Kind of old, but has anyone successfully done this before? I think I've tried most of the common switches, but nothing seems to work...

/Verysilent /sp-

That didn't seem to work. I still get the "Setup will install Webroot Spy Sweeper (Subscriber's Version) to your computer. Continue setup?" message with a Yes or No selection.

Not sure if this will help you or not, but I use this for version 3.2, installing with WPI

%cdrom%\\Apps\\Spyware\\Setup.exe /DIR="%systemdrive%\\Program Files\\Spysweeper\\" /VERYSILENT /NORESTART

If all else fails autoit, or get a newer version.

Definitely get the newer version. Some of the more nasty, newer spyware and malware cannot be removed with anything less than 3.0. 2.0 does not have the ability to prevent programs from re-installing themselves at startup, whereas 3.x does.

Plus, the newer version is an Inno Setup, so it's fully silent.

I didn't know that. I assumed since the definitions of 2.6 were always updated that it'd be ok. I'll probably go pick up a copy today.

Save yourself a trip to the store - just go to the Webroot home page (http://www.webroot.com/). It has the most up-to-date version, you'll have it in about a minute, and you won't have to pay tax.

As far as the definitions...I thought that too, until looking at a friend's system that had 2.6 on it and seeing that it was infested with spyware. The program would delete it, but the stuff had edited itself into the startup routine, so that it would re-install upon reboot. Man, this stuff is getting nasty!
