Is External Source dangerous?

No matter what extension you are eager to install, it can be the vulnerability for your computer. External Source is not an exception. All browser vendors produce security patches and bother about the safety of their users. But if you install any extension, then software companies cannot ensure that your PC will not be infected. Internet swindler can use the add-on like a door to the computer. Surely there is a good effort to escape from this situation: install add-ons from well-known and reliable vendors only. But is not an absolute protection from hackers and computer threats. I advise not to install browser extensions at all.

But if you still want to install any browser extension so you should be ready that the program will have approval to record your sensitive data that you leave on various social networks and can pass it to the third parties. You should understand that to install a browser add-on is the same thing that toinstall software. Will you download a program if you do not know its vendor? I think, no. So, you also should think about the extension that you are eager to install.

External Source, as a promotional extension, is more dangerous, because you cannot be sure that the promotional message is real and that the web address that is mentioned in the announcement is safe. If you are eager to use External Source or any other add-on that shows you special deals then be ready that it is able to cheat you.

Manual and Automatic Removal Methods?

You should understand that manual ways of removal that delete External Source from browsers are absolutely secure and you can execute them not being afraid that you injure your computer. I should notice that these ways of removal are productive, so you will succeed and the extension will be eliminated together will all its manifestations. It is also an easy method; it yields only to the automatic way of removal. But occasionally, using this technique users are surprised that the PUP exists again in the browser and they have to find any other techniques to remove it.

But manual technique that instruct you to delete some files and registry items is the most destructive one. If you risk to use this method, then you should bear in mind only one common principle: do not forget to do the backup of the registry. Also the method should be carried out just by the user that realizes what and why he should eliminate.If you will eliminate several files or registry keys that do not pertain to External Source, then your computer will not start up next time. Experts will not be mistaken and can take pleasure the efficacy of the manual way of removal.

Automatic method is the method when a user downloads any removal tool to solve the issue. This way refers to the most harmless and powerful. It is also the easiest one. You should just find the antivirus software that has External Source in its signatures. This technique is more useful because you will have the antivirus program that will protect your computer against the future incoming threats.

Concerning the sums of money that users may pay for the virus removal I should say that some removal techniques are absolutely free of charge, for example manual removal from browsers, manual professional removal (in the case if you will do it by yourselves), free antivirus software and the removal from Control Panel. But not all of them are equally effective. The information about the effectiveness of these methods I illustrate in the table that is called ‘Removal methods statistics’ below. Speaking about the paid techniques of virus removal, I should list the Computer Repair Shop Service and paid Antivirus software.

These methods are the most forceful. In spite of the great difference in the price (Repair Shop service depends on the complexity of the issue and may cost up to $300, but paid antivirus costs up to $60) these removal techniques are almost equal in the effectiveness and in the results. I should also notice that paid antiviruses always has support service (sometimes free) that will solve your problem like in an expensive computer repair shop.

Paid Antivirus $35-70 +++ +++ up to 1 hour
$0 +/- +/- up to 3 hours
