SCP Computers - Virus Removal

If your computers have suddenly started to run slowly, keep crashing or freezing up, or browsing the internet is slow, the likelihood is you have a computer virus.

 
 

A Bit About Viruses

Computer viruses are the "common cold" of modern technology. They can spread swiftly across open networks such as the Internet, causing billions of pounds worth of damage in a short amount of time. Five years ago, the chance you'd receive a virus over a 12-month period was about 1 in 1000; today, your chances have dropped to about 1 in 10.

Viruses enter your system via e-mail, downloads, infected floppy disks, or (occasionally) hacking.

By definition, a virus must be able to self-replicate (make copies of itself) to spread.

Thousands of viruses exist, but few are found "in the wild" (roaming, unchecked, across networks) because most known viruses are laboratory-made, never released variations of common "wild" viruses.

Virus behavior can range from annoying to destructive, but even relatively benign viruses tend to be destructive due to bugs introduced by sloppy programming.

A virus is just a computer program. Like any other program, it contains instructions that tell your computer what to do. But unlike an application, a virus usually tells your computer to do something you don't want it to do, and it can usually spread itself to other files on your computer -- and other people's computers.

If you're lucky, a virus will execute only a benign "personality quirk," such as causing your computer to make seemingly random bleeps. But a virus can be very destructive; it could format your hard drive, overwrite your hard drive boot sector, or delete files and render your machine inoperable.

Malicious Code
A common misconception is that other kinds of electronic nasties, such as worms and Trojan horse applications, are viruses. They aren't. Worms, Trojan horses, and viruses are in a broader category analysts call "malicious code" or "mal ware"

A worm program replicates itself and slithers through network connections to infect any machine on the network and replicate within it, eating up storage space and slowing down the computer. But worms don't alter or delete files.

A Trojan horse doesn't replicate itself, but it is a malicious program disguised as something benign such as a screen saver. When loaded onto your machine, a Trojan horse can capture information from your system -- such as user names and passwords--or could allow a malicious hacker to remotely control your computer.




Spyware
Spyware is a piece of software that collects and sends information on users (such as browsing patterns in the more benign case or credit card numbers in more serious ones) . They usually work and spread like Trojan horses.

When tracking software is abused, there can be a significant impact on privacy. If a smartphone gets infected with mobile spyware that was sideloaded with a third party app, the phone's camera and microphone can be used to spy on nearby activity, record phone calls, log browsing activity and keystrokes, and monitor the phone owner's location.

Adware is advertising supported software. It often downloaded free from the web, but contains banner advertisements that create revenue for the company. Adware will usually, like Spy ware, install components on your computer that will send marketing information whenever you are online. Unlike Spyware, Adware contains a disclosure telling you that they will be using your information.
Ransomware
Ransomware which is often called CryptoLocker, CryptoDefense or CryptoWall, is a family of malware that takes files on a PC or network storage, encrypts them, and then extorts money to unlock the files.

Ransomware is one of the most widespread and damaging threats that internet users face today. Since the infamous CryptoLocker first appeared in 2013, we’ve seen a new era of file-encrypting ransomware variants delivered through spam messages and Exploit Kits, extorting money from home users and businesses alike.

The current wave of ransomware families can have their roots traced back to the early days of Fake AV, through Locker variants, and finally to the file-encrypting variants that are prevalent today. Each distinct category of malware shares a common goal – to extort money from victims through social engineering and outright intimidation. The demands for money have grown more forceful with each iteration.
