Adware, Spyware & Viruses

Viruses

Every computer can be vulnerable to viruses, and protecting your computer requires constant attention. Every computer with Internet access should have antivirus software installed. Computers which connect frequently to the network or are always on the network are at the greatest risk for infection. DECS staff is very experienced in cleaning an infected computer and helping to prevent infections. Keep in mind that sometimes the scope of the infection may require a complete reinstall.

The common signs of virus infection are similar to those listed below for Spyware/Adware. It is very important to make sure your antivirus software is kept up to date regularly.
