Virus Removal

What kind of virus is it?? The first thing you can do is download or purchase an anti-viral software. The top tow recommended anti virus programs are Mcafee and Norton. They can get pricey, If you find that money is an issue there are free, and consequently less secure types of protection, available from various sites on the web. One of the top recommended free programs is AVG anti-virus available from download.com . Most current virus scanners and removers, purchased or free, can scan your hard drive. If viruses are found then most scanners quarantine the virus, keeping it in a special place until you decide what to do with it. (Delete the file or repair it, which then the program attempts to delete the virus from within the file without deleting it. If the virus you happen to have is real disastrous, meaning it infects hundreds or thousands of files, keeps popping up after you've quarantined it x amount of times, or it keeps deleting key files, then your last resort is to reformat the entire hard drive including any second hard drives or partitions. In most cases reformatting gets rid of everything on the drive which can save the computer. Although in most cases when reformatting has to be done any files you want have to be backed up, although there can be cases your drive may be too infected and it can be too risky to save any files. However, if viruses invade the boot sector of the drive and infect it, then the simple task of instructing to boot from the cd-drive first may be impossible since the BIOS may get screwed up as well.
