Fishy68 is right look under th processes tab abd try to shut down the process that is using a an unusually large amount of resources. There may be several processes running that shouldn't be but you should verify the name of a suspicious before shutting it down. Any virus or malware program that is running must be shut down to be able to remove it manually or through the anti - virus program. Some programs cannot be shut down as the will start up again in 2 to 3 seconds. Others must have the registry key reoved first and this is risky for a normal user, many IT people are uncomfortable with the registry. There are also viruses that take over your anti - virus program. To you it will look like it is running fine, but it is the virus running it. Viruses are intelligent compared to what they used to be. This is probably the best method to beat it. Remove the registry keys that correspond with the process, boot into safe mode and check the registry key to make sure it didnt come back. Typically a virus will not start in safe mode as it only loads services that are absolutely necessary to run windows. Then do a virus scan. If the virus has taken over your anti virus you must start the PC normally then shut down the bad processes and the anti - virus application then go to trendmicro.com and do an online scan. Select heuristic scan so that filles are detected. I have dealt with many of these and they can be tough. If you wish to PM me we can arrange for me to connect to your PC through msn messger and I can remove the virus for you. In the mean time refrain from making on line purchases or checking bank accounts and things of this nature. Good luck.
