What is a malware? It is a software, malicious in nature, built to steal confidential data, harm a computer’s potential to perform well or spread across to infect other devices using the same network. There is more than 60,000 potentially dangerous software released every single day. Cybercriminals are always advancing their techniques, building software that looks so much like legitimate programs that any user will be fooled. Our PC cleaner software works to clear junk or cache files that make a computer run slower. We advise clients to use a good antivirus so that a malware cannot steal or corrupt your photos, videos, files, documents or the entire hard drive. We bring you today, a brief history of some of the most malicious software till date.
Conficker
Conficker was first traced in 2008. Like many others of its likes, it would target any vulnerabilities in Windows to carry out a wide variety of attacks. Sometimes it would be phishing emails or malicious codes and at other times it would be cracking user passwords or hijacking Windows with the help of some botnet. It successfully managed to infect 15 million Microsoft server systems. Some of its famous victims were Ministry of Defence in the UK, French Navy, and Norwegian Police department. The reason we say, start with installing the best PC cleaner and always use the latest version of a good antivirus like Norton.

Zeus
This was a wildly successful and infamous Trojan that stole banking details through keystroke logging and form grabbing. Then it would try to install CrytoLocker, another malware we will talk about next. It was spread via phishing emails as well as drive-by-downloads. Even the US Department of Transportation became one of its victims. Zeus exists even today, in different forms, as its source code was leaked. Try our PC cleaner free trial to see how it protects your computer from getting infected by undesired search results, malicious ads, and phishing emails. However, antivirus and firewall protection is compulsory as well.
CryptoLocker
You can not cover this subject without mentioning CrytoLocker, the ransomware that as early as 2013 would spread through email attachments. It encrypted the user files, not letting the user access it. To send a decryption key then, the hackers would charge money. Sometimes when people did not have a backup, they lost vital information saved in such files. Though Evgeniy Bogachev, its creator, was caught later by joint efforts of Europole & the FBI, we always recommend our PC cleaner kit users, to keep the backup of all important documents. After all, CryptoLocker managed to harm 500,000 users.
Duqu
Duqu first came to the limelight in September 2011. Its source code is mostly borrowed from Stuxnet, a malicious worm. It worked against industrial targets, gathering intelligence. Duqu 2.0, its latest version, is a highly sophisticated malware. This version was signed with Foxconn's legitimate digital certificate. It happens o be a leading Chinese electronics manufacturing company. Thus, the device operating systems let Duqu load and run without suspecting it at all.
