Remove virus manually which creates autorun.inf and does not opens drive on double click

When a drive is double clicked it checks for autorun.inf file which is executed for autorun. Many viruses create a file autorun.inf in each drive and try to execute their own codes on double click which prevents your drive to open on double click.

Here a tip to remove this error.

Goto your windows system32 directory generally it resides in

C:\WINDOWS\System32>

but the path may differ as you may opt for other name for your windows directory or drive.

now check following command:

.....\system32>dir/ah

It will show all hidden files in the system32 there will be three virus files namely

1. amvo.ex
2. amvo0.dll
3. amvo1.dll

delete all these files using following command.

del amvo.exe/f/ah

del amvo0.dll/f/ah

del amvo1.dll/f/ah

Two files will be deleted on of the dll file may not be deleted as it may be started now. When you will restart your system this file will be deleted automatically if antivirus is installed otherwise again apply same command and delete it.

Thanks.

SELECT TOP 1 column FROM table
ORDER BY NEWID() 

Select a random row with IBM DB2

SELECT column, RAND() as IDX

( SELECT column FROM table
ORDER BY dbms_random.value )
WHERE rownum = 1

if sts = 0 then
begin
if ( SR.Name <> '.' ) and ( SR.Name <> '..' ) then
begin
//Put User Feedback here if desired
Application.ProcessMessages;
if pos('.', SR.Name) = 0 then
begin
//subfolder put your code for subfolder
scanFolder(src + SR.Name);
end
else
//file put your code for file
end;
while FindNext( SR ) = 0 do
begin
if ( SR.Name <> '.' ) and ( SR.Name <> '..' ) then
begin
//Put User Feedback here if desired
Application.ProcessMessages;
if Pos('.', SR.Name) = 0 then
begin
//subfolder put your code for subfolder
scanFolder(src + SR.Name);
end
