I recently discovered viruses on my Dell Inspiron, on two different occasions. The first two viruses were taken care of, but my McAfee Security Scan Plus always stopped working after 75% of the work completed. Within a couple of days, I found another virus, and got rid of it. And again, the scan never completed. This time, I realized that I lost a wireless internet connection. All other computers at home are connected to the internet, and they are working as usual.
I tried all kinds of things recommended to restore my connection, with no success. I tried system restore, but all the restore points before this problem were deleted. (by viruses?)
When I first tried to fix this, my computer was connected to the network/router without internet connection. Now I don't even see neighbors' wireless networks, let alone my own. I don't know what I did wrong.
I even used my system backup disc, hoping to restore the factory setting, but the disc always stopped working and never did a single thing.
My OS is Windows 7. I appreciate any help.

Try booting the computer in Safe mode with networking by following the below steps:
Restart the computer and keep tapping the F8 key on the top row of your key board until you the see the windows advanced boot menu.
Then use the Up/Down arrow keys and select the option safe mode with networking and check whether you are able to go online.
Thank you very much for your quick response.
Earlier, I found and pressed the "internet key" (? picture of tower on it) on my keyboard, with wich I now see my router and my neighbors' again.
I rebooted in safe mode with network. Now wireless network connection has "limited Access", with no internet connection. And my network is "unidentified" (public network).
Let me know; is it possible for you to connect your internet though hard wired internet connections instead wireless?
Meanwhile you can also try this step:
Open run command and type the following:
NETSH WINSOCK RESET CATALOG
Restart your computer and check whether you can able to access your internet.
I hard-wired my router and computer, but it didn't work. The only thing that was different was the computer showed two networks, one was home, and the other was public. The computer was connected to these two networks, but still not to the Internet.
I've entered that command several times in the past, but I did it once again. Nope, it didn't work. The computer briefly showed as if it was connected to the Internet, and then went back to "no Internet access". I was not able to download e-mails nor reach a web site. I now only see home network conncected to my computer.
It appears like this issue needs some more diagnostics, I have sent you an e-mail requesting for more details on the same. Kindly have it replied so that we can help you better on this issue.
Someone taught me how to reset the computer to a factory setting. Press F8 for Dell DataSafe. It's worked beautifully.
Thank you so much for informing about the status, meanwhile please let us know if you need any help with installing McAfee back on you computer.
