Just being on the internet is enough to infect you with malware, viruses, trojans, etc...

I don't know your browsing habits, but it's a good bet that you've got something unwanted on your netbook. That's the only thing that can slow down a computer in a matter of days...

Also, having too many programs open (or loaded during startup) can slow performance down especially if you've got a small amount of RAM.

Go to Start, Run, type in: "MSCONFIG" (no quotations), then hit the 'Startup' tab. Uncheck everything in there except for your anti-virus, sound driver, video driver, and network driver. Apply/OK, and restart.

Keep your startup list limited to just that. You don't want a bunch of unneeded crap starting up when your computer does -- hogging what little RAM you have. Netbooks aren't that fast to begin with; being that they don't come with a lot of RAM, nor a fast processor in the first place. Also, you should download and run a scan with Malwarebytes.

Try this:

Firstly, boot your computer to the Safe Mode menu screen. You do this by repeatedly pressing F8 as soon as you boot up. Once there, use the arrow keys to highlight Safe Mode with Networking. Continue to boot from there, by pressing Enter.

If that's successful, download and run TDSSKiller.exe from Kaspersky Lab. It's tiny, and takes just a minute to run. It hunts down and kills a specific family of rootkits. Here's a link:

Regardless of the results, download the free version of Malwarebytes' Anti-Malware (MBAM). Install it, get updates and run a full scan (still in Safe Mode). Here's a link:

After that, boot normally and run another full scan with MBAM. It will detect any malware that wasn’t running in Safe Mode.

You should now delete TDSSKiller.exe, as updated versions are often made available. Malwarebytes' Anti-Malware can be easily uninstalled, should you wish to do so, but it may prove to be beneficial in the future.

Hope this helps.
