When I first start my computer all of browsers work and are fine. But when I exit out the processes in task manager are still there and I can't get rid of them. Then I try to open the browser again and it just doesn't open.
uhhh virus?
best way of fixing this
reinstall?
I've reinstalled and idk what to do now
I think they mean, "You should reinstall your OS".
Back up data, reformat your drive, and reinstall whatever OS you are using. This sounds fishy to me and I wouldn't do anything short of a full reformat and reinstall (only way you can be certain your pc is clean from malware)
Sometimes, when an virus is found and attempts are made at eradicating it, system files are damaged. This might be what happened.
BlackRabMo has the right i idea but if you have a backup try that first.
