Ok so I discovered the other day that my HP laptop had a Trojan virus. Leading up to me finding it and removing it it had been running extremely slow. Also the same day, a little green monster popped up on my Pandigital tablet and said I had a virus, so I assume they were connected, which led me to believe it could have traveled to all my computers on my home network. But thankfully my other computers were fine. So on my laptop, windows defender came up and said I had a Trojan virus and that I should remove it, which I did. After that I restored the laptop to factory default settings. but now it runs extremely slow and will freeze for long periods of time and sometimes the keyboard doesn't work and the mouse pad doesn't work at all! I have to use a wireless mouse. I removed the hard drive and scanned it with COMODO on my other computer and it found no threats. Oh, also I ran CCleaner while my laptop hard drive was connected to my computer to see if I could clean out the registries etc. Why is it running so slow and how can I fix this?

it sounds like you arent running any real antivirus software or firewall.

windows defender is crap. even on the new windows 8 it is suggested to use something substantial.

when you get an infection you could clean it up with an antivirus however the best thing to do in such a serious case is to start from square 1. format the hard drive and reinstall windows and all of the drivers. then before you connect to the internet install a real antivirus and you should be fine.

virus such as the now old blaster32 worm can spread into every single file on the pc. while it may be possible to remove the safest option is to reinstall after a wipe.

personally i recommend kaspersky internet security. i trust nothing else myself although there are other good products as well. just search for top 10 antivirus programs and pick one in your budget

The best thing to do is to do a fresh windows install to completely remove all infections on that pc. If you have a recovery disk or a recovery partition in windows even then this should be fairly simple. if not you should look into some better virus scanners. Windows defender is not one of the most reliable. as far as the free market of antivirus goes I would suggest either AD-Aware or Avast

So are you guys saying to re install windows all together. And I agree ssddx, Windows defender blows, it's just that I don't use that laptop too much and didn't bother. I use COMODO on my PC.

I'm not saying that, I'm asking if I should completely re install Windows and it's drivers?

That would be the best option. There isn't many virus or malware issues that cant be solved through a format and fresh install. Its your first option if at all viable for sure.

That's true but typically when you erase a drive or reformat it and then reinstall a fresh copy the restore point and back up and everything in it typically are deleted as well. However if the virus is rooted too deep and not even a reformat/reinstall will fix it then the only other option is a whole new HDD or several "wipings" not erasing of the entire HDD

Wiping is what business' are required to do through commercialized specialized software. Deleting something or erasing it mean it can be still somewhere deep in the coding of the drive. that's why specialist like SRS can pull up just about anything off of a drive. Just because you delete or format your drive does not mean that there isn't traces of the files left that a data management professional can find. Wiping is suppose to be much more secure although even so most companies usually wipe a drive several times and afterwards sometimes even physically destroy/shred the drive.

your best bet would be to format your hard drive during the reinstall process yes.
