What is Win32/LockScreen.AAL virus?

Win32/LockScreen.AAL is ransomware-type malware. It searches for the documents on your disk drive, ciphers it, and after that asks you to pay the ransom for getting the decryption key. Besides making your documents locked, this virus also does a lot of harm to your system. It alters the networking setups in order to prevent you from checking out the elimination articles or downloading the anti-malware program. In rare cases, Win32/LockScreen.AAL can even block the launching of anti-malware programs.

Ransomware has actually been a headache for the last 4 years. It is hard to imagine a more damaging malware for both individuals and companies. The algorithms utilized in Win32/LockScreen.AAL (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these terrible things instantly – it may take up to several hours to cipher all of your documents. Hence, seeing the Win32/LockScreen.AAL detection is a clear signal that you should start the elimination procedure.

Where did I get the Win32/LockScreen.AAL?

Standard ways of Win32/LockScreen.AAL injection are common for all other ransomware examples. Those are one-day landing web pages where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a relatively new strategy in malware spreading – you get the e-mail that simulates some normal notifications about deliveries or bank service conditions changes. Inside of the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks quite uncomplicated, however, still demands tons of recognition. Malware can hide in various places, and it is far better to prevent it even before it gets into your PC than to rely on an anti-malware program. General cybersecurity knowledge is just an important item in the modern world, even if your relationship with a PC remains on YouTube videos. That can keep you a lot of time and money which you would certainly spend while trying to find a fix guide.
