Hello!

 

Recently I have been noticing some suspicious looking redirect links in my Firefox browser. When I click to go to a website I will quickly see in the bottom left hand side some suspicious redirect links before ending up where I would like to go. Example; I want to visit a website and I see 342sfd87634.cloudfront.net in the left hand corner before taking me to the website. I don't receive any popups, and I always end up on the correct website. It seems to happen randomly. I have ghostery and adblock on firefox. My browser has been a little slower than usual so I thought it may be something to do with that. I'm using Windows 8.1

 

I have used Malwarebytes Anti Rootkit & Anti Malware (including in safemode) / Adwcleaner and Avast Scanned and everything came back clear. I also reset my firefox browser and reinstalled my Firefox addons (Ghostery and Adblock).

 

Any help is much appreciated thank you!

Those blinking links are usually harmless and they actually come from that particular site you want visit.

Many sites use those kind of links for different purposes.

cloudfront.net for instance: http://aws.amazon.com/cloudfront/

If your browser behaves normally there no reason for any concern.

My browser seems to be okay its just very slow and I thought by pinging those websites before connecting it may have been whats causing me problems. Maybe my ISP is throttling me a little. Thanks

Usually when a computer is infected with malware there most likely will be other obvious indications (signs of infection) that something is wrong.

Which browser is slow?

Did you check other browser(s)?

I'm using Firefox 34.0.5, still somewhat slow while using chrome too. Webpages occasionaly timeout (it will look like the page has loaded, but then suddenly timeout or reset) I can stream video perfectly (ustream or bbc live news) for example but youtube loads much slower (always needs to buffer). I'm not giving you too much to go on but thank you for the replies! :)

Well, while browsing the web avast detected and removed a trojan when I tried to visit a website (i guess it was a dodgy site) & now I have a Homegroup icon on my desktop out of no where. I don't know when it appeared, but I have gone to Administrative Tools > Services > and then right clicked and stopped both Homegroup listener and Homegroup Provider. The icon is still however on my desktop. Any ideas?

 

Thanks for all the help

...The appearance of this Homegroup icon is not because of any virus – it just appears to make its presence once in a while – randomly!

For me, Homegroup shows in the Desktop Menu and in Windows Explorer but not on the Desktop screen itself so this is not unique to Windows 8.

Hey just an update, everything seems to be working perfect. I'm not sure what happened before, but after resetting my browser, running my scans - and disabling that homegroup situation, my internet is working perfect again.

 

Thank you for all the help and information!!
