Best free antivirus for android

1.Avast mobile security

As a genuinely free app for the Android platform, Avast! Mobile Security is offering an impressive range of tools. It has antivirus protection, it scans your apps to provide details on what they are doing, and it has a Web shield that scans URLs for malware.

There are various additional tools in the package and the best of the bunch is the anti-theft component. The app is actually based on an old app called Theft Aware which Avast acquired. The anti-theft feature is hidden and allows you to remote control your smartphone using SMS. So if you lose your phone, you can remotely lock it, locate it, or wipe it. You can make it play a siren sound, lock down the SIM card, and prevent USB debugging as well. It’s a comprehensive solution for theft protection.

If you have a rooted device then there’s also a firewall that allows you to control network traffic. You can block access to Wi-Fi or the network for specific apps which is handy for security and potentially saving on battery juice as well.

According to the latest AV-Test report of 25 popular Android security apps, Avast is a solid option with an overall detection rate of 98.1 percent. Although it is not top of the charts in terms of malware detection, the extra functionality (including the anti-theft tools and a firewall for rooted devices) still make it worth considering. It has a light footprint with no discernible drain on battery life and no impact on general performance. It also returned no false positives.

The fact this app is completely free, has a wide range of features, and offers protection for rooted devices, makes it a strong contender. If you’re looking for a security solution for your Android smartphone, and your primary concern is malware and safe browsing, then this could be the right app for you.

Avast Marketing Director, Milos Korenko, has assured us that “There might be a paid version in the future but that won’t have an impact on the free version. It will continue to be available and loaded with features.”

2. 360 Security - Antivirus Free

A major player in China, developer Qihu burst onto the scene and claimed the top spot in AV-Test’s September 2013 report with a virtually flawless detection rate of 99.9 percent, the highest of any of the security apps tested. In the latest September 2016 report, it achieved a detection rate of 99.9 percent. The focus with 360 Mobile Security is firmly on detecting and nullifying threats to your system. It has a very streamlined, elegant design. It’s extremely lightweight, and it’s completely free. A standard real-time scan will safeguard your device from malware, spyware, and the threat of infection. It’s also capable of detecting and fixing system vulnerabilities and cleaning up idle background apps to help your phone run more efficiently. There’s a privacy advisor and a tool to clear your usage history.

The latest version of 360 Security boasts a lot of extras, including a junk file cleaner, memory booster to free RAM, a power saving option, app management, privacy with encryption, and anti-theft tools for locating or remotely wiping your phone. For a good blend of usability and strong protection, you should think about 360 Security. It offers smooth performance and a host of extra features, so it is bound to appeal to many users.

3. AVL

Some of you are probably just looking for malware protection that’s as barebones as possible. If you don’t want anti-theft tools, or identity protection, or any of the other possibly superfluous features that come in many security apps then AVL will suit you. This app scored a 99.8 percent detection rate with one false positive and AV-Test found performance was good with no undue impact on speed or battery life. AVL can scan a variety of file formats beyond APKs and it’s designed to be fast and efficient. It does also offer call blocking capabilities.

Get it on:

3. Anti-virus Dr.Web Light

Dr.Web was a new name to us, but its high lab rating shows it really should be considered. The app lists fewer items than some here in its requirements of what it needs to check on your device. Even so, it proved more than adept at spotting malware from almost every 'family' attempting to gain access to Android devices.

In all but 7 of the 19 malware families included in the AV-Test procedure, Dr Web scored above 95.3%, while the remainder were in the creditable 65 to 90 percent segment.

Unfortunately, you won't discern how effective Dr.Web is from its interface. Even while you scan through the security messages relating to what it accesses, a worrying orange bar behind the EULA window shows that all is not well.

This turns out to relate to the automatic monitoring service that Dr.Web offers. Clicking the orange bar has no effect. In fact, you need to click the Off/On radio button to the far right of the next option down - SpIDer Guard [note to production: deliberate random upper-case]. The screen then turns a virulent combination of green - to signal protection is now active - and turquoise.

How can I increase my computer speed

1.   Check your hard disk space. As a rule, you want to keep at least 15% of the hard disk space free to keep the computer running smoothly. Simply go to My Computer, right-click on Hard Drive, and go to Properties. There you'll see a pie chart of your free versus used space. If it’s mostly full, you'll want to start by removing unnecessary programs and files; it it’s not, you probably want to tackle the actual way your computer operates.

