Here are the suggestions from avast! Support to remedy this problem whilst not really affecting your security: They suggested to change a few things which I did and now my CPU performance is back to normal, I am getting 5.3 seconds in wPRIME so a 0.3 seconds performance hit is fine. I then submitted a support ticker to Avast which as usual, took almost 2 weeks to be answered. This surprised me because according to the latest AV-Comparatives Performance tests, it shows that Avast Antivirus is one of the lightest solutions out there. I then installed NOD32 and Kaspersky Antivirus (separately off-course) and benchmarked again but I would get 5 seconds in wPRIME so that was all good and the issue seemed to only be there when Avast Antivirus was installed.

No help was offered and I was just told that any Antivirus would cause a small hit on the CPU performance.

I then posted this thread on the avast support forums:Īvast Antivirus Pro affecting CPU Performance Without an Antivirus installed, I would get a score of 4.9 seconds, with Avast Antivirus Pro installed, I would get 7.5 seconds (the lower the score the better).

I tested using wPRIME running a 32M benchmark. So a while back, I noticed that my CPU performance was decreased.
