Problem with a possible virus

A friend of mine has an account with btopenworld.com. In the last six months his account has been taken over at least four times by some sort of bug-virus, virus which sends a message to all his contacts saying that he is on holiday in Jakarta, or Zimbabwe, or whatever, and that he has been robbed of all his money, and asking the recipient to help him by sending money; he also loses all his contacts, and bt has to recover them for him (every time..!). He then changes his password (every time...!).
Although he has his antivirus program up to date (I don't know which one he uses, but probably one that bt has recommended), is it possible that some malware is still in his hard drive, and that it is re-activated after a period of time? I don't know much about these things, but it seems so strange that it is happening with such regularity to the same person.
He uses a PC, with Windows 7, I think. But I could ask for more details from him if necessary (I am seeing him this week).
Any ideas?
Many thanks

Re: Problem with a possible virus

Two things spring to mind, one is that some virus software does stay resident on the pc, such as the xp2000 virus which was even able to continually change its file name. The only real way to be sure to be rid of such a virus is to re format. but the biggest reason for concern is the provider BT. They have had a major problem recently with their Yahoo email accounts and if your friend is on this package then the spike that they had is the probable cause. BT have a poor reputation in this area. 

There is also another option that could be causing it and that is as the virus is spread through email, he could be getting the thing back through someone he has infected. Forget virus software because most of it will only detect certain types of virus (no matter what the developers say) Even Norton couldn't prevent xp 2000 infecting many machines. 

Re format, change provider. frown

Re: Problem with a possible virus

A difficult one to diagnose. If your friend is computer literate I'd suggest either the AVG, Kaspersky, Comodo or Microsoft 'Boot" disks, all available free as a download but you will need to burn to a disk or USB stick. The first 3 will boot the machine into Linux (ie not a Windows environment) and run a boot sector and virus scan, the Windows version does it in 'safe mode'.  When your choice of those has been run, then use Malwarebytes (free) and SpyBot (free), finally run CCleaner (free). Failing that, best option is a clean install of Windows.
