Computer Go Wrong when Connet with Net

Maybe you could try restoring your computer to an earlier time when you didn't encounter such problems? At times I do that when I suspect virus attack. Recently, I restored my computer to factory settings because it apparently crashed due to severe virus attack. Now, thankfully, my computer is working fine.

batter will will be a complete virus scan with a good antivirus...as it's sounds like a virus problem....I f you are getting this trouble these days only then you can go for a system restore for that you need to have a restore point created already....If all in vain...then you must go for a complete refreshment and that is format....before formatting take a back up of all the files in your PC...

I am pretty sure that this is a trojan virus, follow these steps to get rid of it : (i assume you're running Windows OS) 1. Disconnect your internet connection. 2. Go to run - Type "msconfig" (without quotes) - Go to "Startup" Tab 3. Uncheck "Startup Item" that looks suspicious and uncheck it. 4. Now look at those item location (See "Command" and "Location") 5. "Command" will tell you its folder, go to this folder and delete suspected files (usually it has "*.exe extension" with "weird or interesting name" like abcdef.exe love.exe and it has "unique and interesting icon") 6. "Location" will tell you its registry key, now open your registry by typing "regedit" on "run". Go to this location and delete the suspected entry. (but be careful not to delete the legitimate one) 7. Now restart your computer and Try to connect to internet again. 8. Is your problem solved? (Some trojan virus written in high level languange like c or c++ can't be detected by most antivirus software)

check your modem connection or uninstall the modem software and reinstall modem driver.. but before you do the reinstallation make sure you make full system scan on your computer.. virus removal, disk defragment, disk clean up, clear your cache memory and etc... Or maybe some of your applications blocking your internet connection.. try to configurate your system running msconfig and unchecked those unnecessary application on your system.... Goodluck!!..^_^

maybe your computer has infiltrated by malware. clean it, use malware detector. if it still happen, check your hardware. check it. if you nope found it, isuggest you to bring it to computer repair. hehehehee....

Your computer may be affected by a virus.Please make a boot scan.it take long time it is very useful and safe.

hi olleenz check your internet card on the motherboard or have a computer nerd friend do so as if this is bent or worn out you are not getting on the net until you instal a new card. been there and done that. we checked for virus no virus. we checked everything else but then my son checked the internet card and it was worn out, replaced it and I was back on the net.

I guess it's a virus. Try to format your computer and see if it solve the problem.

I suggest you use Malwarebytes' Anti-malware to check your system. Its free. But as you have stated, you're having problem connecting to the net. Maybe you can go to a friend with an internet connection, and download it from there. Also, run the Malwarebytes in Safe Mode, it certainly helps to run it there so that it can detect everything.
