Infected?

I'm wondering if I got a virus. I got the death blue screen once, but only once. Things boot fine now. Anyway, later, when I try to run various applications, I get errors for some of them, like this:

"The application was unable to start correctly (0x0000005). Click OK to close the application."

Trying to search from the Start menu, it works until I click, "see more."
I get this error:
"windows cannot find "searchquery=picture". Make sure you typed the name correctly, and then try again."

My IExplorer icon also gave an error, but when I found the IE.exe and re-did a shortcut, it did work.

Any ideas?

]Thanks.

Btw, I have Kaspersky 2012.
　

Hello, jimlau.

I think in your problem that is one Virus. You can try MBAM you can use Kaspersky Rescure CD to burn one small bootable program who can scan computer before Windows start. I recommend to burn it from your friend or other computer without virus.
That is best way for you.

Try running a couple of free on-demand scanners to see if Kaspersky missed something. Folks recommend Malwarebytes and Hitman Pro. If the scans come back clean I'd next check for damaged or corrupt system files.

Run a System File Checker scan from an elevated command prompt (option two.) If any problems are noted run the scan 3 times rebotting in between each scan.

SFC /SCANNOW Command - System File Checker

EDIT: I see Maguscreed beat me to it! :)

thanks.

does unplugging your computer instead of using the shutdown option do anything bad? my computer unplugged a few times, tho i guess it's harmless?

i ran verification, and it says resource protection found integrity violations. details are included in the CBS.Log vindir\Logs\CBS\CBS.log.
should i run the repair version of SFC scan?

i think all is well now. when i ran the scan, it did not say it fixed anything. it just went to the prompt again.

i guess it fixed something without displaying what? btw, i tried to open the log, but it said i had no permission.

anyway, the programs that wouldn't work now do.

so could the shutting down the computer by unpluging have been the culprit?

thanks!
