Which was the first Windows Virus
In 1986, the first MS-DOS PC virus was created. It was the Brain virus from Pakistan. Brain was a boot sector virus and only infected 360k floppy disks. Interestingly, even though it was the first virus, it had full-stealth capability. Stoned was the first MBR infector and was written by a student at the University of Wellington in New Zealand. Several innovative viruses appeared in 1992:
EXEBug introduced CMOS modification to prevent clean booting.Groove was the first .EXE infecting MtE virus. It also targeted many anti-virus products.Invol was the first .SYS infector. It was also slightly polymorphic.Starship was a SPM, slow infector. It also introduced a new way to infect the hard drive.V-Sign was the first polymorphic boot sector virus.WinVer 1.4 was the first Windows virus.
WinVer was Windows-specific. VLAD was probably the first one to specifically target Windows 95 systems. Read: Evolution of malware.
Which was the first AntiVirus
There are competing claims for the innovator of the first antivirus product. Possibly the first publicly documented removal of a computer virus in the wild was performed by Bernd Fix in 1987. By the end of 1990 there were a number of anti-virus products available.

One other product appeared in December of 1990. Its release foreshadowed a new direction the antivirus industry would take in 1991. The product was Norton AntiVirus!
