Webroot spysweeper won't sweep

Download malwarebytes (free version) and do a full scan in safe mode ( boot up pressing F8 and choose safe mode)
You could try running safe mode and trying to scan your pc with the webroot software

Do a system restore to an earlier date.

This sounds like the program glitched. Try removing it and reinstalling. Then have it check for any updates.

Email webroot and the will give you an unistaller.The re-install with your key.

spysweeper won't sweep needs to be reinstalled

Dear Sir/madam,

Reinstall it with different drive before u delete the folder of spysweeper. If you have using pirated version mean it will become problem. so get some other programs of full version. ok

thanks
good luck

i had the same problem getting also an error message when i would log in about a valid definition file and go to program option page to update the definition file, after trying fixes from others i found one that said to reboot computer and put in safe mode, then open spy sweeper in safe mode, everything was in large print and nothing was turned on, so i rebooted the computer again and this time when the screen came up came up normally and not in safe mode and most of all there was no error message, my spy sweeper is now opened and now it is sweeping like it is suppose to do i don't know who was the person that posted the resolution but thanks it works so everyone try it.

Webroot has a main page where one of the tabs across the the top is 'Shields' Click on that tab and set all shields on except the e-mail one. That one makes a mess on Outlook Express. I also dropped back a few versions since the latest one kept yakking about a shortage of drive space when there was no problem. As to alerts the program will give an ' Alert' when it thinks that a sweep is overdue. I just click on 'sweep later' and minimize the alert.There are also some good anti spyware 'freebies such as AVG and SpyBot Search and destroy

I did the live chat support. They were very helpful. Gave me a link to redownload the spysweeper product, since mine wouldnt let me do anything. It did work and my spysweeper is working great now. http://www.webroot.com/company/support/. Went to that site. requested a download and they sent it to my email right away.

you either have a demo version which when given update would ask you to buy it.... else its definition would have got corrupted... so update it,,,,
