update drivers windows 10

If you are looking for online driver detector which can find missing drivers in windows 8/7/10 and then download and install all drivers on window 7/8/10 then you came to right place because this video will show you how to get all drivers for computer by using best free driver updater software driver booster

What are Drivers?

A driver is a software that allows your computer to communicate with hardware devices. Without drivers, the devices you connect to your computer—for example, a mouse or external hard drive—won't work properly. Windows can automatically check if there are drivers available for new devices that you connect to your computer.

Driver updater tools do just what you're probably thinking - they help you update some or all of the device drivers installed in Windows for your computer's hardware.

These free driver updater programs make it easy to keep your drivers updated. Use one, and you won't need to deal with Device Manager so much, nor will you need to go find the right driver from your hardware maker yourself.

• Driver booster: 

Driver Booster is the best free driver updater program. It's compatible with all versions of Windows and makes updating drivers simple.

Driver Booster can be scheduled to automatically find outdated drivers. When new updates are found, you can easily start downloading them from inside the Driver Booster program so you don't need to go out to an internet browser to grab them.

Before you install a driver, you can see how the new driver version compares with the currently installed driver, which is helpful.

I like that Driver Booster creates a restore point before installing a driver in the event something goes wrong with the installation.

There's an option in the settings to install drivers in the background, which hides installation wizards and other popup messages. This is handy so you don't have to click through so many windows when installing new drivers.

how to draw a polygon in autocad 2018 - polygon command in Autocad 2018

A Polygon is a single object having many sides ranging from 3 to 1024. In AutoCAD, you can create regular polygons having sides with equal length. There are two methods to create a polygon. These methods are explained in the video.

Topic covered in the video are as follows:
1) create a polygon by specifying the number of sides, and then specifying the length of one side.
2) create a polygon by specifying the number of sides, and drawing an imaginary circle (inscribed circle). The polygon will be created with its corners located on the imaginary circle. You can also create a polygon with the circumscribed circle. A circumscribed circle is an imaginary circle which is tangent to all the sides of a polygon.

I have drawn one triangle, rectangle and pentagonal to explain in this video.

Hackers Exploit 'Telegram Messenger' Zero-Day Flaw to Spread Malware

A zero-day vulnerability has been discovered in the desktop version for end-to-end encrypted Telegram messaging app that was being exploited in the wild in order to spread malware that mines cryptocurrencies such as Monero and ZCash.

The Telegram vulnerability was uncovered by security researcher Alexey Firsh from Kaspersky Lab last October and affects only the Windows client of Telegram messaging software.

The flaw has actively been exploited in the wild since at least March 2017 by attackers who tricked victims into downloading malicious software onto their PCs that used their CPU power to mine cryptocurrencies or serve as a backdoor for attackers to remotely control the affected machine, according to a blogpost on Securelist.

Here's How Telegram Vulnerability Works

The vulnerability resides in the way Telegram Windows client handles the RLO (right-to-left override) Unicode character (U+202E), which is used for coding languages that are written from right to left, like Arabic or Hebrew.

According to Kaspersky Lab, the malware creators used a hidden RLO Unicode character in the file name that reversed the order of the characters, thus renaming the file itself, and send it to Telegram users.

For example, when an attacker sends a file named "photo_high_re*U+202E*gnp.js" in a message to a Telegram user, the file's name rendered on the users' screen flipping the last part.

Therefore, the Telegram user will see an incoming PNG image file (as shown in the below image) instead of a JavaScript file, misleading into downloading malicious files disguised as the image.

"As a result, users downloaded hidden malware which was then installed on their computers," Kaspersky says in its press release published today.

Kaspersky Lab reported the vulnerability to Telegram and the company has since patched the vulnerability in its products, as the Russian security firm said: "at the time of publication, the zero-day flaw has not since been observed in messenger's products."

Hackers Used Telegram to Infect PCs with Cryptocurrency Miners

  During the analysis, Kaspersky researchers found several scenarios of zero-day exploitation in the wild by threat actors. Primarily, the flaw was actively exploited to deliver cryptocurrency mining malware, which uses the victim's PC computing power to mine different types of cryptocurrency including Monero, Zcash, Fantomcoin, and others.

While analyzing the servers of malicious actors, the researchers also found archives containing a Telegram's local cache that had been stolen from victims.

