Weird Computer problem

[Siyano_v1legacy]

1- Random computer freeze doing only internet surfing
sometimes my firefox stop responding and I unable to close it (and eventually can't do anything with computer), sometimes its completely freeze my computer, most of the time I have to restart it

2- Random unable to connect to internet site
this one is more sporadic, I click on one of my favourite site, "Unable to connect, please use the refresh or reconnect later" I immediately refresh, everything is fine

3- Weird advertisement spam.
I feel like I am "infected" with some kind of ad ware, I can't seem to get rid of it, its seem to re-install itself every 2-3 days and then appears when I surf around.
(I am usually very very cautious about toolbar and such when installer program)

Thank

I am not sure about your first problem I am afraid.

The second problem may be due to a problem on the server's end. Too many users, could be a whole host of issues, I would say that the problem is not your end.

I recommend search and destroy, it is a brilliant application that will search for ad ware and remove it.

I hope this helps.

I forgot to say for the second problem, its happening just not for one site

Well it could still be server side issues, you don't know how common these issues are.

Firefox freezing just sounds like Firefox to me. However, I'd say scrub your PC completely clean using AdwCleaner, Hitman Pro, Malwarebytes and your anti-virus software just to check for any nasty programs that might be lurking on your system. You should defrag your PC too if you haven't already(I use I0Bit Smart Defrag). I'd run a deep clean with CCleaner too(It works wonders in general maintenance). If the worst comes to the worst you could always do a fresh install of your OS.

Hello, I am A+ Certified Computer Tech, so maybe I can be of assistance.

From what I have read of your issues, the signs seem to point to an infected computer. Total LOLige above has the right idea, you should probably scan your computer but just to be thorough, I would do Full Scans on all of them to make sure you do not miss anything. I personally recommend Avast and Malwarebytes. Also, if you know how, I would recommend you open up your task manager and look at your processes to see if anything is taking up more resources than it should be taking.

All else fails, I recommend using System Restore. It puts your computer back to state in the past so if this issue is recent, try using System Restore to regain your computers stability.
