You need to post this on the other side to get help.

I'm not sure I'd want to connect a Windows 98 PC to the internet. It's no longer a supported OS so it is likely to have security issues. What kind of internet service you you have? I'll give instructions that assume some sort of broadband (DSL, cable, FIOS etc). If that's the case, you have some sort of device plugged into the line that then is connected to the PC by a network cable. You'll need to by a router. There are basically two options here. You can get something that is wired, which might be a little less money. The drawback is then you'll need to run wires to the other PC and if you ever move it, you'll need to run wires to the new location. By the time you run the wires, even if you buy the parts and do the work yourself, the cost advantage may be gone. The second option is to buy a wireless router. Since you also need to connect your existing PC, you'll want one with some wired ports on it (most have several). You'll also probably need to buy a wireless card for the windows 98 PC. When you do, make sure it has drivers for Windows 98. Windows 98 is no longer supported by MS, so it may be difficult to find cards with drivers. If the PC has USB ports, the easiest approach is to get a USB wireless card. If you don't have USB ports, you can buy a card that plugs into the motherboard. Plug the router in to the modem and plug the XP PC into it. Configure it for your internet service if necessary. Also configure it to use encryption. WPA is best, WEP is a distant second best. Connect the USB card to the 98 PC. If you don't have USB, unplug the PC, open the case and plug in the card. Install all of the drivers according to the instructions that came with it. Configure it with the same security as the router. Now you should be ready to go.

I don't see an issue with AVG on 7. I do see an issue with McAfee see link. If you like AVG and are use to it then for sure consider it. Download it to the desktop and install it. If you restored to factory settings like you said McAfee should not be active, a perfect time to uninstall it. It should uninstall using programs and features, we don't even need to worry about that yet because no McAfee files are running yet. Note The McAfee removal tool is not removing some new versions of McAfee. "Enterprise Software Detected" please contact McAfee. Lets avoid that or it's off to Revo un installer. When you get home connect Ethernet cable to the laptop. Then try going to www.google.com. Only go there just see if Google opens. Let us know if you get this far and we can give you a direct link for AVG so you may install that. Then while McAfee is not active we can uninstall it as I mentioned. If you want I can look at a hijack log for you after.

It does not seem to be a network adapter issue either, as both wireless and direct connection are problematic. The next step to see if a program typically Anti Virus is causing issue. So lets boot the computer to safe mode with Networking and see if you can connect that way, lets just concentrate using a direct connection. Restart the computer, keep tapping the F8 Key, the computer will boot to the advanced boot options menu black screen with white letter. From the list presented to you, use the arrow key to select Safe Mode With Networking once selected hit enter on the keyboard. Now try to connect to only Google.com. Let us know if you can connect that way. Do not surf the internet in this mode. Please be sure to try another browser too maybe before doing all this above in case this is a silly internet explorer issue.. Joe
