For the past 1 week till now, I found that internet is slow, nothing wrong with my PC hardware, and i had updated my norton virus definition. Is it due to Sobig.F ?
You misunderstand the problem. Blaster (worse than Sobig if I remember correctly - there were a handful of major viruses/worms in the past two weeks) doesn't slow YOUR connection to the internet, it slows the internet itself. It launched a denial of service attack on www.windowsupdate.com (see the bulletin there) from each computer it infected. It had a major impact on overall internet traffic and made patching the security flaw difficult. I personally had trouble updating my computers at work because of Blaster.Originally posted by Sourire
I do know (I work for norton virus removal) that sobig.f does not slow internet connection
There are several potential causes for slow internet, including a poor Wi-Fi signal, outdated modem or router, too many devices connected to the network, and network congestion.
You can check your internet speed by using an online speed testing tool, such as Ookla Speedtest, or by contacting your internet service provider.
To improve your Wi-Fi signal, try moving your router to a central location, minimizing interference from other electronic devices, and using a Wi-Fi extender or mesh network.
If your modem or router is outdated, you may need to upgrade to a newer model. Contact your internet service provider for recommendations or purchase a new one from an electronics store.
Other troubleshooting steps you can take include clearing your browser's cache, running a virus scan on your devices, and contacting your internet service provider for potential network issues.
