LEN, here are some programs to help fix security on your PC
I will make and assumption that you are running Windows 2000 or XP If so, follow these steps: (note: all of these programs are free to download and use )
1) Download and run Microsoft's Malicious Software Removal Tool from this site:
http://www.microsoft.com/security/malwareremove/default.mspx
It can find and remove a number of harmful programs.
2) Download and install Microsoft's Free Defender Spyware Protection program
http://www.microsoft.com/athome/security/spyware/software/default.mspx
Once it is installed, do a full scan and remove anything that it finds.
3) Turn off Windows Messenger. To do that, download and run the Shootthemessenger utility from this web page:
http://www.grc.com/stm/shootthemessenger.htm
4) Download and install the Lavasoft Adaware program from this web page:
http://www.lavasoft.de/ms/index.htm
and then run a scan with it to remove anything it finds.
5) Finally, download and install EWIDO from this page:
http://www.ewido.net/en/download/
and scan with it to remove any software it finds.
I am assuming that you an AntiVirus program installed and running. If so, make sure that its virus definitions are fully up to date by using the update feature in it.
If you don’t have any AntiVirus installed, or if your AntiVirus software has expired, and can no longer get updates, then be sure to install an AntiVirus program also. First uninstall any old AntiVirus programs by going to the Windows Control, and using the ADD OR REMOVE PROGRAMS program. Select the AntiVirus program from the list of installed software, and then click on the ADD/REMOVE button for that program to uninstall it.
A good FREE AntiVirus utility that you can download and install is the AVAST program. It can be downloaded from this web page:
http://www.avast.com/eng/avast_4_home.html
So install this program, if you don’t already have a working AntiVirus program. And then after installing, be sure to run a full system scan.
Finally, Microsoft has a lot of good information about Computer threats available to read on this web page. So if you would like to learn more about computer security threats, I highly recommend that you read the articles on this page:
http://www.microsoft.com/athome/security/computer/viruses/protectyourcomputer_viruses.mspx
In particular, check the article titled: Browser Hijacking, to learn more about this type of threat.
Some would consider doing all of the above overkill. But if you get and use all of these programs, you will have an excellent chance that you will be able to clean any malicious software of any kind from your computer.
Good luck to you in getting your computer healthy again.
