So recently I noticed my pc would sometimes be really slow for a moment and at the same time my keyboard would not do anything.
As I thought I may have picked up some virus I scanned with Anti Malwarebytes and with Microsoft Security Essentials but haven't found anything other than some unwanted browser files.
Now my computer hasn't been slow lately but I cannot type certain combinations of letters. I cannot type shift together with 1, 2, 3 or = and the windows key doesn't seem to do anything.
I know it's not a hardware problem because I tried a different keyboard and it still gave the same issue for the same keys. Even using the onscreen keyboard doesn't fix this.
I've tried changing any language/input options and searched for anyone experiencing a similar issue but haven't found anything, leading me to believe there may be an issue with my installation of windows, perhaps from a keylogger or something similar.
Thank you for any help
