In 1982, as a high school student at Mt. Lebanon High School, Skrenta wrote the Elk Cloner virus that infected Apple II machines. It is widely believed to be one of the first large-scale self-spreading personal computer viruses ever created.
Skrenta graduated from Northwestern University. Between 1989 and 1991 he worked at Commodore Business Machines with Amiga Unix. Between 1991 and 1995 he worked at Unix System Labs and from 1996 to 1998 with IP-level encryption at Sun Microsystems. He later left Sun and became one of the founders of DMOZ. He stayed onboard after the Netscape acquisition, and continued to work on the directory as well as Netscape Search, AOL Music and AOL Shopping. After his stint at AOL he went on to cofound Topix LLC, a Web 2.0 company in the news aggregation & forums market. In 2005, he and his fellow cofounders sold a 75% share of Topix to a newspaper consortium made up of Tribune, Gannett, and Knight Ridder. Currently, he heads the startup company Blekko Inc, an internet search engine, which began public beta testing on November 1, 2010 and recently gained Marc Andreessen as an investor.
He was involved in the development of VMS Monster an old MUD for VMS. VMS Monster was part of the inspiration for TinyMUD.
