Thanks for the info I'll tell him to try the Avast or AVG, the only problem is his PC keeps freezing on him, so he may have a problem downloading. I still can't understand why he has these problems after a full system restore.
I will tell him to disable messenger,that's a pain anyway.
a restore wont nescaserily rid you of the virus as it may well be in the restore point best option is to turn off sys restore then run a full scan if you have norton set the cd to 1st bootable in the bios you should be able to boot and scan straight from the disk ( well you used to be able to still worth a try)
If,after a reinstall,he connects to the internet before he's installed his AV and firewall he could well get infected again.What i would do if he can't clean the virus is to format and reinstall again with the modem unplugged,then install his AV and firewall,if he doesn't have the discs for them he needs to d/load the setup files and burn them to CD beforehand.Once they're installed connect and update them,then do the windows updates.After that he can put his programs back.
