We are using multiple Avast 4.x licenses (15+) in our PCs and after the 4.8 update three of them shows very hard overall slowing…
These are different DELL Optiplex machines (GX520,GX280…) with Win Xp SP2 and Zonalarm firewall.
when we are using MS Office applications together with CA-Clipper programs a simple task switch last 10-15 minutes, and sometimes an IE->Desktop switch last 5-8 minutes also…
I’m having the same problem with my Dell Dimension E510 desktop running Windows XP. I updated to 4.8 (green box) last night and then tried to restart my system this morning. It has been locked on the “Windows is starting up…” screen for half an hour now. The mouse is still working (I can move the cursor around), but nothing else is happening. Any way to uninstall the avast update?
Are you referring to slowdowns and freezes or really a crash (or blue screen of death)?
Are there any files called \data\log\unpXXXX (where XXXX is a random number)?
If so, send them to vlk (at) avast (dot) com
They may contain more information about the problem (maybe a link to this thread).
I can move my mouse, so the system hasn’t crashed. However, I’m still not able to get past the “Windows is starting up…” screen. I even tried booting using “Last known good configuration” option in XP, but I’m still not able to get through the boot process.
Is there any useful information into Control Panel > Administrative Tools > Events, specially ‘Errors’?
Do you have any other antivirus installed in your system? Did you have in the past?
Any other security programs that could interfere?
I haven’t been able to fully boot, so I haven’t been able to access the Control Panel. I just installed a new hard drive a month ago, and no other antivirus programs have ever been on it.
I would have been happy if the slowdown was my only problem. All my apps started existing unexpectedly with the “Send report” dialog.
At first I had no idea what caused it, so I did a clean XP SP2 Pro install, with all 90 odd updates. Installed all my stock apps as usual, until installing Avast 4.8.
Everything worked great on the clean install till I installed Avast 4.8. I removed it, and smooth sailing since.
By the way, I also had that failing in one or other module in my event viewer, the one ending with a 5.
I really hope this gets resolved soon before my 30day Kaspersky runs out. ???
avast is not loaded at Safe Mode.
Something else is messing your computer? Any new hardware device? Any ‘old’ one but that does not have the correct drivers installed (Control Panel > System > Hardware devices).
No, the only change is the avast 4.8 update. Since that’s the only thing that has changed (hardware or software) since the issue appeared, it seems like that has to be the problem. It’s too much of a coincidence that my slow boot process is very similar to others who are having 4.8 update issues…
I can’t double check anything because my computer won’t boot up.
I also just noticed on my Microsoft Vista laptop (which is the one I’m writing you on) that copying files from my flash drive to my laptop had become very slow. I just uninstalled avast 4.8 from my laptop, and everything now seems to be running OK again; files transfer at normal speed.
For me, at least, avast 4.8 appears to have been a snafu…
I was suffering with slow boot times and went as far as reinstalling Windows XP and going through all the processes of getting my PC back to health again only to find it was still having slow boots. I suspected maybe a imminent hard drive failure, but then thinking that Avast was updated and had started the slow boots around the same time I uninstalled Avast to see what the boot time was like after.
The result was from the 5ish min boot up that it was, to a “Normal” 15-30 sec boot.
I have been a user of Avast for some 5 years and have been very happy up till now. Don’t get me wrong I’m not complaining about the trouble free previous 5 years, but there just seems to be a problem with this latest version.
At the moment I’ve no A/V installed, I wouldn’t recommend running without, but it seems I can’t recommend this Version of Avast.
IF I can ever get my desktop to complete the boot process (still not up after 30 minutes), I will be uninstalling avast 4.8. I hope I don’t have to reformat my hard drive and reinstall XP to get to that point…
If you can’t get it to boot into safe mode, I fear it’s the only way.
Also, I wish to add to this that I’m not 100% sure that Avast has a problem as I still need to get some reboots under it’s belt, but it seems too much of a coincidence that my system has returned to normal after getting rid of Avast.
I hope you can get your system sorted without resorting to a Format, bhuie >:(
