Bitdefender Internet Security 2013 & Windows 7 x64 Ultimate Edition (& pretty fast PC-slowest part of it is sata hdd 6gb/s) - - - Lags/slows started after last program update to v16.24.0.1682, after boot, black screen before logging screen started to appear & after normal windows startup/logon, icons in the start menu ---- all programs did not shown properly (firstly showed as unidentified) and after some lag cca 20-40(depends) sec it starts slowly appear one at the time, same happens with start menu --- administrative tools icons, and moreover I noticed full windows slow down during startup... and some lags during saving/closing office documents & copying files (it lags at 100% copy completition for about 5-10 sec). After uninstalling BD and/or installing an older version (with option-do not download new files) everything works fine and fast...until that cursed update is installed... Please look into this, it is defenitly something with the last update compatibility (My amateur opinion is: caused by process vsserv.exe it uses I/O and HDD a lot)
I have antivirus settings as follows (USER MODE+AUTOSCAN-TURNED OFF):
ON-ACCESS scanning is set on custom---all file types+network shares, archives limited to 2Mb, full traffic scan, scan boot sector, scan for keyloggers, and scan ONLY new and changed files, actions-move to quarantine... and ACTIVE VIRUS CONTROL is set on aggressive.
P.S.: Tried to install Total security trial --- still the same, after last large cca 50 Mb program update lags started. Please help it is annoying.
P.P.S: 99% not a virus, I ran a full system scan with CORANTI 2012 trial & came out clean. Registry without errors & HDD not even close to full.
