I have Kaspersky Antivirus installed and lately the Internet has slowed down as well have programs been slow in responding and opening up. I had a tech with my internet provider come out and he turned off Kaspersky and the Internet speeded up tremendously. The same thing happens with slow responding programs, once I shut off Kaspersky, they respond very fast. This situation started once I returned from vacation. There does not seem to be any viruses on the computer. I have run a complete check and no viruses were found. When I open IE and watch Task Manager, the CPU usage spikes, as well when I open a program. The process spiking CPU usage is avp.exe, Kaspersky. There is no difference using other browers. I do have e-mail checking turned off, because the ISP provides e-mail scanning. Does anyone have any other ideas as what can be done to rectify this slowdown?
