Gstartup is Spyware (Gator)

Go to Start > Run, type msconfig, and look for lines containing the following entries on the Startup tab:

Gstartup, GMT, CMEsys, and Trickler.

Uncheck them, click OK, close Msconfig, and reboot.

End of error!

Now do this:

Download and install Ad-Aware . This is a program which scans your system for spyware/foistware.

After installing AAW, and before running the program, also download the Refupdate Utility.
This utility searches for, downloads and automatically installs the latest AAW reffile (the spyware definitions, so to speak).

Run the refupdate.exe installation file, and once installed, go to Start Menu>Programs, find the Lavasoft Refupdate entry and run it.
Click connect; it will open a connection to the internet to check and update the current signature file.

When that's completed open Ad-aware, look at the bottom left corner, it should now say "Signature file in use: "038-16.08.2002".

Then have your drives and registry scanned for spyware, check all found files and reg keys, hit 'backup', then click continue, and have them all removed.

Reboot.

Good luck,
