Reasons explaining-why Anti-virus fail to detect Trojan virus?

Following stated causes may not come as a surprise for you, however, we still suggest to have a quick glance over the list-so, you don’t miss out any of them.

Outdated Virus Signature

All authorized and genuine anti-virus software release virus signature regularly. Now, as a user- if you forget or ignore to update this list of code signatures in your device then, the malware can work as a vulnerability of the system.

Bad/ Inactive Firewall

Old, obsolete, or inactive firewall will also allow malware to move freely on device.

Multiple Anti-virus programs

To add more security on device, if you’ve installed more than one anti-virus on same drive then, you are not only fooling yourself but the device as well- where it’s installed. Because, it would become easy for any virus software to escape these security walls.

Want to know-how? The, stay tuned! You’ll soon get your answer.

Free anti-virus

Obviously, your system gets vulnerable to many viruses- if you keep using free anti-virus program to detect all types of malware present on device. This is because free AV software doesn’t cover all the security parameters.

Corrupt Anti-Virus Program

When any spyware breaks anti-virus files on device, there’s no chance of malware getting detected by the installed security system.

Even after treating the causes, still, viruses cannot be detected by anti-virus then, find your solution further.

Signs of Virus on Device (When AV program can’t detect)

It’s good if you are able to notice any virus in device especially when your anti-virus program fails to do so. But what if they sleekly escape from your eyes?

We are saying this not to make you panic but understand the significance of signs stated below. So, if you don’t want to end up breaking your Windows/Mac/Android device due to some virus- then, always be alert on seeing the below signs:

Sign 1: Slow Performance

Corrupt software or programs like viruses, Trojan, and spyware continuously send information on motherboard, which can hog the processing power of your device. As a result, your device may start performing all functions slow than usual.

Sign 2: Excessive Program Crashing

Programs or apps on device may crash due to any XYZ reason. However, if this crashing action keeps on repeating at a regular interval (more than usual) that implies your device could have a Virus.

Sign 3: Device Memory is full despite low usage

After clearing most of the device and SD card memory, if you still get the message-“No space is available” then, sure short your device has infected files, which are hogging all the device memory.

Sign 4: Excessive Battery Drain

Like device memory, the virus on your software machine can also drain out a lot of energy from the device battery.

So, whenever- the battery of your device starts draining faster than usual- do check if there’s any malware present.

Sign 5: Unnecessary Adware pop-ups

Generally, the pop-ups on device are not malware. However, if the adware pop-up even after the browser is closed that could mean it’s the malware in form of pop-up that’s trying to modify, steal, or regulate the device.

Sign 6: Device Overheating

Out of many reasons for device getting overheated-malware infection is one! So, don’t forget to check for this cause.

Sign 7: Web homepage changes automatically

On opening your default browser- if you see some page other than your set homepage- Go to its settings. Then, under General tab – change the homepage (that you want to set).

Web homepage changes automaticallyNow, reboot your browser. This time, if you again find some other webpage then, it implies, there may be certain infected files in browser, which are mysteriously changing the settings without permission.
