In general, teaching assistants or TAs are people who do the organizational part of teacher’s work. They are support staff, who can afford to concentrate on individual students and their problems, while a teacher operates the entire class. This kind of support is often provided by parents who want to spend more time with their kids. It is also facilitated by the fact that school TAs are often not required to pass any entry-level exams (in the UK) or required only a high-school diploma (in the US).

What to Do if Your Browser is Bombarded with Ads
Mac users often encounter issues that completely spoil their web browsing experience. What can be more annoying than huge pop ups and aggressive advertisements blocking the screen and preventing user from getting access to necessary info? Is it some kind of virus? No. No reason for panic. Most likely adware has lurked somewhere in your system.
The core difference between viruses and adware is that adware is being installed on your Mac only if you allow this.
How can it happen?
Nowadays most websites contain commercials. It results in revenue for site owners hosting these ads. There is nothing bad in small ad banners if it does not cover half ot the sceen and interfere site navigation process. Users always have the option to make it invisible using third party ad blocking extensions. Adblock plus is my choice in such case.
Unfortunatelly adware makers use deceptive methods to force people to install browser modifications that make web surfing almost imposible. Probably there is no user on the globe who intentionally installs it. Usually ad-injection(aka adware) software comes from third-party download sites. Applications you download from such pages may have been customized to install both the application you want and the ad-injection software. If your Mac has adware installed, you might be bombarded with pop-up windows, ads, and graphics while surfing the web, even if “Block pop-up windows” is selected in Safari preferences. Ad-injection software might also change your homepage and preferred search engine.
How to prevent installing adware on your Mac?
You should always remember and carry out 4 easy rules to protect your Mac from catching adware.
RULE 1: Install good antivirus software
RULE 2: Enable Gatekeeper to prevent suspicious applications from being installed on your machine. To do this:
- Click on the Apple logo
- Choose System Preferences
- Click on spen Security and Privacy icon
- Select “General” tab
- Click on the lock and type your admin password
- Check Allow apps downloaed from Mac App Store and identified developers.
You may find more info how Gatekeeper works here.
RULE 3: Avoid installing apps from unreliable sources
RULE 4: Never click on pop up ads and fake tech-support alerts/offers claiming you won free iPhone or million dollars. Free cheese is only in the mousetrap. After accepting the offer or clicking on it you may end up with numerous extensions and plugins to your browser causing more and more ads. If you need qualified tech support call Apple or use Apple Certified Techicians’ assistance built into some applications.
“Prepare your fist to kill adware beast”
If you are unhappy adware victim there are several workarounds to eliminate it. Unfortunatelly in most cases it is time consuming process. Prepare a cup of your favourite tea and get ready to eliminate adware consequences.
Open your web browser with the ‘Shift’ key held down and check if any suspicious extensions left (I’d suggest you to uninstall all extensions):
If you use Safari:
- Open the browser and click on its name at the upper left corner of the Desktop, select Preferences (or Press ‘Command(⌘) – ,(comma)’) → Extensions, if you see any unknown extensions, click on their names and choose Uninstall.
Examples of ad-injection extensions: Cinema-Plus Pro; Flashmall; GoPhoto; Omnibar; Shopy Mate. Spigot Extensions: Amazon Shopping Assistant;Ebay Shopping Assistant; Searchme; Slick Savings.
Note: These are not the only extensions causing advertisements. Unfortunately adware database is constantly growing and this information may be outdated soon. We will update this list as soon as new malicious app spreading adware will be discovered
- Use Command + Shift + G shortcut in order to use Go to Folder option.
Paste the following in order to search and remove Buca Apps, Conduit, Downlite, Genieo, MyBrand, Trovi, and Vsearch. Press return. If there is no such item on your Mac you will see the message. If it will open new window with the item you have searched for drag it to the trash(this may ask for admin password)
- Restart your Mac and empty the trash.
If you are Google Chrome user:
Open the browser, click on its name at the upper left corner of the screen and select Preferences (or Press ‘Command(⌘) – ,’) → Extensions, click on Trash icons to the right of extensions’ names. Delete Chrome’s cache files, and other browsing data. For additional info check this support article
