AUTOEXEC erased

By tornado30 ·
When I am RESTART the computer I found that the AUTOEXEC.NT is erased from C:\WINDOWS\SYSTEM32 everytime, then I put it back again and when I restart the computer again it is erased. If someone can give me some hints on how to solve this matter I will appreciate it. Thanks.

Sounds like a virus. Boot, scan, clean, run.

I do not have their websites on hand but check for spyware using FREE Spybot Search and Destroy 1.3 and Lavasoft's Ad-aware SE. Yes, use both.
If you have a virus program and it finds nothing, do some online scans at www.symantec.com and whatever the site is for Microtrend's Housecall. I have another one but I have to find it.
Hopefully you can get cleaned up with these. Nothing beats more than 1 scan.
I will find those exact sites and post back shortly. I am just not at my desk at the moment. I have 1 or 2 online virus scan sites that also repair and not just scan. I just got to get them for you.

If the file keeps disappearing then you either have a virus or malware on your computer. You can copy the autoexec.nt file from the c:\winnt\repair (or c:\windows\repair) back to the system32 directory and then make it readonly. This will prevent it from being deleted but you will still need to find the cause. Here are some links to the utilities you will need (they are freeware):

AdAware: http://www.lavasoftusa.com/software/adaware/

Spybot: http://www.safer-networking.org/en/download/index.html

If you do not have an anti-virus program get a free one. I like Grisoft's AVG:

http://free.grisoft.com/freeweb.php/doc/1/

With each of these, download them, install them and update them before you run them. This should find the malicious virus or app that is deleting the autoexec.nt file.

Cheers.

Turn off system restore if it is used in your os.

Download, update, and run the following.

This program is useful in that it shows what is currently loading on startup. You must know what is good and what is bad. Once you check it and fix it is gone. So be sure. Items you are not sure of do a Google search for them.
