Malware is a threat which London IT consulting firms have been trying to combat since it came to be. More often than not, they're successful at keeping attacks at bay. Nevertheless, malware does get through every now and then mostly due to human error, so the next course of action is to minimise the damage with the help of a reliable London IT company. But before you can do that, you'll have to catch the following telltale signs of an infected system:
1) Everything's Frozen
Users are locked out of their accounts, devices, or networks, and none of their data is accessible. In some cases, users also get a demand for a ransom which they need to pay via Bitcoin or another untraceable cryptocurrency; otherwise, their data is gone forever. This specific kind of malware that holds systems hostage until a ransom is paid is called ransomware.
2) Pop-Ups Appear All Over
Regular pop-up blockers aren't enough to filter out persistent pop-up windows. When users click on some phishing links or download attachments from unverified sources, malware can bypass the pop-up blockers and go straight to the system. This is why security awareness training should be part of London IT consulting services.
3) Programs Crash Randomly
If incompatibility with the hardware is not the reason why an application crashes, there's a big chance it's because of malware. Programs freeze and crash for no apparent reason, even when users aren't doing anything that takes up a lot of processing power. Sometimes, programs restart by themselves, only to freeze and crash again minutes later.
4) Email Senders' Name Are Spoofed
Emails purporting to come from legitimate sources are sent out to unsuspecting recipients with requests to download an attachment or send over personal information. The display name of the sender is spoofed, so recipients think they’re replying to a trusted entity.
5) The Homepage Changed Suddenly
The homepage switched to an unfamiliar website without being changed by users. The browser also has new toolbars. After users change back the homepage and remove the toolbars, the unwanted elements still return unless the malware is removed.
6) Error Messages Look Weird
Users get warnings about how they’re running out of disk space or memory. These are often ads designed to make users click. In other cases, the error messages are real, only because malware in the system is already using up resources.
