Windows Explorer becomes very slow after unzipping a file using WinZip, 7-Zip, unzip32, QuickZip... I can use any program and it works at normal speed, the compressor program, (WinZip, 7-zip, etc) also works, but after decompress a file Windows Explorer becomes slow, and more slow, (it takes 10 seconds to open a folder!), and finaliy crash and I have to restart the computer. I check for viruses with Avast! Antivirus, but it doesn´t find anything. Can some body say me what is the problem?

Hi,
Does this happen only on a certain file that your trying to unzip? If so try running a virus check on the file itself before unzipping. Also I would run a good spyware program like SpyBot or AdAware. Or if the file itself maybe corrupted. Also this maybe a longshot but try uninstalling all the unzip programs and reinstalling one. Maybe a registry conflict between them.

Checkout the following site. It may be the answer to your problem. It fixed a similar problem on my systems.

The suggestion in #2 worked for me when I tried it some time back. In fact I've now got this as an option worked by .bat & .reg files (yes, the registry changes too).

Be aware though that this change came about as part of IE6 cumulative update 890923 which involves security issues. If you go to Windows Update afterwards it will re-offer this update, so there would appear to be a security risk.

What about adware and spyware? Have you checked for these?

You can avoid many of these Windows problems with Linux. Linspire eases the transition for new users

Yes, I think it would be worth checking out more basic things for starters (as per #4). Also look after general housekeeping, clearing temporary internet files, defrag and so forth.

I've been back through my records regarding the fix given on the website in #2 and have done a few new experiments. Remember that the website fix was only tried at "that time". Since then there have been several Cumulative IE and other updates (890923 is now history). The two files are basic to Windows and anything could happen if old files are put back onto a system when later updates have not taken them into account.

Although I do believe there is a bug, it is not one that usually causes much hassle, maybe the odd freeze when clearing a stack of files from the bin etc. There is also the security issue I mentioned. I've been running without that website fix for some time and have not experienced much trouble, or the symptoms originally posted.

Hello. I tried all your suggestions, but I cannot fix the problem, I think it may be a Windows bug because I reinstalled Windows, and unzipped one file using WinZip, I am sure such file, and WinZip file are clear of viruses, but I have the same problem.
Thank you very much for your help.

Well, I'm a bit lost too.

The only thing I wonder is if all these zip programs might be causing some compatibility problem. I assume you need them all for different file types or something.

Make sure they are NOT all set to handle the "same" file types. Most zip programs have somewhere you can choose which file types they handle - there should be no overlaps.

If you can manage with less zip programs then uninstall them and just re-install the minimum number of programs you really need.

Other than reformatting that's about all I can suggest.