In another case, cybercriminals successfully exploited the vulnerability to install a backdoor trojan that used the Telegram API as a command and control protocol, allowing hackers to gain remote access to the victim’s computer.

"After installation, it started to operate in a silent mode, which allowed the threat actor to remain unnoticed in the network and execute different commands including the further installation of spyware tools," the firm added.

Firsh believes the zero-day vulnerability was exploited only by Russian cybercriminals, as "all the exploitation cases that [the researchers] detected occurring in Russia," and a lot of artifacts pointed towards Russian cybercriminals.

The best way to protect yourself from such attacks is not to download or open files from unknown or untrusted sources.

The security firm also recommended users to avoid sharing any sensitive personal information in messaging apps and make sure to have a good antivirus software from reliable company installed on your systems.

Meltdown/Specter-based Malware Coming Soon to Devices Near You, Are You Ready?

It has been few weeks since the details of the Spectre, and Meltdown processor vulnerabilities came out in public and researchers have discovered more than 130 malware samples trying to exploit these chip flaws.

Spectre and Meltdown are security vulnerabilities disclosed by security researchers earlier this month in many processors from Intel, ARM and AMD used in modern PCs, servers and smartphones, among other devices.

These CPU vulnerabilities could enable attackers to bypass memory isolation mechanisms and access everything, including memory allocated for the kernel containing sensitive data like passwords, encryption keys and other private information.

Researchers from independent antivirus testing firm AV-TEST detected at least 139 malware samples, as of today, which are related to these CPU vulnerabilities, as shown in the growth graph.

You can find SHA256 hashes for all malware samples here.

Meanwhile, cybersecurity firm Fortinet also tracked and analyzed many malware samples 'trying to exploit' recently disclosed CPU vulnerabilities, most of which includes re-compiled or extended version of the JavaScript-based proof-of-concept (PoC) exploit released last month.

"The rate at which the cybercriminal community is targeting known vulnerabilities is clearly accelerating, with the WannaCry and NotPetya exploits serving as perfect examples of the need to patch vulnerable systems as soon as possible," Fortinet said.

"Which is why our concerns were raised when we recently learned about some of the largest vulnerabilities ever reported—ones that affect virtually every processor developed since 1995 by chip manufacturers Intel, AMD, and ARM."

Another news makes this situation, even more, worse—Intel halted all its CPU firmware patches for the Meltdown and Spectre flaws last week after it caused issues like spontaneous reboots and other 'unpredictable' system behaviour on affected PCs.

So, until Intel and other vendors do not come up with stable security patches for the Meltdown and Spectre attacks that don’t cause systems to break, users are recommended to keep their operating system, web browsers, antivirus and other software up-to-date.

Autodesk inventor tutorial 2018 - inventor constraints explained

Constraints are automatically applied as you sketch. The constraint symbol on the cursor shows the constraint type. Constraints prevent unwanted changes to a feature when dimensions are changed or referenced geometry is moved.

You can add or edit constraints and dimensions to control sketch shape and size. Before you add constraints, study your sketch to decide which are needed. In a 2D sketch, display the Degrees of Freedom glyphs to determine which geometry is unconstrained, partially constrained, or fully constrained.

2D and 3D sketch geometry to include in constraint

In addition to geometry, you create in the sketch, you can select visible model edges and vertices for inclusion in a constraint. You can select a point at the virtual intersection of sketch elements.

In 2D sketches, the selected curves and vertices are automatically projected onto the sketch plane. Alternatively, you can select geometry and use Project Geometry to project it onto the sketch plane before applying constraints.

Tips for using constraints :-

Click the constraint command you want to use, and then:
1) Use inferred constraints to position geometry as you sketch. When a sketch command is active, move the cursor to show constraint symbols that indicate relationships to existing geometry. For example, a parallel constraint symbol appears when the new line is parallel to an existing line.
2) Brush the cursor along the line or curve you want to constrain to, then move the cursor into the approximate position. In cases where more than one constraint is possible, this technique overrides a default constraint in favor of the constraint you selected.
3) The order in which geometry is selected does not affect the results of a constraint operation. However, the presence of other constraints can affect further constraint application. Geometry with fewer constraints is repositioned or resized. If a constraint cannot be applied, a warning dialog box is displayed.
4) Constrain to an existing model or sketch geometry.

Note: To apply the same constraint to multiple curves, select the curves you want to constrain, then click a constraint command.
