i have recently begun having many popups from sites wanting me to install WIN ANTIVIRUS PRO.
i have also had many dialog boxes by my antivirus software (Anti VIR) about many trojan horses and such like
i have managed to clear many of them using the usual tools (spbot, spywareblaster, ad-aware) but these are not able to remove on file from the windows>system 32 folder
this file is: jkhfc.dll and is about 500kb, none of the software above recognises it, i have started using spyware-guard, and this recognises it as a BHO that has latched on to Internet Explorer. i have attempted many times to delete this file manually and using various programs (win-patrol and spyware-guard and trend micro housecall) but all of these attempts have failed as the following message is displayed:
Access denied as file is in use, please make sure the disk is not write protected and start again. but as i have found this file is in use most of the time, it has also messed around with my desktop (please see attatchement - look at the icons!!)
can anyone help??
