RV510 15.6 I turned it on yesterday and it came on then went off then on/off/on/off etc. I removed the AVG antivirus and installed Norton and it seemed to be ok but i just tried to turn it on and it won't come on at all. I tried it with and without the power cable but it still didn't come on

Ok, then, try this:
1. Unplug your power cord,
2. Remove Battery,
3. Press power on botton for 3 sec.
4. Now plug battery again,
5. Locate F8 key (it is a single key, at top of your keyboard)

6. Press power on boton, and as soon as screen shows manufacturer logo (or memory count), start to press F8 key repeatedly until a menu display,
7. Select "Secure mode"
8. When the system starts, clic on "Start" boton, and type "recovery"
9. At new window click on "Open System Restore"
10. At new window, cick on "next"
11. From list, select a date prior AVG uninstallation.
12. Follow wizard instructions.

System will restart several times, and if you are luky, then your system will work again. And, PLEASE, Do not install Symatec any more. Try Essentials:

I would suggest avg free edition for your anti-virus which can be found here:
http://free.avg.com/us-en/homepage

and malware bytes for an anti malware, rootkit buster which is here:

You could try Avira Antivirus or Avast. I recommend Avast. Go to http://www.avast.com/en-eu/free-antivirus-download
And here is the link for the free licence: http://www.avast.com/en-eu/registration-free-antivirus.php
You will have a licence for a year.
If you need further assistance leave a comment.

You will either have to purchase another subscription from Norton or use another anti-virus. I recommend using AVG, it is free for home users and ranks at the top with Symantec and McAfee.

Try to start your windows on safe mode.
To do it restart your computer and press F8 button before windows logon appear then you will start windows on safe mode.
After you start windows on safe mode go to control panel again and try to remove it.

remove mafee from mcafee removal toll and restart the computer

i want to downlode norton antivirus software

Norton is a real pain, and can be a bigger pain to get rid of. First, go to filehippo.com and download CCleaner, and also download AVG, but save the AVG download to the desktop. After removing Norton you will be using AVG for your antivirus. Once you have the CCleaner installed, open the tools section on the left. This is an uninstaller, it works considerably better than the add/remove programs section of Windows. Remove anything that reads Norton. This is where it may get tricky, Norton has a couple of blocking programs built in that try to keep you from using another antivirus, or removing Norton. So, the uninstall may run the first try, or you may get a message to the effect of the updater is running. If you get this message, then you will need to open Norton, go into the settings, and turn off everything. Then try the uninstall again. Once you've uninstalled all Norton related programs, run the registry cleaner. Norton likes to leave a little blocker in the registry that prevents the install of other antiviruses. Noe that this is done, you're ready to install the AVG. NOTE at one point there will be a section that will install the AVG internet toolbar, uncheck this box, you don't need it, and once it's installed you can't remove it without removing and reinstalling AVG. Some finer points about AVG is very little maintenance,it updates automatically, will scan at a time preset by you, so as to not hinder your use at the time of the scan, it protects against spyware and adware along with the antivirus, and has real time internet security without using hardly any resources. I believe you will be happy with it. If you have any more questions, feel free to ask.

Hi mollducks, first things first. If you are using any version of XP turn on windows firewall. Click the start button & open control panel. Open windows firewall & click it to on if it is not on.
Try downloading AVG antivirus software for free at this link:
http://free.avg.com/ww.download?prd=afe Than run it. Full system scan.
After you run AVG on you're system use Norton’s remove utility to uninstall any left over files from Norton.
AVG should have caught any virus.
http://service1.symantec.com/Support/tsgeninfo.nsf/docid/2005033108162039
If you bought Norton antivirus software for download, go to this Norton site & click support:
http://www.symantec.com/norton/support/index.jsp
If it was the free download, try again to download it.
Norton should do a quick scan during installation.
You might want to keep AVG. Norton should still install with AVG already installed. You can remove AVG at any time.
Lastly, once you feel there are no virus's in you're system shut down the PC. Unplug the power cord from the PC. Open the case & gently remove you're memory DIMM's. Wait 1 minute & re-install them. Make sure they are correctly connected. Double check all data & power cables are securly connected & close the PC & plug the power cord back in. (By doing this you remove any virus that may be hiding with in you're memory).

Good luck mollducks!
Feel free to ask if there is still an issue with norton after running the above sugestions.
