which product do u use? avast internet security, antivirus or free?

R1ftgate have you tried a repair of the program? do this though add remove programs, click on avast then scroll down to repair and see if that will solve the problem for you before any further step's are taken. It will also help us if you could supply some imformation about your system. Have you fully cleaned out all previous av products.

i tried to repair it did not work i am running windows xp sp3 if that helps

[R1ftgate]

i am using avast! free antivirus

[SafeSurf]

Was this an upgrade or a clean install?
Had you just received a virus definition prior to this happening?  If not, what were you doing prior to the problem?

[Tarq57]

What antivirus were you using prior to Avast? This could be the problem, if for example, there is (or was) a trial pre-loaded AV already installed, or you had previously used another AV.

Any other security software installed?

Did you reboot after installing Avast?

Does the computer work ok, or are there other issues?

[R1ftgate]

my computer has been ofline for about two months because of a loose componant it was working fine prior to this its only now that this has started

[SafeSurf]

Let's start from the beginning.  Is your machine working fine now (we're not talking Avast)...just the machine?

[R1ftgate]

i was using symantec endpoint protection but got a big trojan and ended up with avast i also use spybot S&D but not to often

[R1ftgate]

apart from avast yes

[SafeSurf]

How did you remove Symantec?

Do you use Teatimer?

[R1ftgate]

i dont know my it guy did it

[SafeSurf]

To be sure Symantec is uninstalled properly, please do the following:

Download and run the Norton removal tool from here to clear them  http://service1.symantec.com/support/tsgeninfo.nsf/docid/2005033108162039

Reboot after you uninstall.

[SafeSurf]

Do it again to make sure.

Also, people have had conflicts with Teatime in Spybot S&D.  This software is outdated and is now replaced with MBAM (Malwarebytes’ Anti-Malware) http://www.malwarebytes.org/.  You may want to uninstall Spybot as well per the vendor's instructions.
