Some malware is quiet and works in the background. A lot of it, though, gives itself away. If your computer is doing any of the following, it is worth having it checked.
Malware runs its own tasks in the background, and that steals resources. A computer that was fine last week and now crawls is a common sign.
Ads appearing where they should not, especially on the desktop or over other programs, and a browser that keeps sending you to the wrong site, are classic infection symptoms.
If your browser suddenly opens to a page you did not choose, or searches go through an engine you have never heard of, something has taken hold.
Apps you did not install, or your usual programs crashing and misbehaving, both point to malware.
If people say they have had strange emails or messages from your account, it may have been compromised.
If any of this sounds familiar, do not pay any "warning" that pops up asking for money, that is part of the scam. Get it cleaned properly. See our virus and spyware removal service or call 07 3144 6777.