2.   Remove any programs you do not use. Go to Control Panel > Add or Remove Programs (or Uninstall a Program, depending on your operating system) to find a master list of programs installed on your computer. Some things will strike you as useless immediately, in which case you can remove them right away. Others won’t look familiar to you and may require you some research.

3.   It may help to see how often you use the program. If you right-click one of the column titles above your program list (ex. Name, Publisher, Size, Installed On, etc.), you should be able to add additional characteristics by which to judge your programs. For example, find Last Used On on the list of options and check it; a column displaying the last time you used each program will now appear and can also be used to sort your programs. Some programs will not have been used in years and may be candidates for deletion.When in doubt, don't remove anything you don’t recognize; it may be critical to the function of your computer – and if you delete twelve different things only to discover that your computer no longer works properly, it will be very difficult to determine where exactly you went wrong.Don't forget to empty your recycling bin.Prevent unnecessary programs from starting when the computer boots. The more programs try to run while your computer initializes, the slower everything will be. Revise your startup programs by altering your system configuration via MSConfig.

4.   Install an anti-virus program, spyware scanner, and an anti-malware. The fewer bugs, viruses, and bits of adware your computer has to manage, the more time it will have to devote to other processes. While you're at it, make a point of keeping Windows up-to-date; not only will this keep Windows itself in better shape, but some viruses ride in on Windows updates that are downloaded way after the fact (and therefore not monitored as closely).

5.   Run a Disk Cleanup. This can clean up hundreds of megabytes of temporary files – sometimes even gigabytes (if you have Windows XP, Vista, or 7). It will also open a window in which you can chose what to delete. Go to My Computer, right-click the Hard Drive and select Properties, and then click Disc Cleanup (within the General tab). Check all the boxes except for the game files and setup files.

6.   Run a Disk Defragment. This will reconfigure the way the hard drive stores information for maximum efficiency. Go to My Computer, right-click the Hard Drive and select Properties, then go to the Tools tab and click Defragment Now.

7.   Check for any disk errors. These will also slow your computer down. Go to My Computer, right-click the Hard Drive and select Properties, then go to the Tools tab and click Check Now under the Error-Checking area. When the dialogue box opens, check both boxes.If you get a window saying that Windows can't check the disk while it's in use, click on Schedule Disk Check and then OK. It will run on your next reboot.

8.   Turn off indexing. Go to My Computer, right-click the Hard Drive and select Properties, then unclick the box indicating that the drive should be indexed. Don't do this if you actually use any of the Windows Search functionality. The background indexing is what makes those searches fast and Windows is already very good about not getting in your way to do indexing while you're trying to do something else.

9.   Clear your Prefetch folder. Windows saves a file of the program you are using to make it start up faster. After years of use, this folder gets stuffed with irrelevant programs.

10.   Open Notepad and type:del C:\Windows\Prefetch\*.* /QRundll32.exe advapi32.dll, ProcessIdleTasks(Copy and paste this text to ensure you don’t make any mistakes.)Save as faster.bat (the .bat extension will run it as a batch file).Run it! Simply double-click the file to initialize. In a few moments, the command prompt will      disappear and your programs should run more smoothly.

11.   Change Prefetch Parameters. This a dangerous task to complete unless you follow these steps exactly. If you're not sure about anything, don’t continue.Go to Start > Run and type regedit to initialize the registry editor.Go to HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Control>Session Manager>Memory Management>Prefetch Parameters to access the parameters.Double-click Enable Prefetcher. Once the new window pops up, there should be a small, editable text box with the number 3 in it. (Windows allows 4 options: 0, 1, 2 and 3.) 3, the default, fetches everything.Change this to 2. Your PC will boot a lot faster and your PC performance shouldn't be affected.Click OK and then close regedit.

12.  Add RAM to your computer. To see if you need more RAM, initialize the Windows Task Manager by pressing CTRL+ALT+DELETE. Under the Performance tab, find the area devoted to Physical Memory. If the Free amount hovers around zero but the computer is still slow, you may need to take your computer in to add RAM or even add more RAM yourself.

13. Restart your computer. The computer usually needs to reboot to implement changes.

14. Remove gadgets you don't use. All gadgets that are running slow down your computer.

15. Log off the users who do not want the computer. Switch user your account then if you see that many users are logged in, log them off.

now your computer speed faster
