Try NOD32 Antivirus, if you think it's a virus, Is your OS on a separate partition from everything else?

Defective or dirty keyboard. Clean out thoroughly while upside down, using Dust Off, or other canned air, and a Q-Tip with 90% alcohol. If the cleaning doesn't help, try a borrowed keyboard.

uhh what do u mean by that

 

[drewboy16]

i dont think its a hardware problem becuz last month i had the same problem then i reformatted the os and the problem instantly went away then recently as soon as i started downloading movies again the problem is back so i think its a virus but somehow antivirus is"nt picking it up

 

[drewboy16]

another reason y im sure its not the keyboard is because i also tried using on screen keyboard and that does the same thing

 

[drewboy16]

please help?

did you try scanning with another AV, like NOD32? Where do you download your movies from? A lot of sites are pretty infected with viruses so you should be scanning before you open any downloaded file...

 

[drewboy16]

no treats found
probably a really strong non detection infection? i scanned with mbam, symantic, eset smart security(Nod32) and a few online scans and none is detecting viruses yet my laptop is acting very weird at times.. i was wondering 2 if it was my keyboard that was faulty but on-screen keyboard proves it since im getting the same problem with that

 

[drewboy16]

i'll try combofix and hijackthis later in a few hours cuz im leavinghome right now talk to u guys then later and thx

My cousin had a similar problem with his lap top. He ended up having to have the keyboard replaced. His would do random things when he pressed certain buttons. i.e. play music, stop music, enter weird symbols and so on. Best of luck

uhh what do u mean by that

I believe if he pressed "F" then it stopped windows media player, if it was playing. And randomly while he was typing the font would change to Wingdings. It was very weird and sounds a little bit like what you might be experiencing. Although he did not try an on screen keyboard. Have you contacted the computer manufacturer?

To scan or not to scan?

This may be an EXTREME shot in the dark. But if nothing is being picked up as a virus or malware, then what about corrupt drivers?

I know it's a crazy thought, but if the computer was infected, shouldn't something have picked it up by now?

As far as the mouse jumping around, is it an optical mouse? If so, mine jumps around on my work PC and slowly moves in any given direction from time-to-time and I am pretty confident that my system at work isn't compromised with viruses or malware.

Although, I'm curious as to what causes that myself. Hmmm....

similar problem

I have a similar problem on my Sony Vaio laptop keyboard.

Here's what happened:
1. my computer downloaded some symantec live updates
2. my computer downloaded windows updates
3. my computer lost power due to battery failure
4. I pushed power to turn it back on, but the battery was so low it blinked on for a sec and then shut off again
5. I plugged in the ac adaptor and turned on the computer
6. Now, the keys on my keyboard are malfunctioning, for example, when I hit "d" nothing happens. When I hit "backspace" it displays "35789". when I hit it again, it erases the previous nine and then does 35789 again. If I hit it again, it goes to the end of the line. Every key does nothing or something crazy and inconsistent like that.

I've tried: norton anti-virus scan, ad-aware 2009 scan. According to these scans, everything's clean. I reinstalled the driver to the keyboard, but still no luck. Also, for some reason my computer cannot complete any of the system restores I try to start.

My on-screen keyboard works fine. I'm wondering if something bad happened when the compute rebooted but lost power. I have no idea what to do next.

Did you call Sony tech support?

Typical Sony hardware error. Replace the keyboard under warranty.
