Avast slowing down internet browsing
« on: July 17, 2013, 08:22:26 AM »
I'm an avid fan of Avast as my go-to anti-virus, I often recommend it to friends who ask which anti-virus they should download, but I'm not too sure if I would recommend it to my friends now.

Lately I've been experiencing very slow page loading times through my internet browser (Chrome). Initially I tried reinstalling Chrome and using a different browser (Safari and Firefox), but they all suffered from the same  problems when loading pages - Pages take at least ten seconds to load, formatting goes funny on occasion, images load very slowly (if they even load at all). None of these issues occur when I load the respective pages on my iPad (loading the desktop version of the pages). In addition I scanned my computer for malware and viruses with no positive results on either.

Eventually I deduced that the root cause of my problems was Avast's Web Shield. Disabling this shield eliminated all the problems I had been experiencing.

I hope these problems get fixed in the future as this feature has blocked numerous malicious attempts made towards my computer in the past.
