When i type a URL in address bar, it always redirects me
to an internet explorer navigation site called
Perfectnav.The URL's I use are a valid addresses and
should work.Its getting very frustrating.

Check out the following to get rid of your problem.

Get this file:

http://www.kellys-korner-xp.com/regs...oreSearch2.REG
After downloading it, right click it and choose Merge.

Download/run Cool Web Shredder from:
http://www.merijn.org/

For Info on Cool Web Search Variants:
http://www.merijn.org/cwschronicles.html

Download/install/run Ad-Aware from:
http://www.lavasoftusa.com/
This will detect any spyware on your system. When you run Ad-Aware, click on
the ref update to get the latest up-to-date ref file, run Ad-Aware and
delete everything it finds.

If you are more advanced, then download/install/run:
Spybot - Search & Destroy from :
http://security.kolla.de/index.php?l...&page=download

If you still have problems, download/run HijackThis from:
http://www.merijn.org/
Be very careful with this program though. Do not remove anything that is
referenced by it until you get advice on what to remove as it will list some
good items as well as bad ones.
See http://mjc1.com/mirror/hjt/#quick and read the quick start on how to
create a log file that can be sent to a forum that can provide assistance on
removal of unwanted problems.
Post the logs to an appropriate NG here where they specialize in
spyware/hijacker removal:
http://forums.spywareinfo.com/

At the very least you should have Ad Aware present on your machine and run
it periodically.

Hope this helps,

Martin

You have probably inadvertently downloaded and installed adware,
spyware, parasite, trojan or a browser hijacker from some web site:
