Hi: Rather complete instructions with screenshots for manually removing UniDeals from your system and your browsers can be found in this Feb/2015 article: www.pcrisk.com/.../8664-ads-by-unideals This article also discusses how you probably installed this pest (typically comes bundled with other freeware, and is installed by default when you select the "Quick" or "typical" install option), and how to avoid this in the future. Another option that I personally use to remove adware and can highly recommend, is the free adware cleaner program AdwCleaner. Instructions on how to download and use this utility are here:www.bleepingcomputer.com/.../adwcleaner I don't think an anti-virus is enough to block adware these days. I use the free browser extension Adblock Plus, which is available for all the major browsers, including Chrome and Firefox. You can get it here:[URL]
so a a few days ago, i started to notice UniDeals adds that show up in chrome and firefox. i googled it up, somehow managed to disable it from ever reappearing in firefox, but it still persists in chrome. i did already delete the unideals folder in the x86 files. and the program is not listed in add/remove programs. unfortunately, my computer never made a restore point. (i've had it for 4 months and it never created a restore point?????) so i can't just restore my computer which i would most definitely do. how can i get rid of this piece of and get a adware antivirus? i've done 2 full scans from windows defender, but it's not picking anything up. 
UniDeals adware can't remove
