I have bought Net Protector Anti-Virus for my Windows 7 system. The task manager often gets filled with multiple instances (often 30-40) of Net Protector processes such as MAILGEN.exe and GZIP.exe and other non-antivirus processes such as PROCDISP.exe and conhost.exe. The issue is that sometimes it freezes the computer completely such that the fan speed audibly increases, and at times I cannot even move the cursor. Mostly, this happens right at the start-up after logging in. I have to turn off my computer by holding the power button for a few seconds. I don't prefer to uninstall the anti-virus, so I don't know what to do.
