Can you please help me about a problem with blue screen and viruses?
Hello guys. I want to ask something about the computers and viruses. You probably know the internet addresses that give free live stream of sports games. There are many ads on the screen and when you try to close to watch the game, it just pops another sites, mostly my antivirus program cancels them. I was trying to open one of the stream links and suddenly the screen went blue. I was so worried that I didnt take a not about its code, because I thought that a virus did the blue screen since those streams were full of infected things.
After the computer installed windows files, I opened it with the safe mode and immediately run my malwarebytes anti-virus full scan. It found nothing, so I wa relieved and then opened my windows 7 in normal mode. But I am finding out that it became really slow. It is not really bad and can be tolerated, since i have 8 gb ram and intel i7 processor, but it is slower than ever.
My question is, what should I do? Can you advise me a reliable scan programme which is free, to clean my system? Because I dont want to format my laptop in the first place, unless I have to. Its a long process and dont want to install all things again.. (I will do it eventually in 4-5 months) Can you advise anything to do, or to be protected from those kind of viruses? (I wont go into those pages again, please be positive and assuring) .
Thanks to anyone who can read this long and worryful question.

How to remove a virus - by Tumbleweed_Biff at Yahoo.com
Top free AV products
Qihoo 360 Internet (arguably the best), ZoneAlarm Free, Adaware Free, Commodo Free, Avast, Avira, AVG
Kaspersky, eSET, and BitDefender are the top paid AV products.
(Links to four rescue disks are at the bottom, but there are many, many more out there. Most AV providers have one, usually free.)
I) The best solution is to back up your data and perform a factory restore. Install a reputable AV program after the restore and download the latest updates for Windows and your computer before restoring your data.
II) That not being practical for many, try either of the next two methods:
(Please note that it is important to use one of these two methods as you need to boot and scan knowing that no viruses are already in memory. If you try and install an AV product on a machine already infected then there is a decent chance that the virus will be able to hide/relocate from the scanner.)
1) On a clean computer, download 1 or more free bootable AV products. The following link provides a number of such: https://www.raymond.cc/blog/13-antivirus-rescue-cd... or http://tinyurl.com/l2hkp6f
(There is a handy product called sardu (www.sarducd.it) which will create a flash drive/Cd capable of having multiple AV products built into it. It isn't perfect yet, but it does do the job pretty well. I keep a copy on a flash drive for whenever I go to someone's house to help with computer problems and I have a number of other diagnostic tools included as well.)
2) Create the bootable media and include the latest virus definitions
3) Boot the infected/suspect computer by using the bootable media and run a full/complete/deep scan of the computer using preferably at least two different ones. No AV product gets them all, but 2 different products should find and remove just about anything.
B. Alternative method:
1) remove the hard drive from the infected computer
2) slave the drive to a clean computer which already has at least one AV product already installed with the most current definitions. You can do this by installing it into the case (for a desktop) or by putting the drive in an external drive case which you can get for the low teens $. These can come with USB (get at least USB 2.0), eSata, or Thunderbolt connections.
3) From the clean machine, run a full/complete scan of the slaved HDD. The computer should already be booted when you connect the external drive, with the AV product already resident in memory (it will have an icon down next to the clock). Then open the AV and run it on the drive. In an ideal world, you should really use two different AV products. MalwareBytes Free is an excellent choice (and my preferred) for on-demand scans like this.
III) If you are unable to do the above, then download and install an AV product and then run it at its deepest level scan. This is not the ideal method as many viruses can hide from AV products if they are already in memory and running before the AV software is executed. There are numerous free AV programs. I strongly recommend two different AV products and one Adware/Spyware product. For free AV, I would typically recommend Qihoo 360 Internet, ZoneAlarm Free, Avira, AVG, or Avast as the installed resident (always running) AV solution and Malwarebytes as a secondary, on demand AV product which I run on a weekly basis. For Spyware and Adware, the two top performers there are AdAware (Lavasoft.com) and Spybot Search and Destroy (safer-networking.org) Both offer a free and paid version. The free version is good, the paid version offers more bells and whistles, just like with the AV products.
Once the virus(es) is/are removed, change any and all passwords having to do with anything important like e-mail, financial-banking logins, etc. as those have probably been captured and sent to the author of the virus.
Separate from the others I will offer to you is Kaspersky's TDSSKiller. Not an actual Rescue Disk by itself, it is at the very top of the list of root-kit finders/eliminators. You should run this in addition to at least one of the others:
