Please help!

When running a complete scan WD hangs when it scans:
C:\WINDOWS\Driver Cache\i386\driver.cab\te-protu.

Anyone that knos why? Is there any risk or troublebegging in deleting this
file?
 
Are you sure it is a hang? There are about 18 megabytes in various te-protu
prefixed items in that cab file.

I would not delete it--it's part of the base OS, and I suspect you need it.

What you could do is change the option that tells Defender to scan within
archive files--that should keep it from scanning in the .CAB file, and make
for a much faster scan, too.

However, you will miss some malware. What you miss isn't going to be
active--that would have been found by the quickscan, but there can be .zip
or .exe or other archives in, say temporary internet files, containing
malware. Not dangerous unless you go open them on purpose, but probably
worth removing anyway.
 
Thanks Bill for your detailed and quick answer! Now I am a little bit more
wise.

I am not sure it hangs the laptop, but when WD scans the file I am not able
to work with my computer, at all. How long should the scan of this big file
take take approx? Half an our, one our...? (I would feel more safe if WD
could scan thru these files also:)

Brgds,

The lenght of a full scan really depends on the size of the harddrive and how
much of it is used. I have a 100 GB harddrive with about 12 GB on it and the
full scan takes about an hour. A large number of files and large files such
as cabinet files takes longer to scan.
 
Ok. Thank you both for your replies!

I will try a full scan again and be more patient.
HD is 60GB with 15% free space. Still, scanning "te_protu" takes at least 30
min. This file is packed (Winrar) in folder "driver.cab". Is that of any
significance?

Hello Rob,

A Full scan in Safe Mode take 25:08 minutes, scanning 546,479 objects

I suggest scan your hard disk for errors and fix them.

chkdsk /r /f

You can also run SFC to repair a corrupted file

Goto start and run and type (remember the space after SFC)

SFC /SCANNOW

press enter and let it scan your system, if any files are damaged or missing
they will be replaced using the files on the windows disk

Thanks again! Ive already tried CHKDSK - no problemo. I will try SFC and let
you know.

You might try setting up a custom scan that would just scan
driver.cab--maybe make a copy to a created directory, so you can scan just
that directory?

This is going to vary by cpu power and ram, so I'm not sure there's any one
answer. I know I ran full scans of a whole office full of machines last
week--from PII 350's to 3 gig machines, and none of the full scans took more
than a couple of hours--and 45 minutes or so was probably more usual--I
didn't time any of them, but some completed before I moved on to do other
work on a different machine, some didn't, but none took more than some of a
morning or afternoon.

Hi Rob,

I am glad I could help and thank you for updating the thread.

The service loading the engine in Windows Defender will automatically detect
most engine hangs and submit reports on them to Windows Error Reporting.
You may see the string "AntimalwareEngineHang" if encounter one of these,
these reports should contain the problem file, which typically makes it easy
for us to reproduce the problem.

So if you unfortunately do encounter a hang and see an error report, please
submit it.

Thanks for using Windows Defender,
Joe
