Slow computer after restore

ok, so last friday i restored my computer after a screen bug, with pixels or likely. i got that fixed with some anti virus program. but then this monday, i had this Windows 7 update, and it was really slow, i was letting it update, but then after some hours it said
"Windows Failed to configure update. Changing back" or something like that. so after that, i saw a new update, i updated it, it worked fine, but this tiume it was so slow, it wont let me search for stuff, like Acer eRecovery or start up the Kaspersky. can anybody tell me what to do, this is the 3rd day with sutch problems.
thank you.

Anti-Virus programs = Avast and Kaspersky. ive downloaded kaspersky before (kaspersky pure) and same download link as the other times, but the avast was first time. and im pretty sure its the right link.

and sometimes the computer starts up fine, but that's like 1 out of 10 times.
When i try to run acer erecovery, it says that i need to shut something down first. i scanned the computer yesterday with kaspersky, and that worked fine, said that i had no virus'.

I agree with Layback Bear.

Running more than one anti-virus program at the same time is asking for trouble.

Like many others I use Microsoft Security Essentials for my anti-virus scanner and Malwarebytes to take care of malware - so far, so good - and they're both free.

Further to Layback Bear's valid comments about bad links for the unwary, you might want to read this: http://www.techsupportalert.com/cont...ch-engines.htm

Well, the problem is now, that i cant get my computer to run any programs. from Cotrol Panel to Google Chrome.
nothing. if i want to run any program i need to turn my computer on Safe Mode. I will try to remove, avast to start with, and then see if that works.

if not, i will try to do as you told me.
-> last option = getting it repaired. still have free repair on it, and i will have that till March 14th.

thanks for the help. the problem was running Avast while having Kaspersky. I uninstalled Avast and its now running fine. i restarted it a couple of times to make sure that it worked fine which it does!
God bless you!

You're very welcome.

Pleased to hear everything is back to normal and thanks for updating us.
