My system is messed up.... and now I think I know what's wrong, and it's scary. I've been reading about viruses that mess with firmware and the bios. Here's some background:
A long time ago, about a year, I had a problem with my Dell laptop. My system was suddenly slow after booting in to windows, using it for a while, and then returning to a live CD of linux. The slowness remained despite returning to Linux. It was like the crippling virus was stored somewhere else.
For some reason everything just slowed right down. I'm almost 100% ( as in 95% ) sure it was not a typical case of viri or malware.
When I bought a new laptop, I vowed to use Ubuntu exclusively, as I was sick of windows vulnerabilities. It ran flawlessly for about a year until for some stupid reason I decided to boot into windows. The same thing happened to my new laptop, that happened to my Dell. The system got slow in Windows, and after rebooting to Linux, the problem remained.
I'm convinced something, somehow, messed with my hardware ( again ). Is there any way to diagnose this problem? Check the Bios, and hardware settings or something? Anyway to reset everything?
Given the thing's I've read on: http://invisiblethingslab.com/
and other security sites. Hardware level problems. Like things that affect the CPU. It's scary. How do I fix this problem ( besides buying a new computer and never going into Windows )? I'd like to fix this.
Please Note: I'm using a laptop. It's and HP 6730s.
You could see if HP has a BIOS update for your HP.
Flash the BIOS, see if it fixes everything.
Normal windows users don't have dramas like that unless they're installing lots of crack software, using IE6 and downloading dodgy free porn and cracks, or borrowing CDs from people who hate them, or having lots of other dodgy PCs on their network and using old versions of Windows.
SO my point there is, if it does turn out to be a virus, find out where it came from! (and install a copy of AVG on Windows).
Edit: I'm with TC, never seen a BIOS virus ever, and the BIOS is the only thing that could store software besides hard discs. So it's probably something unrelated.
It could also be a total fluke, make sure the laptops vents are clear and not blocked with dust etc.
Well technically a BIOS virus is possible, although very rare, and would still be classed as a software virus. The easiest way to resolve that is to flash the BIOS. If it still doesn't work then it's either a virus on the hard drive or it's not a virus issue at all.
