Some people consider 'The Reaper' the first antivirus software ever written – it may be the case, but it is important to note that the Reaper was actually a virus itself specifically designed to remove the Creeper virus. The Creeper virus was eventually deleted by a program created by Ray Tomlinson and known as ' The Reaper'. This computer virus infected Digital Equipment Corporation's ( DEC) PDP-10 mainframe computers running the TENEX operating system.

Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity (privacy), online banking attacks, social engineering techniques, advanced persistent threat (APT), and botnet DDoS attacks. In particular, modern antivirus software can protect users from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraud tools, adware, and spyware. However, with the proliferation of other malware, antivirus software started to protect from other computer threats.

Here is the output from sudo apt-get update: sudo apt-get update Updates from the Update Manager worked fine and I could download some things (mutter) from the Software Center without incident, which makes me think I can connect to some subset of the Ubuntu servers (however, several other Ubuntu servers-like extras-and some canonical servers are listed as 'unable to connect').

as well as the 'main server' (wherever that is) and they all yield the same result: I can't connect to any software sources.Īdditionally, I'm fairly certain the problem stems from the upgrade from 11.10->12.04 I performed this morning, as updates worked immediately before. Additionally, I've tried several different servers in Europe and the U.S. I realize there are dozens of 'apt-get update: failure to fetch' questions (I read through all I could find), but my present circumstance is unique to 12.04 and it affects all sources not just launchpad.
