Hi! Folks, I'm really going round the bend, I have a recurring virus called "istsv.exe", my anti-virus programs tell me it is a virus that dials your number at night to porn sites abroad,, and charges to your account. I did a search and found two exe files, but I could not delete them, it said that someone or another program was using them, so I went to add and remove programs and found it there, and removed it, but when I did another search there they were again, and I got the same message and couldn't delete them, nothing seems to work deleting them at all. I've AVG, spy bouncer, spy sweeper, ad-aware,spybot, and others, they all give me awarning that they are there, anny suggestions please.

go to safe mode and try again .

Check the registry. A lot of virus programs will register themselves as a service to run at startup.

Go to this website and download stinger. (small but effecient virus, trojan, etc. removal tool)http://vil.nai.com/vil/stinger Run it. Sometimes it will find and remove this problem. Make sure you clear out the system recovery files as well. Virus and trojans will leave traces there as well.

Spybot has an excellent file shredder. Drag the file into the window and shred. MAKE SURE they are the ones you want to get rid of, cause they are not recoverable after this action. Might want to use safe mode to do this, but I have done it successfully several time in normal mode.
