Sam Spencer IT - Virus Removal..
Sometimes a computer will shut itself down unexpectedly, other times you may be locked out (for example in the case of ransomware), your computer may be going slow, your anti-virus (if you have one installed) may be reporting viruses that it can't remove or your antivirus may not be finding a virus at all even though you are pretty sure that something dodgy is lurking around. You may also find annoying popups or you may be being redirected to fraudulent websites.
Whenever your computer behaves oddly, it is a deeply troubling experience, not to mention a total pain when you need to do work or accomplish a task.
