I have been pulling my hair out in frustration trying to resolve what may be a lingering problem due to the bleeping Pokki Start Menu Update pop-up that I naively didn't realise was an attack when I switched my Lenovo PC on on Saturday and then when opening Firefox straight after found that it, along with IE and Chrome, had been hijacked with the homepage-web.com redirect.
I followed all the instructions I found here for resolving the homepage-web.com hijack and here for the Start Menu Update and removal of Pokki and getting my browsers back to an unhijacked state and Pokki off my system (still furious that such a potentially malicious piece of software came preloaded on what has otherwise been a beautiful Lenovo PC purchased late December!).
Everything appeared fine and working correctly, but Saturday was also the day I needed to renegotiate my TV/broadband/phone package with my provider and basically have had my cable broadband upgraded to 50 MB there and then (they upped the speed on the line while I was on the phone with them), but was also sent out a new router as my older setup from them was not guaranteed to support the new speeds.
All appeared fine - happy computer was back again. Yay.
But a day or so later when I next went on any of the tumblr blogs I follow I would receive a connection was reset message in random image frames and they would load fine if I hit try again (this was in Firefox), I tried the same pages in IE and Chrome and got similar persistent but random loading issues with images here and there but ony tumblr blogs.
I have had no issues in any browser with any other websites returning "Connection was reset" or error loading page - I've tried lots of image heavy sites I usually frequent like other blogs, pinterest, facebook, no other websites are giving me problems - just tumblr. Grrr...
Tuesday my new superhub arrived and I thought maybe the change of modem/router would fix the issue, but no. Still experiencing the same problem just on tumblr - it's as though the browsers are too quick to say they can't load something as it is almost instantaneous that the "connection was reset" display appears while otherwise they would still be trying to load the page (like they do on other devices in the network).
I have cleared the cache and cookies of firefox, I have reset it, I have rest IE completely, I have uninstalled Chrome which was only a recent install with no bookmarks, and have run it with the cache completely cleared and still the problem persists.
I am not having this issue with tumblr on any other computer connected via my wifi - my Windows 7 laptop is loading the same problem pages fine in IE and Firefox, another windows 8.1 laptop I borrowed to test this is loading them fine in IE and Firefox, and my iPad is loading them fine. These three are all connected via WiFi.
So, I disconnected the Ethernet cable to my PC and tried the same pages via WiFi on it and still no joy. I have been clearing the history and cache frequently between attempts. But stilll nope.
I have run frequenet Malware Bytes scans and Adwcleaner scans since this all kicked off on Saturday. Malwarebytes returns nothing - no threats, adwcleaner returns the same false positive results for the registry but nothing else hinky.
I have rebooted the new router - no difference.
So I am banging my head against the wall here, because everything appears to be hunky dory except for this niggling issue with loading tumblr sites that have reblogged image posts.
It makes me question whether there is still some malware or something nasty lurking that is not being picked up and really, why am I getting these "connection was reset" issues just on tumblr when everything else is working fine? It's just not logical and I just want to get this resolved. I hate illogical things like this, mysteries bug me!
I'm currently away from my home PC for the next few hours, but wanted to get the ball rolling if at all poss. on what the next steps to take are.
If anyone could help I would be so grateful!
