellungspunkt zu erstellen.

Bei einem konkreten Problem überlegen Sie bitte, was Sie als letztes getan bzw. installiert haben, bevor das Problem das erste Mal auftrat. Nutzen Sie den Befehl 6resmon, um diejenigen Prozesse zu ermitteln, die Ihr Problem verursachen. Selbst bei schwerwiegenden Problemen sollten Sie anstatt einer Windows-Neuinstallation lieber eine Reparaturinstallation oder ab Windows 8 den Befehl 7DISM.exe /Online /Cleanup-image /Restorehealth ausführen. Damit wird das Betriebssystem ohne Datenverlust repariert.

Zur weiteren Analyse haben sich folgende Programme als nützlich herausgestellt: Der ASecurity Task Manager untersucht den aktiven atapi Prozess auf Ihrem Computer und zeigt anschaulich was der Prozess macht. Das bekannte Tool BMalwarebytes Anti-Malware sagt Ihnen, ob die Datei atapi.sys auf Ihrem PC lästige Werbung einblendet und so Ihren PC ausbremst. Solche unerwünschten Adware Programme werden oft von einer Antivirus Software nicht als Virus eingestuft und deshalb nicht erkannt.
