is it possible that virus can't be deleted?

Question

what to do if it happens

Answer 1

Yes, there's every chance that the virus can't be deleted.For, example If your system is infected by a "boot-sector" virus or a "Bot-net" virus then complete removal of these variants are very difficult.Since, they create a copy of itself on almost drive or folders(restore points etc.....).And they are loaded into memory every time the system is started.
In these circumstances, a thorough format of the "disk" is needed. And once done, you would have to reinstall the operating system from scratch..........

Answer 2

You need some powerful tools to remove it. Also i would need to see a HJT log.

Please come along to http://thecomputerforums.freeforums.org/ and register then post in the introduce forum and then post in the malware and Security forum saying what problems your having and we will help. We are a new up and running site.

Please register now if you want the help, as we are changing domain name soon.

Edit: Yes you could do a clean install, but it depends exactly what you use your computer for. Do you do online backing if so, disconnect from the net and do a complete re-installation. But if you just download music and play games then cleaning your system is the better option. But you mat not have a virus, you aint explained if your having any problems (If Any). I would need to see a HJT log, to go any further on this, so please go to the site i said and register if you want help.

Yes, it's VERY possible. Today's malware is becoming so advanced that many simply cannot be removed by traditional Anti-malware tools. like some Root kits.

There is only ONE way to be sure that all malware is gone from your PC:

Back up all personal data from your PC ("Backup" means: copy to CD / DVD / external hard drive). Then, do a Windows XP "Clean Install", for further instructions, go to =>
