My Anti-virus software detected some PC Doctor files that were infected by the W32/Susema-based!Maximus virus. Said I should delete the files, so I did. Now of course I can't open PC Doctor because it says it can't find certain files. My question is do I really need this on my PC? I've never really used it and it came with my PC. If I uninstall it, will it affect anything else on my computer, or am I just better off without it? And if I remove it, is there a site which will allow me to reinstall it?
